Grey Skies Porter

A classic English style, which at one time almost disappeared from the brewing world, was just too delicious to vanish. Utilizing black and chocolate malts instead of roasted barley brings forward a sharp bitterness that mingles with malty sweetness that is most desired in porters. Brew this beer in the beginning of February and enjoy it later the same month.

    Description of this Beer:
    Balanced, roasty, and delicious. This beer was designed to be similar to Deschutes's Black Butte Porter, but with "more character." This recipe is fine with slightly more or less bitterness or with slightly less base malt. I have begun experimenting with different yeasts as well - I think it's an all-around great porter recipe to mess around with.
