I'm wanting to brew a 10 gal batch of pilsner and I'm not sure how much flavor and aroma hops I should use. The 5 gal recipe that I have calls for 1oz of each so would 2 oz each be good for a 10 gal batch? How much for a 15gal batch? The recipe calculator that I use gives me a pre-set AA% and when I change it to the actual AA% of the hops that I have it lets me know what the IBU's will be and I can adjust the weight of the addition to reach my target bitterness. If I adjust it for the actual AA% of the flavor and aroma hops the weight of the addition doesn't change and I have no way of knowing if it is enough. Can someone please help me Thanks, Mike
