Brewer's Comments:
My ginger wit is bottled and tastes great. It is a wonderfully
refreshing summer cooler that even non-beer drinkers seem to like.
The ginger is present but not "in your face," and the orangey
coriander makes it recognizably a wit. The cardamom and grain of
paradise are at present subliminal, as are the flavor and aroma hops.
I expect it to evolve further.
I substituted ginger for the more traditional bitter orange peal, but
I feel that this is a variable style where "traditional" is hard to
pin down, and this kind of recipe is in keeping with the spirit of
tradition. The subtle ginger "bite" seems to substitute nicely for
the omitted lactic acidity. At 19 days from mash to mouth, there's
still time to brew and enjoy this summer!
