The results are in for our preference poll; it's been up for over 36 hours now, so I figure that's enough time to get a sample of something, at least.
Sam Adams Summer Ale - 7
Kronenbourg 1664 - 5
Smithwicks - 8
Bass Ale - 4
I think this implies that I should stick with Sam Summer Ale and thus stick it to the French; because Kronenbourg was such a late entry into the fold, the only way it would have received serious consideration was with a loud outcry of support from the masses. That did not materialize. It, unfortunately, ran a rather disorganized campaign and did not develop a very good ground game. (It should have emphasized its German roots rather than its French reality, I suppose.)
As for Smithwicks/Bass Ale: prior to the poll idea, I was going to do a blind taste test between the two and decide from there. But the Summer Ale/Smithwicks combo really does seem quite elegant, particularly because Smithwicks is a little darker than Bass. I think I'll still do the blind taste test if only for my own edification. (Plus blind taste tests are fun. Who doesn't like blind taste tests?)
