<<Disclaimer: Verify this information before applying it to your situation.>> Seeing several posts regarding wine in the past week and wanted to add my 2 cents. I work for a small family owned "boutique" winery in California and have been studying and traveling for wine for over 10 years. While I am not a winemaker where I work, I am a home winemaker. [My job is marketing, PR and sales]. I drink wine daily and typically purchase wines from small family owned places rather than the big corporations [those that are typically distributed throughout the states]. I am by no means an expert in how all wines are made, but wanted to share my experiences. Wines that are fortified (some California "Ports" for instance) may have "high proof" added which can be grain based. It is supposed to be grape based, but there's always that chance. [I personally stay away from port and all fortified wines.] When a particular wine requires fining, many wineries use either bentonite or egg whites as the fining agent. Many wineries don't fine but filter their wines. I did a quick survey of some of the local wineries and no one used any gluten containing products in their wines. HOWEVER! I did find out that manufacturers of wine barrels will occassionally use flour to seal up tiny gaps between the barrel staves... sort of like using talcum powder on a squeaky wood floor. The winemaker where I work said he has on occassion used a small amount of flour mixed with water as a glue on his barrels. Now, a barrel will hold about 25 cases of wine. That's 300 bottles or 1800 glasses of wine for about a tablespoon of flour. A winery may have 2 or 200 or even 2,000 barrels of the same wine. Before it's all bottled, it usually is mixed together in a tank so all the wine is consistent. So that tablespoon of flour could be distributed among many many more cases than just the one barrel. Everyone must make their own decisions regarding their health and what they will eat and drink. For me, I will continue to enjoy wine. * Please carefully compose your subject lines in all posts * Archives are at: Http://Listserv.icors.org/SCRIPTS/WA-ICORS.EXE?LIST=CELIAC
