Session Baltic Porter

I like porters. I really like Sinebrychoff. And it's cold out now, so I've been jonesing for dark and malty beers pretty hard lately. But I'm also looking for more session-strength beers so I can keep drinking, rather than being knocked out after a bottle or two of high-octane stuff. So here we are.

Lower-gravity English porters are fantastic, but I wondered what a scaled-down Baltic porter would be like. With session beers, I try to stick to a few of Mike Tonsmiere's basic guidelines to preserve flavor in a smaller package:

 - Use more characterful base malts
 - Use a higher percentage of character malts
 - Aim for a higher saccharification rest temperature
 - Select a less attenuative, more expressive yeast strain

First three items: check. While the Wyeast German Ale strain doesn't really fit Parameter 4, it should keep the finished beer a bit more lager like, in the style of the original. Bring on the little big beer.
