Kegerator Beer Line Temperatures & Reducing Foam with a Recirculating Fan

Back in 2014, I had what I would call a reasonably well put together and balanced kegerator.  In spite of that, for years, I had dealt with the dreaded first foamy pint of beer.  After that pint of beer, beer would pour great.  That is until a significant delay between pours – overnight or a few hours.

A Closer Look at Kegerator Beer Line Temps

cln_img_5476The setup.  I have two temperature probes in my kegerator.  One is zip-tied to the top of a beverage line.  The other is zip-tied to a can of beer.  That’s how I have kept the probe in my kegerator for a long time with the thinking that the mass of the can of beer will help to stabilize temperature readings and give overall stable and accurate readings.  That can is sitting on the compressor hump of my Kenmore Deep Freeze (8.8 Cu ft Model 16932, out of production).  That puts it about mid keg.

Beer Line Temps – No Recirculation Fan

The cause of the problem is pretty clear.  Heat rises.  That means the top of your kegerator is going to be warmer than the bottom of your kegerator.  That warmer beer foams when it comes out.  The faucet and shank are also warmer.  That warmth adds to the problem.

How much is the temperature variance?  Of course, this will vary from setup to setup and climate to climate.  I was relatively shocked by the temperature difference in my own kegerator.

img_temps

The top reading about mid keg and the bottom reading is the top the top of my beer lines.  These are about 22″ apart.  This graph shows a point in time variance between the two of 14.9 degrees F.   My beer is about the temperature I want it, but the top of my serving line is much warmer.  That difference in temperature causes the first pint to have too much foam.  Pours that happen soon after the first are fine.  The tubing, shank and beer are relatively cool.

Q & A with Dr Chris White – 27 Questions Answered!

White Labs recently announced new PurePitch yeast packaging for homebrewers.  The new packaging goes hand in hand with a new propagation method White Labs is calling the Flexcell Process.

White Labs Description of Flexcell:
Instead of traditional stainless steel fermenters, the patent-pending FlexCell process allows White Labs to propagate yeast with no exposure to the environment all the way to packaging, ensuring its quality and purity.

More about PurePitch Packaging:

  • Since the yeast is grown and packaged in the same material the new PurePitch packaging is actually a part of the fermentor, and its contents have never been exposed to the environment.
  • PurePitch Packaging is breathable and allows CO2 to escape. Reduced chance of gas build-up.
  • This packaging will maintain the yeast in a more stress-free state.

Look for new PurePitch Packaging on Homebrew Finds – connect with HBF – when it’s released sometime this fall.

As part of the release of PurePitch Packaging, Dr Chris White PhD, President and CEO of White Labs wanted to hear directly from Homebrew Finds Readers.  We asked you for your questions about the new packaging and yeast and fermentation in general back in July.  Questions and answers follow.

Thanks to all who submitted questions and thank you to Dr Chris White!

Look for new PurePitch Packaging on Homebrew Finds when it’s released sometime this fall.

Q 1. When White Labs propagates yeast, what measures are taken to ensure that no mutations take hold?

A.  Our attention for looking for mutations hasn’t changed with the new technology. We built a big back end to our yeast production at the beginning. We have a specialized team that works with freezes – check for mutations, by specialized plating, genetic analysis and performance. We are constantly checking for mutations. In addition we minimize time we have yeast on plates and our propagation is limited to 17 days. These tools and personal that separates us from being a yeast propagator and we maintain these yeast in there integrity is one of our missions.

Q 2.  Gluten-free brewers are mostly restricted to dry yeast strains, because liquid yeasts are shipped in a medium that contains gluten. Is the PurePitch packaging gluten free, or is it still the same as before?

A.  The yeast within the PurePitch packaging is the same as before. We do, however, carry a product called Clarity Ferm, which can help reduce gluten to under 10 ppm in beer.

Q 3.  What are the ideal mash parameters, yeast strains, and fermentation temperatures to accentuate each of the following ester/phenol characters in a hefeweizen: clove, banana, and bubble gum?

