Precision Laboratories Acid Test Strips For Wine (2.8 to 4.4 pH), 100-Count

I use these to track my wine PH. They work as designed

I use them for kombucha. Easy to know the PH without having to taste.

Good product,worked as advertised.

I bought these strips to test pH during wine making. Although easy to use, more color gradations between pH levels would be helpful so that guessing the closest value, or one in between the photos shown would be less subjective. Good value for the price.

I got 25 of these strips with my initial kombucha kit from Cultures for Health. They accurately measure the strength of my brewing kombucha and now I need more. The price is perfect. Other strips often are too water soluble when used (the color ink bleeds too much and impossible to compare potency). THese are my choice in the 2 years i’ve been brewing my Kombucha. BTW: I flavor it with Crystal Light cherry pomegranate flavor. Of course Amazon is the place to order from.

I received these strips the other day and used them last night for testing. I used them on my Peach wine, Watermelon Wine, and my plan tap water. I had no changes in any of the strips. I used about 3 or 4 different strips (ordered 100 pack) for each liquid. They did not adjust or do anything. No change of any color other then their original shade of dark blue from a "fresh" strip. Disappointed to say the least. My peach wine is very acidic and wanted to know the PH before bottling to adjust it if needed. Won't know till opening day sometime in the future.

They do not work with red wines. They stain red or purple....useless.
