No problem using beer bottles. I bottle some of each wine I make in beer bottles. Usually a 6 pack. Partly to have a smaller portion for periodic tasting to check the wine's progress as it ages without using up a whole bottle. Also, so I have some smaller, 2-glass, servings for times when I don't want to open a full bottle. Sometimes I just want a couple glasses and don't expect to finish a bottle in the next day or two so I don't want to waste it.
