Wine Chem 101So why chemistry? Without knowing some of the chemistry of wine, a home winemaker may be flying blind—or at least wearing dark glasses with the lights off.
Wine Chem 101 Part BIn Part B of Wine Chem 101, Bob tackles the chemistry the wine component responsible for the "zing": Acid. The two major organic acid components of grapes and grape juice are tartaric and malic acids, usually starting at about a 50-50 ratio.
Wine Chem 101 Part CIn the final part of our Wine Chem series, Bob discusses the relationship between pH and sulfite. While the titratable acid number—TA—is all about taste, the pH number is all about stability. In particular, wine pH strongly influences the effectiveness of sulfite in preserving wine’s freshness and quality. 
Fun With Chemistry: Harvest AnalysisFor the 2006 harvest, my wife Marty White and I decided to give several home kits and techniques a try. We used the SAP panel from Vinquiry as our reference and ran our own tests to match on our home-grown pinot noir and chardonnay.
By Bim P. - Malolactic Chromatography Test Kit
"Perfect service, good product, well described and promptly delivered, thanks, beverage people !!!!!!"
By Tom Y. - Great tool and easy pick up
"We used the Vinmetrica SC-300 for the first time last week and were very happy with the results and how easy and accurate the readings were. Also picking up at the trailer out front was very easy and organized. Thanks Gabe and Jane!!"
By Genevieve P. - Titrets - Convenient way to test sulfite levels
"This little kit is handy for keeping an eye on your sulfite levels. So much easier than a standard Ripper titration and so much cheaper than the electronic devices for SO2 testing."
