v3 difference - added 1 lb Caramel 20, added 1 oz Mt Hood at 30 min., substituted 0.5 oz Mt Hood at 15 min. for 1 oz Perle. Also, .5 Perle and .5 oz German Select was used at 60 min due to lack of Perle in stock. Actually brewed a 10 gallon batch, but cut the recipe in half for 5 gal. reference. That's why you see my "unusual" hop schedule.
