We used a Heineken for its crispness, color and light flavor. Lagers and other German style beers are other good options, too. If you want the flavor to be more beer-forward, choose an IPA or another hoppy style pale-ale. You can even use dark beers like stouts and porters, if you don't mind a darker color and prominent beer flavor. Just stay away from sour beers, or any beer with a fruity tasting profile.
