Your cart is empty.Grapes and other fruits have variable levels of acidity which is why a skilled wine maker adjusts the acid content of the must prior to fermentation. A proper acid balance prevents formation of off-flavors, inhibits bacteria and encourages healthy yeast development. This acid test kit instantly measures the acid content in any wine and provides a reading in either percent tartaric acid (US standard) or parts per thousand sulfuric acid (European and British standard). Acid content is measured by combining a small sample of wine, the acid indicator solution and the reagent solution. Reagent is added to the sample until a color change occurs and the amount of reagent used is calculated to provide the acid content. The wine acid kit provides enough acid test solution and reagent for 50 to 100 tests. Complete instructions are included in the kit which also provide helpful formulas to adjust the acid content of the wine with various additives.

It did its job for calibrating. Good amount of product included.

Nothing special but does the job. Kit is more or less as described except there is no way it will do 50-100 tests as claimed unless you are testing very, very weak acids. I’m testing cider, home made vinegar and fruit wines and I’ll be surprised if I get 20 tests out of it before needing more NaOH solution. The NaOH solution is only 0.1 and not documented in the description. I’d prefer 0.2 as some kits have.It does work though.

This is a very very basic acid free test. The directions are not great for beginners, which this kit is made for. Cheap but does it's job.

Directions could have been better. Could include a cylinder for samples and automatic siphon.

I've been using this product to test wine. After a couple weeks it is not working correctly at all. I believe it was accurate on my first use but now every solution registers around 1ph. I tested lemon juice tap water milk and it all came out to supposedly be a pH of 1 taking half a milliliter of the sodium hydroxide reagent to turn pink. The kit has been kept in the original packaging in a cool dark room.

Followed the instructions. Result disagreed with a titration using other reagents by exactly a factor of 2. Higher. Quite unlikely the real TA was anywhere near 2.8! I suspect either the formula in their instructions is in error or they packaged a .1M NaOH solution instead of .2M. The label does not say what is in the bottle! Either way, can only suggest you stay away from this product.

Didn't seem to be very accurate. Expected it to be more like a pool test kit and it said use 3 or 4 drops of test solutuion.

If you're a home wine maker you need this kit. The price is comparable and ships quickly.
