2013 Altbier

Not sure where February went. And now March is almost half over too. Luckily, I managed to find some time today to brew up this year's Altbier...a bit later than I wanted to, but better late than never.

Last year's Altbier was really quite nice...easily my best one yet. However, I felt like it needed a few things. First, it didn't have the head I thought it should have, so this time I added a protein rest to perhaps help with that. Second, I replaced the pale ale malt with more Pilsner malt, and added some Caramunich after reading some info by Kai Troester about the use of crystal malt in this style. Lastly, and this is the place I debated about the most, I went with a single hop addition of Spalter hops, giving me only approximately 30 estimated IBUs. I think this is a more traditional hopping schedule, even though the IBUs fall outside the BJCP style guidelines.

Last year I opted not to lager this beer. This year, I may not have the choice as the coolest ambient temperatures may already climb into the 50s by the time this is done fermenting (I rely completely on the various ambient temperatures of my garage and cellar, which is why I try to brew this beer earlier in the winter, when I'm reasonably certain to have cool enough temperatures).
