Hands on Review: Milwaukee MW102 and PH55 pH Meters

This review is by Homebrew Finds Contributor Brad Probert. Brad is an engineer, expert homebrewer and experienced reviewer. Grab a link to Brad’s website at the end of this review.

If you’re like me when I was new to all-grain brewing, you were reading every post and homebrew book out there trying to figure out why your mash conversion efficiency was so much lower than you planned/wanted/expected. I came across some reference to mash pH and its effect on conversion efficiency, filed it under “way too complicated and science-y for a hobby”, and moved onto something easier to relate to. I bought a pack of pH test strips and used them once and realized the color looked slightly like none of the marks on the box and simultaneously like all of the marks. I again shoved this pH stuff to the background of my homebrew brain.

Now, several years in, I’m more comfortable with my processes, equipment and recipe creation, and am looking to chase out any variables that can negatively affect my beer. Reading brewing literature in pursuit of better beer, I can no longer ignore the emphasis they place on a target mash pH when brewing light colored and light bodied beers. So I find myself back wanting to measure and start to understand my mash pH.

How Long Does Star San Last?

Updated: 6/18/2024

Star San is my sanitizer of choice. It’s food safe and no rinse. Required contact time is five mintues. It has worked very well for me for quite some time and I’m convinced that it’s one of the most economical solutions available if you use the spray bottle method. See: Star San Tips, Tricks and Guidelines

How Long Does Star San Last?

With regards to mixed Star San Solution: The official answer is probably… you should mix a fresh batch each time you use it. To really test the effectiveness, you need to titrate the solution and test the PPM.

Practically speaking, many homebrewers use and re-use Star San. If you’re going to do that, the solution should be relatively clear and the mixture should have a pH of under 3.5. Previously the recommendation I received from Five Star Chemicals was that the solution should by crystal clear, however, for bottles of Star San not older than 1 year (check the manufacture date on the bottle, the first two digits are the year it was manufactured) crystal clarity isn’t necessarily a requirement.
