DetailsThe sulfur dioxide present in must and wine is not all useful as a preservative. Some is bound to other chemical components, reducing its effectiveness as a preservative by 30 - 70%. Also, the degree of binding can change over time, affecting the ability of an adequate dose to continue providing its preservative properties. The effectiveness of sulfur dioxide as a preservative is also pH-dependent, with low pH wines requiring lower levels, and high pH wines requiring significantly greater concentrations to achieve the same effectiveness as in a typical wine with a pH of 3.3 - 3.4. The Accuvin Free SO2 Kit is divided into a Low Range (0 - 40 ppm) and a High Range (40 - 130 ppm). 10 Tests per kit.

4.9 / 5.07 ReviewsSaves you moneyIt's on the technical side so read the directions and pay attention. Its easy to use if done properly. As for the price - yup it seems high for what you get. On the other hand this is good for both red and whites, unlike the Titrets kit.September 30, 2013Good productIt works! Great on whites, but a little tricky on deep reds.July 31, 2016worked perfectlyI got this test when I accidentally put too much potassium metabisulfite (campden tablets) in my wine. I thought my wine was ruined, but this told me it wasn't!_x000D__x000D_Just follow the directions. You may have to read them twice. Put a liquid into another bottle, then mix with your juice, and it will tell you your SO2 (sulfer dioxide) levels, which is the end result of potassium metabisulfite_x000D__x000D_I didn't like the price, but it saved me from dumping 6 gallons of my wine, so it was justifiedMay 21, 2013Saved 6 gallons of wineI had 6 gallons of a red wine that I had miscalculated on and was able to adjust and save it. It's not super complex, but it's not trial, so read the instructions and make sure you understand the sequence of actions before performing the test.December 22, 2013Good testing kit for reds and whitesRead the instructions before doing anything. Its a good kit but it isn't as simple as it seems. The fact that it works for all wines is a big plus.February 10, 2014Quality controlOverall - it's worth it. It's an easy test to do if you do it slowly and carefully, just follow the directions. Its accurate and worth the money.March 19, 2014Works GreatThis product worked amazingly well, but I'm not entirely sure the price is justified. I followed the instructions for testing a recent Pinot Noir I had in the secondary and it helped me to save the batch.August 16, 2013
