I don't consume any alcohol and want to find substitutions for recipes calling for it.

I've seen the substitution charts for the corresponding extracts, vinegars, and concentrates (e.g. http://whatscookingamerica.net/alcoholsub.htm).

But I'm confused at how much to add of suggested substitutions.

How would you guys substitute 1 cup of:

- Wine
- Beer
- Brandy
- Cognac
- Bourbon
- Tequila
- Any other common alcohol used in cooking you can think of

Thanks!
