Wine Analysis Glassware
California is home to thousands of wineries, and nearby, the Department of Enology and Viticulture at the University of California at Davis is recognized as a preeminent center for the study of wines and winemaking. It is only natural that specific glassware for the analysis of wine would be developed in California. You can see more of this glassware in the wine analysis gallery, and check out comments from end users.
The Volatile Acid Still is a glass apparatus specific to the wine industry, for the determination of volatile acids in wine by steam distillation. Our standard glass VA still includes an aspirator pump to suck the sample out after completion of the analysis, allowing for rapid cycling of samples. Its precursor was the glass Cash Still and many people refer to these stills generically as "Cash still" or "RD80". For historical interest, see our notes on the history of the VA Still. Adams & Chittenden Scientific Glass manufactures both the VA Still and Cash Still, offering an exceptionally high quality product, with a new, improved cordset and connector, and a large capacity condenser, at competitive prices. We have been making VA Stills and Cash Stills our entire glassblowing careers. We are proud of our stills; they have a high "Wow" factor and demonstrate our skills and quality.

We were entertained to hear a SoundClip on NPR's "Talk of the Nation" on Hearing a Wine's Acidity featuring the sound of the VA Still. Thanks to Patrick Taylor of Cuneo Cellars for permission to use his words and sounds.
Our SO2 Apparatus uses the Aeration-Oxidation method to determine the sulfur dioxide content in wine, both for free and bound SO2, as described by Amerine and Ough in Methods for Analysis of Musts and Wines (John C. Wiley and Sons, 1980). A pop-up photo of this assembly "exploded" is linked here.
We manufacture a variety of glass wine thieves, including a curved barrel thief for easy access to close-packed barrel racks. Click here for a link to more photos of various styles of wine thief (barrel thief, glass whiskey thief, etc.).