A.  Hef yeast strains that we have are selected to maximize these characteristics. Anything that encourages yeast growth will increase those 3 flavors. Pitching less and higher fermentation temperature that encourage growth are 2 examples. Aerating less will also encourage growth – another parameter that can increase esters.

Q 4.  What yeast or blend of yeasts would you recommend to try and recreate keeping at home?

A.  If traditional methods are followed for keeping our WLP775 WL cider yeast is the best choice.

Q 5.  Is it possible to dry yeast at home for storage and later use?

A.  You will get very low viability dry yeast at home, so it’s not recommended. If you did, you would need to check the viability after rehydrating.

Q 6.  Would it be possible to make a Servomyces substitute at home? If so, could you suggest how it could be done?

A.  No, it is not, as it’s a patented process.

Q 7.  The new packaging says it’s breathable so it allows co2 to escape. Even though it’s breathable- I would think if the package is sealed the yeast would be under considerable pressure during reproduction and may have a negative effect on yeast health during its growth. Is that not really a factor or is it accounted for somehow?

A.  During the propagation, the vessel is constructed with blow-off valves to allow all of the pressure to escape while the culture is being oxygenated and growing.

Q 8.  Is the new packaging permeable to oxygen? If so does that negatively affect the shelf life of the product?

A.  We are still conducting trials to test the shelf life, but initial trials indicate the
shelf life may even be prolonged.

Q 9.  As temperature fluctuates there is the chance the package will also take in outside air. Especially for people who get yeast delivered in warm months. The yeast temperature fluctuate from cold to warm and back to cold. Have you done tests to see how much outside air gets in and it’s effect on the yeast?

A.  The film technology is only allowing gas pressure to escape, but not the other way (like a one-way check valve)

Q 10.  You indicate the packaging material is recyclable. What material is it made of as some states have restrictions?

A.  #2 plastic

Q 11.  Will the new packaging have more strain specific information regarding optimum conditions?

A.  Yes, we’ve broken the yeast strains into categories with more specific strain-related recommendations, including Brett/Bacteria.  We grouped them into 6 different strain styles. Within the 6, we have specific information for example, like Lagers. The 6 strain types are differentiated by color on the package. Furthermore we are actively pertaining more information on our strains via our tasting room and brewery to add more information to our yeast descriptions that are found online and printed material.

Q 12.  How is a uniform cell count, or a known cell count, maintained in each unit when the culture is packaged using this new packaging technology?

A.  We’re using automated cell counting technology to validate the consistency of the culture prior to final packaging.

Q 13.  Was there an issue with the old packaging that prompted for the redesign (I understand the improved packaging for retailers to take up significantly less shelf space, but was it a yeast reason or was this a response to increases in vial costs or actual issues with the old storage methods?) Will this keep yeast more viable for longer periods of time?

A.  This was prompted to reduce the amount of transfers yeast makes to be propagated, concentrated, tested and packaged. From our first thoughts of this process, it was driven by the desire to make better yeast. We have always liked the vial, but we didn’t want that to cloud our desire to make better yeast. By utilizing this new technology, we can offer yeast that has never been exposed to the environment. We have seen better viability over time as well, which is due to release of CO2 and from less time and handling to fill packages.

Q 14.  You sell ~100 billion cells per package. These packages include instructions indicating they are directly pitchable into 5 gallons of wort up to ~1.060. However, every brewer of any experience seems to accept as gospel that yeast starters are required for nearly any batch – Jamil Z.’s online calculator claims that 100 billion cells are barely enough for 5 gallons at 1.034, for example. Why, then, has White Labs not marketed a package of 200 or 250 billion cells for homebrew use? This would allow homebrewers to brew beers in the meat of the homebrewing space – say 1.050 – 1.075 – without the trouble of making starters for every batch.

A.  We are actually increasing the number of cells per package to 2.5 to 3 billion cells per ml. And laboratory grown yeast won’t necessarily follow the pitching rate guidelines since they are very healthy. The pitching rate recommendations traditionally refer to re-pitched yeast. Also, you are not getting a lot of growth from a starter unless it is an adequate size.

