Red Wine vs Beer

[Tyrrell]

I don't know the answer to your question but I've got some thoughts.

Both dry Wine and Beer I imagine derive the great majority of their calories from alcohol (wines with a lot of sugar may be different).

Wine has more alcohol per volume than beer so I would think that it has more calories per volume than beer.

People tend to drink greater volumes of beer than they do wine.

It seems to me that if they are consumed in the same manner it would be a wash. (Not to imply that they should be consumed in the same manner.)

Caloric values for wine and beer must be pretty simple to google for. Also, one of the regulars on this board is a doctor who probably will have something enlightening to say.
