I'm wondering if anyone has a web-based way to quickly find the alcohol content for comparisons of different wines. Of course you can always go into the store (in the US) and look it up on the bottle. Some of the individual vineyards describe this as well. But, it would be really nice to be able to cross-compare wines by percent alcohol, by maceration time, etc. In my own web searching I've not found any way to do this. Any suggestions?
We're curious about finding a good way to search on this since it has an influence on taste and there's research suggesting that the health effects of red wine are increased by low alcohol content and greater maceration time.