Q 15.  The number of cells in each pack strains the minimal requirements for a 5 gallon session strength beer (ie. 250,000 cells/ml/P). And that’s given 100% viability, which is almost never likely due to unavoidable transportation and long term storage issues at LHBS. With the new packages will there be options for larger volumes, (e.g. 200e9 cells) to help address these? Minimal costs additions, offset by new pack savings, would definitely drive market share higher.

A.  See answer to #14. With yeast it is similar to beer pricing, if you buy 1 liter of beer it is usually only slightly less than the price of 2 pints, because you have to make twice as much on the manufacturing side.  But we are open to different sizes in the future, it just won’t be as ‘less
expensive’ as people might think. Please keep the feedback on sizes coming to White Labs.

Q 16.  What temperature should I make a yeast starter at? Room temp, warmer or cooler?

A.  Room temperature or warmer (close to 75F or 24C)

Q 17.  How long should I let a yeast starter run on a stir plate? Is there a recommended duration, or some visual indication that the colony is ready?

A.  24-48 hrs. The only visual confirmation you can get would be to count the yeast and examine them under the microscope.

Q 18.  Should I drain the starter wort first? Should I chill the starter to help it settle before doing so?

A.  It is mostly personal preference but if you are decanting the starter wort you should let it settle and chilling it will accelerate that.

Q 19.  What temperature should I pitch at? At target fermentation temperature, or some measure below?

A.  We recommend pitching at 70, then bringing the temp down to fermentation temperature when fermentation begins.

Q 20.  Can I over do it with oxygen in the wort when I pitch my yeast? I have been doing some experiments with extending the time that I run O2 on my wort when I pitch. I have a commercial size O2 tank & regulator and .5 micron stone that I use to oxygenate my 10 gal all grain batches. I noticed that increasing my O2 run improved the start on my ferment and produced better all around results. So, I started extending the time that I ran my o2, just to see what would happen. I expected to see a point where my results started to fall off. This did not seem to happen. I continued to extend my oxygenation up to about 35 minutes at about 1 liter per minute. I do not have the equipment to do cell counts and so my results are fairly subjective, but, it seems to me that at least up to 15 minutes I observed improvements in fermentation. Can I hurt the cells with a 15 minute O2 run and at what point am I just wasting my time. Using the large o2 cylinder, the cost is very minimal and I am not concerned with it. My primary interest is producing better beer. What will make my yeast perform best?

A.  In homebrew set ups, it is very hard to over oxygenate. Once saturation is reached, excess oxygen will not go into solution. So at that point extra oxygen will be wasted. In commercial operations, they sometimes get over oxygenation because they are oxygenating in line, which can create over pressure which allows more oxygen to dissolve into solution.

Q 21.  In your book you mention how important adding oxygen to wort for proper fermentation. Is there a specific amount to add correlated to original gravity? Such as X liters for 5 gallons of 1.040 and Y more for every increase of 5 points?

A.  It is not about flow rate of oxygen, that will be different for every set up and every beer. What you want is 8 to 10 ppm of dissolved oxygen in the wort. The difficult part about knowing that is most people do not have the equipment to measure dissolved oxygen.

Q 22.  Any brewer who’s tasted their wort knows it tastes much more bitter than the beer it is eventually turned into by yeast. To what extent is the pre- and post-fermentation IBU difference dependent on yeast strain? If it does vary by yeast strain, do you think this would be a useful value to include in each yeast’s spec sheet?

A.  Yes, it is affected by different yeast strains. We have been studying this in our brewery/tasting room, and are working on a publication to make this information available to everyone.

Q 23.  Will White Labs be able to produce consistent yeast blends with this new method of packaging?

A.  Yes

Q 24.  Will the work with Yeast Bay migrate over to the new packaging?

A.  Yes

Q 25.  Will the new method of packaging effect cell counts of Bret and Lacto?

A.  No, the cell counts will remain the same

Q 26.  Is it possible to clean up a batch of yeast using water purification drops (the kind used for camping)? What are the chances of killing the yeast or reducing its abilities?

A.  No, the yeast would be killed.

Q 27.  When making high-gravity beer can I viably use distiller’s yeast in the secondary fermentation chamber after the primary yeast has done most of the work to lower the FG a little further?

