DetailsA wine that is too high in acid will have a harsh tart or acidic taste. If the acid level is too low, the wine will taste flat and bland. Use this Acid Testing Kit to test the acid level of your must, then adjust accordingly. Our Useful Downloads above will help you with what is the proper level of acidity for my wine, and how to adjust you wine, if needed. This kit comes complete with test vial, syringe, color solution, sodium hydroxide and detailed instructions.

3.8 / 5.019 ReviewsAdequateI am a chemist and decided to buy the kit because of the price. I have never done a titration using a syringe, but it was good for determining a rough value for total acidity in terms of tartaric acid. I was a little skeptical at first but it did the job. It was very easy to use and I double checked the value using a pH meter,a buret, and my own solution of NaOH to make sure it was correct. The kit works well and is worth it.May 27, 2012Helpful, but maybe not for the beginnerKnowing the acidity is a very handy tool in wine making. With most kits and other recipes you find in books or online the acidity should be within tolerable range. Lots of recipes will even tell you how much acid blend to add. I would recommend using this kit if you are making your own recipe or if you are making wine from fruit as you cannot predict a whole lot about a given batch of grapes, strawberries, etc._x000D__x000D_Very helpful if you have some winemaking experience. A little confusing and difficult to get a reading if you are just starting out.June 4, 2013Plusses and minusesIt is hard to use and requires you have good eyesight and look at the color changes in good light. With a little practice it's usable. Maybe not for everyone, but it's not like it doesn't work.January 3, 2014February 4, 2016WorksPretty simple testing method. I had no problem getting the right result.September 24, 2017Purchased
1 year agoInexpensive and worksA pH meter is best, but then you also have to buy all the solutions and replacement electrodes. This kit is much cheaper and it works. The problem is you have to do it correctly and the directions aren't always clear. Its a little clunky as you have to gauge different shades and they can shift back._x000D_I still recommend it.November 10, 2013Only measures tartaric acidI used this product a few times and always got a low acid reading. Being a novice wine maker at the time I didn't understand the different types of acids. After learning a bit more and looking back at the instructions I realized it only measures tartaric acid, which is the principal acid in wine grapes. If you are making wine from other fruits whose principal acid is malic or citric, or are taking a reading after the addition of acid blend (which is a blend of all 3) you aren't getting a correct reading.July 31, 2015Works fineI was a little worried after reading previous reviews but if you take the time to read and understand the directions you should have no problem using this kit. It worked perfectly for me._x000D_October 8, 2012Cheap but hardMuch less expensive than a pH meter with all the "potions" (storage, 4.00, 7.00) it requires. But it took me a while to read it properly. Patience and good light is what you need.February 5, 2014Making better cider, mead, and wine!Great little kit at a reasonable price! I have some intro college-level chemistry in my past, but even without it, I’d say the kit is easy to use and comes with great instructions. The only thing that I would maybe like to see is a little plastic stand to set the test tube down in between filling it with the wine sample and preparing the NaOH. I bought this kit along with some wine pH strips for cider making after having had a few batches succumb to microbial spoilage during aging from low acid and high pH. Now that I keep my acidity in check, my troubles are gone AND the TA adjustments both pre and post ferment are making for much better tasting ciders! I can’t imagine making cider without diligent acid testing and adjustment now. It’s really helped me tone down some of my sharper fruit wines and bring life into insipid meads, too.August 29, 2018

Browse 2 questions Browse 2 questions and 2 answersWhat are the concentration levels of the Sodium Hydroxide and the Phenolphthalein? ThanksBEST ANSWER: In my kit, purchased 07/2018, the NaOH is a 0.1N preparation while the indicator solution does not specify anything beyond phenolphthalein on the bottle. The kit instructions do not appear to give that info either.Can this be used to test for acetic acid on vinager in the 4% to 6% range ?BEST ANSWER: This test is designed for overall acidity in wine and the range is not high enough to measure that high an acidity.
