I'm making the T'ej recipe from Calagione's "Extreme Brewing" book, my first attempt at mead or its cousins. The recipe calls for shredded gesho, but the only gesho I could find is the whole sticks. The recipe calls for 9.6 oz. Since shredded roots would have much more surface area than the whole sticks, should I increase the amount I use? (I have a pound) Is there a reasonable way to shred the sticks or am I better off using them whole? And if I'm using whole sticks, should I boil them for 15 minutes like the recipe says or longer? Thanks!