A.  You can always try it but not all distiller’s yeast are considered high gravity yeast

Hands On Review: Captain Crush, Adjustable Three Roller Grain Mill – Including Mash Tests

Important Update

Initially, I was very happy with this mill, but I did end up having problems with the rollers.  I have tried many adjustments but have a hard time getting the rollers to engage.  For what I paid for it, I feel like it should have lasted much longer.  My Barley Crusher continues to work after years and years and it cost much less.  Others have commented on this review along those same lines. I like a lot of things about this mill, but would love to see them address the quality issues related to the rollers.

This post still has some very interesting crush and mash test results that make a great case for taking control of your brew day by crushing your own grain.

The Captain Crush Grain Mill


The box.  It’s large.


Not only is it large, it’s heavy.  My Ultraship 55 (usually my grain scale – Review) shows a whopping 21 lbs 7 ounces.


Over half of that weight is the roller mill assembly itself.

One of the nice things about the Captain Crush are the easy adjustment knobs.  You can change settings quickly and without tools.  The current setting is NB’s recommended “optimal setting”.  Also notice the drill connection shaft toward the top left of the mill body.

The official size of Captain Crush’s Hopper is 11 lbs.  I’ve found that it can hold at least that much.  This picture shows the vast majority of the malt bill for 1 Hour IPA – continuously hopped IPA.  The malt bill for that is 13 lbs.  The hopper is holding just under 12 lbs… 11 lbs 14 oz.

Mash Trials:

These are side by side mash tests using the Captain Crush Mill on “optimal” setting vs store crushed grain.  The Rahr 2 Row both milled and unmilled were sourced at a reputable local homebrew shop.  Note that it did not come from Northern Brewer.  To produce as consistent results as possible, I measured everything (water and grain) in grams to the nearest single gram.

Procedure:

  1. Weigh 906 grams (1.997 lbs) of grain
  2. Weigh 2,715 grams of strike water (.717 gallons)
  3. Heat up strike water to 162 deg F.  Overheat by a degree or so and then stir back down to temperature.  It’s easier to hit a stable temp going down vs hitting it going up.
  4. While strike water is heating pre-heat mash tun with 1/2 gallon of 212 deg F water.
  5. Place grain (inside of bag) in cooler.
  6. Add strike water.
  7. Stir and record temperature.
  8. Mash for 60 minutes.
  9. Drain first runnings.
  10. Grain back in mash tun.
  11. Add 1,884 grams (.497 gallons) of 212 deg F water to the grain and stir.  I normally would not sparge with boiling water.  I used boiling water to take one more variable out of the equation.
  12. Drain second runnings.  Let grain bag sit on strainer for 5 minutes.
  13. Record volume and gravity.

cln_img_9919
Each test used 906 grams (1.997 lbs) of grain

cln_img_0008
Each Test used 2,715 grams of strike water (.717 gallons).  For some reason I didn’t use the tare feature when I weighed the water.  The pitcher ways 547 grams.  That makes the water 2,715 grams.

81ZONpZSWNL._SL1500_
This 2 Gallon Rubbermaid Cooler Served as a Mash Tun.  I used a paint straining bag to contain the grain.  This process worked pretty well.  This would be good equipment and technique to use for small batch all grain brews.  For consistency, I pre-heated the cooler prior to placing grain and strike water into it.

cln_img_9980
A 5 gallon paint straining bag contained the grain.

My Thermapen reading mash temperature.  The temperatures of each trial mash were close but not identical.  One read 151.5 deg F, the other read 152 deg F.  I consider that to be within the limits of what I can test and produce in my kitchen.

Results Store Milled:

My Atago Pal-1 Digital Refractometer reads 10 Brix.  That’s on OG of 1.040.  Rahr 2 Row should provide 37 points per lb.  That means there are a total of 74 points in the two lbs of grain I used.  .859 gallons of 1.040 wort comes out to a total of 34.375 points or an efficiency of 46.4%.  That’s low.  Although, the point of this particular experiment is to compare two grinds, not to measure the efficiency of one technique vs another.

Store Milled Grain (left) vs Captain Crush Mill using “optimal” setting (right). Click to zoom.

