Mark II Keg and Carboy Washer Mod – Adding a Stainless Steel CIP Spray Ball

cln_img_2973

Updated: September 3, 2024

I’m a big fan of the Mark II Keg and Carboy Washer.  I use mine for lots of things including… kegs, carboys, Speidel Fermenters, buckets, tubing, draft lines [See: Mark II Keg & Carboy Cleaner… As a Recirculating Draft Line Cleaning Pump] and more.  See: Hands on Review: Mark’s Keg and Carboy Washer for a comprehensive look at this great homebrewing tool.

A while back I became aware of a Stainless CIP Spray Ball (1/2″ size) via a reader tip.  Thanks to HBF Reader Sam for the original heads up on these and HBF Reader (Let’s be friends!) Chris.for the idea to use in conjunction with the Mark II Keg and Carboy Cleaner!

Find a CIP Spray Ball!

Note: The Spray Ball I used in this post has since changed specifications.

CIP (Clean in Place) Spray Balls are generally used for vessels that are too large to move.  Since they’re too large to move you… clean them in place.  If you have a larger setup, you could incorporate these into your system or routine to help clean your vessels more easily.

Hands on Review: Ferroday Stainless Steel Carbonation Cap for PET Bottles & Draft Line Cleaning Builds

This is a hands on look at a Stainless Steel Carbonation Cap by Ferroday along with some information about what these are used for and some related build projects.

What are stainless steel carbonation caps used for?

  • PET Bottles as Growlers: These are generally intended to convert 1L and 2L bottles to growlers.  Fill up a 1L or 2L PET bottle with your favorite homebrew.  Put one of these on (purge the headspace by squeezing if you want to) and then pressurize for transport.  This should help to reduce oxygen pickup and maintain carbonation levels.
  • Fine tune or rapidly carbonate beer: You can also use this cap to rapidly carbonate beer.  Same process as for transport, just set your regulator to the proper pressure and shake or agitate the PET bottle to help introduce CO2.  Or hook it up to CO2 and let it sit in you kegerator.
  • Draft Line Cleaning Projects:  I have developed three draft line cleaning projects using similar SS Caps – Build A Recirculating Draft Line Cleaning Pump | Mark II Keg and Carboy Cleaner Draft Line Cleaning Pump Conversion | Building a Simple Ball Lock Draft Line Flushing Setup

And MORE…

Universal Liquid and Gas Carbonation Caps

The really big question that needs to be answered, if you want to build a draft line cleaning setup using one of these, is whether or not it is universal.  Ball Lock Kegs have gas and liquid posts along with corresponding QDs.  Black goes on liquid, grey or white goes on gas.  They ARE NOT interchangeable.  The beauty of some stainless steel carbonation caps is that they are universal, meaning they can accept both gas and liquid QDs.  That’s very important for draft line cleaning builds because we want to connect a liquid QD to this.  The problem is, not all stainless steel carbonation caps are universal.

Build a Spunding Valve! – How and Why

June 26, 2024

A Spunding Valve allows you to maintain a set pressure.  If pressure in the vessel exceeds the set point, it is expelled.  It generally consists of an adjustable PRV valve, a tee, a gauge and a way to connect to your keg.

Homebrewing Applications of a Spunding Valve

  • Pressurized fermentation.  Ferment in a 5 or 10 gallon corny keg and use your Spunding Valve instead of an airlock.  This allows you to ferment at your desired pressure.
  • Dry hop under pressure.  This allows you to dry hop earlier while reducing oxygenation.  Active yeast are more likely to metabolize oxygen that’s introduced during dry hopping during active fermentation.  Since CO2 is not exiting beer as vigorously under pressure, wanted compounds, flavors and aromas are more likely to stay in your beer under pressure.
  • Naturally and accurately carbonate beer right in the keg.
  • An airlock replacement.  Keep the valve wide open for non-pressurized fermentations.  Only do this if you have plenty of head space.  This wouldn’t make a great blow off tube.
  • Keg to keg transfers.  Use the Spunding Valve to allow excess gas to exit the receiving keg as you transfer under pressure.  Helps you achieve a slow, controlled and pressurized transfer.
  • Fix over-carbonated beers.
  • Test for keg leaks.  Pressurize your keg to serving pressure.  Put the Spunding Valve on (with the pressure set well above your serving PSI) and note the reading.  The gauge should remain steady.  If pressure drops, you know you have a keg leak.  The digital build, see below, is especially helpful for this task,  The digital gauge reads with .1 PSI resolution making pressure changes easy to spot.  It’s worth noting that this checks the entire keg including gas body o-ring.  That spot is hard to check and other way as it’s only in function when the gas QD is on.  When the gas QD is on… it’s difficult to spray and check for bubbles underneath the gas QD.  Thanks to Scott Janish for this tip!
  • As an airlock for long term aging of beers.  Airlocks can run dry over time.  A Spunding Valve will not.
  • Utilize CO2 from fermentation for flushing kegs and fermenters.

Building a Dry Hopper for Corny Kegs – Dry Hop Under Pressure!

Benefits of Fermenting Under Pressure + The Challenges of Dry Hopping Under Pressure

Fermenting under pressure has some great benefits. One of the challenges that using this method presents is… dry hopping. When fermenting under pressure the beer is carbonated. Adding dry hops to a fermented and carbonated beer, especially one at relatively warm fermentation temps equates to a Mentos+Diet Coke sort of situation. The hops provide lots and lots of nucleation points that can cause the beer to erupt expelling foam all over the place in the process denaturing head retaining proteins.

Of course you could use these fittings in lots of different applications.  One possible application is a Spunding Valve build.  A Spunding Valve [See: Spunding Valve Resource Post] allows you to ferment under pressure, naturally and precisely carbonate in the keg, fix over-carbonated beers and more.  A similar (different manufacturer and possibly specs) fitting and barb are featured in our “Cheapest” Spunding Valve Build Option
