Use these pH strips to test your wine for the correct acidity level; only $6.95 for 100 strips.
For dark red wines activated charcoal will reduce the pigment to make reading easier. These strips are also ideal for testing kombucha.
Minimum shelf life of 2 years if kept sealed even after opening.
Recommendations from our chemist, Scott S.:
Sometimes a spoonful of activated carbon (like the stuff used in aquariums) in a small sample will reduce the color. I have tried this with some success. It doesn’t appear to affect the pH. They will need to mix it well and give it some time to do its work. Other than that, the recommendation is to use an electronic method where color doesn’t play a role.