Mash Test Conclusion:

  1. The store Milled Grain I used produced an efficiency of 46.4% vs an efficiency of 62.6% when using the “optimal” setting on the Captain Crush.  That’s a comparative improvement of 34.9%.
  2. The Captain Crush’s “optimal setting” produces a great crush.
  3. Grain crush is a big part of efficiency.  Store crushed grain can be on the under crushed side.  Some stores do this to help prevent stuck sparges.  That’s a valid strategy and it may be way you want.
  4. If you are looking for more control over your mash milling your own grain provides you with quite a bit more control.  It also allows you to buy grain in bulk and crush right before brewing.  That preserves freshness and leads to better tasting beer.

Conclusions

Initially, I was very happy with this mill, but I did end up having problems with the rollers.  I have tried many adjustments but have a hard time getting the rollers to engage.  For what I paid for it, I feel like it should have lasted much longer.  My Barley Crusher continues to work after years and years and it cost much less.  Others have commented on this review along those same lines.

Juno Choi’s Patagonia IPA Recipe

logo

Juno Choi With a PIle of Hops

One of the homebrews that stood out to me while attending a past Homebrewer’s Conference, homebrewcon in Grand Rapids, Michigan was an IPA that was served by Brewer’s Supply Group (BSG) at their booth at the Conference. It was… delicious.  Roasty, great hop character and easy to drink.  I swung by for two samples and shortly returned… for a third and it was gone.  After the conference, I got a hold of BSG to ask about the beer.  I learned that it was formulated and brewed by Juno Choi.  Juno kindly shared the recipe with me and I’d like to share it with you.  Thank you Juno!

The recipe features 100% Patagonia Malts from Chile.  Those were new to me and I think relatively new to the homebrew market here in the US, because… I had a very difficult time sourcing the grain for this recipe.  After looking around a bit, I contacted Bryan at Great Fermentations.  They already carried Patagonia, just not not all three varieties that this recipe calls for.  Bryan kindly sourced the remaining grains and has stocked them at Great Fermentations.  Thank you Bryan!

On to the recipe…

Fermentables:
10.8 lbs Patagonia Extra Pale Malt
.6 lb Patagonia Caramel 90L
.6 lb Patagonia Caramel 190L

Hops:
60 Minutes – 2 OZ Motueka
10 Minutes – 2 OZ Pacifica
1 Minute – 2 OZ Nelson Sauvin

Mash for 60 Minutes at 152 deg F

Ferment with Safale US-05 at 68 deg F

About The Beer, Estimates:
OG: 1.061 at 70% Efficiency
FG: 1.017
ABV: 5.76%
IBU 73.31
SRM 17.78

Extract:
The all grain recipe features Patagonia Malts from beginning to end.  Extract Patagonia Extra Pale Malt doesn’t exist.  You could still get the same idea by substituting 8 lbs of Liquid Malt Extract for the Extra Pale and steep the caramel malts.  That gets you the same gravity and pretty well everything else, although the SRM does go up to 18.74.  Again, not the exact same beer, but you will get a lot of the great roasty flavors from the Patagonia Caramel Malts and all of the hop character.

The RT600C is waterproof.  Not just splash proof or “kind of waterproof”, it’s waterproof.  IP65 rated to be exact.  That means you can put this in a dishwasher – up to 190 deg F.  To illustrate I’ve submerged it in my trusty Rubbermaid Commercial Brew Day Pitcher [Review]

Accuracy:


Testing with ice water in my Lifeline Vacuum Insulated Stainless Growler [Review].  The RT600C reads a perfect… 32 deg F.


Still 32 deg F, side by side with my ThermoWorks Thermapen [Review]


I’ve experienced different boiling temperature on different days using the same equipment and testing methods.  Boiling temperature is a moving target.  It is based on elevation and atmospheric conditions.  The day of this test, boiling point was a consistent 211.8 deg F as read by my highly accurate Thermapen.


The RT600C reads 211.5 deg F.  It’s reading to .3 deg F low.  Well within it’s stated accuracy of +- .9 deg F.

