Extratasty is user submitted drink recipes meets tagging meets social networking. (The social networking is coming soon.)

Michael Arrington says:

Users submit drink recipes. Ingredients are tagged and searchable. Drink recipes are ratable. There is an option to include all of the things you have in your bar, and the site will tell you what drinks are possible in different combinations.

Here's a link for all the German readers.

From the people who brought us Threadless (skinnycorp); now brings us Extratasty.com. This is a pretty new site, so it's doesn't have every drink recipe yet; but it will soon. If you have a great drink and don't mind sharing the recipe or if you're looking for something new to mix with that bottle of Grey Goose laying around the house. Then head on over to Extratasty.com.

Ari Paparo says:

Extratasty is a "Web 2.0" site that lets you search and tag your favorite alcoholic drink recipes. Which means that it's easy to use, has high quality design, and uses "tags" as a form of navigation.

This is something I might have used a bit more a few years back. Thus, it'll probably be big with the college crowd. If anything, I'd probably use this to get rid of some remnant bottles of alcohol. But, I expect big things, nonetheless. Skinnycorp rewrote the rules of t-shirt commerce and social networking with Threadless. And I'll toast to that!
