Mudge:
What’s the difference between organic and biodynamic and regular wine? I know about organic tomatoes, but this is just confusing.
Not sure what any of this means

Dear Not Sure:
It is confusing, because organic for wine doesn’t mean the same thing that it means for vegetables or fruits. Organic wine is made without added sulfites, which is different from wine made with organic grapes. And biodynamic, like wines from Bonny Doon, takes organic farming to another level. And, interestingly, green wines are not as popular, relatively speaking, as other green products.

Dear Wine Curmudgeon:
I was at a dinner party the other night, and someone brought a bottle of wine because they liked the closure, which was some kind of screwcap. Do people really buy wine based on whether it has a screwcap? As opposed to how it tastes, because this wine tasted like gasoline.
You’ve got to be kidding

Dear Kidding:
I don’t know that anyone has done a study, but anecdotal evidence suggests just that. I recently had lunch with a 20-something woman who makes expensive wine in California, and she said that she will buy a screwcap wine, all things being equal, if she is in the store looking for a bottle for dinner. I have heard that many times, and I do it myself, too.

Dear Jeff:
I recently opened a bottle of wine, and the cork was kind of moldy. My husband said we should throw it out, that we would get some kind of disease. I hated to waste it, since it was an expensive bottle, and I am as cheap as you are. We did drink it, but I have been wondering: Was the wine OK to drink?
Worried about mold

Dear Worried:
You’re safe — mold on a wine cork is a sign the bottle has been stored properly, and is not like mold on bread, which you do want to throw out, regardless of how cheap you are. Typically, moldy corks will only happen to older and more expensive wines that people have been aging, and it’s not a problem with most of the wine we drink.

    The Wikipedia entry on wine closures notes several studies comparing screw caps and corks, the most notable being a 2007 study in Bordeaux that found that screw caps keep out oxygen better than natural or synthetic corks.
