Just brewed this up yesterday. Checked on fermentation today and it smells great. One of the most aromatic beers I have smelled that isn't hop related.
Also, a side note, the book on sacred healing beers has a great section on yarrow and the use of it.
Brewing in Alaska!
Bottled: Pomegranate Orange Witbier, Yule Gruit, English ESB, 7 Grain Black Chocolate Stout, Oaked Bourbon Vanilla Imperial Porter