Response Time:


This video shows a response time test using the RT600C.  I’m counting the start of the test as right when the metal basket hits the water. The probe of the thermometer is submerged at 1 second into the video. It levels out at 139.6 deg F at 7.85 seconds. That’s a response time of 6.85 seconds. For .1 deg F resolution, that’s a great response time. For comparison, I’ve tested the Thermapen and gotten a response time of 5.4 seconds (at 130.4 deg F).  The Thermapen is an amazing thermometer, but it’s also about 5 times the cost.

Auto Shut Off (now included)…
In the original version of this review I noted that the RT600C does not have an auto off feature.  Not a huge deal if your version (like mine) doesn’t have auto off.  What you can do is… shut it off :).  If you do forget, the batteries are relatively inexpensive.  Update: ThermoWorks has changed the design.  The RT600C now includes and auto-off feature.  If for some reason you wanted a version that has no auto off, that’s found in the RT600B.  That one stays on like the RT600C used to.  Not very helpful for homebrewers.  I think that’s generally used by food service professionals trying to test dishwasher temperatures and such.

Some of the RT600C’s features:

  • Waterproof.  In fact it is dishwasher safe up to 190 degrees F.
  • Has a super fast read time- 5-6 seconds.  IP65 rating.
  • Accuracy to ±0.9°F (±0.5°C)
  • C/°F switchable
  • Only requires 1/4″ of the probe to be submerged to get a reading
  • Has a .1 degree resolution
  • Records Minimum and Maximum Temperatures.  You can use this to monitor serving and fermentation temps.
  • Long Battery Life – up to 5,000 hours of continuous use
  • NSF Certified
  • Tough Commercial Design
  • Manufactured by Thermoworks.  Warranty – The RT600C comes with a one-year coverage on material and workmanship including any failure in the thermometer circuit. Includes online, email and phone access to the ThermoWorks technical service group.

I purchased my RT600C back in October of 2011.  As of this update (September 2015) the same unit continues to be an amazing thermometer.

With years of practical use in homebrewing and beyond, I can recommend the RT600C as a great homebrewing thermometer.  Considering the features, performance and cost, this is arguably one of the best values for your money.

Hands On Review: Gemco 4 Oz Measuring and Tasting Glass

I use several of these puppies around my brewery and more.  I’ve used them for general measuring and as beer taster glasses.  I’ve also used them for espresso shots in coordination with my Rancilio Silvia Espresso Machine.

Sometimes these sorts of measuring devices are to be considered… ballpark.  This photo shows 29.5 grams of water.  29.57 grams equals one fluid ounce of water.  Within the limitations of this scale – Fast Weight MS-500-BLK – (1/10th gram)… this measuring glass is right on.

One problem that any glass can have is markings washing off.  I haven’t had that problem (for over a year now) and I’ve put these guys through some arguably rough treatment.  As mentioned previously, one of the things I use these for is espresso.  When used for that, these get near boiling liquid poured in them.  The measurement marks still look like new.  I will say that I’ve never put these in my dishwasher.

These are rugged, accurate and versatile measuring glasses.

Hands On Review: Allied Precision 742G 1000 Watt Heat Stick with Temp Trial

Updated: July 18, 2024

What do heat sticks do?

Heat sticks help you… heat things.  For homebrewing they are helpful for getting strike and sparge water up to temp and helping to more quickly achieve or maintain a boil.  Depending on the heat stick and batch size, you could potentially use a heat stick as the sole source of heat from beginning to end.

Always use caution when handling hot items and when using water around electricity.

Make sure the components you use are compatible and rated for your intended application.  Contact manufacturer with questions about suitability or a specific application.  Always read and follow manufacturer directions.

I love PBW!

Five Star Chemicals PBW – Powder Brewery Wash – is my go-to brewery cleaner. It is a non-hazardous buffered alkaline brewery cleaner and it… works great.

PBW Guidelines and Suggestions

Why shop around?  Using the Spray Bottle Method for Star San means that I use so little Star San that it’s really not even worth price comparing.  Not so with PBW.  This is something that I go through relatively quickly.  Since we use this in bulk, why not save money and buy it in bulk.  Buy things in bulk that you use in bulk.
