Tell me if I have the concept right. (Although in practicality I suppose it won't make much difference.)
I'm using a 5-gallon batch recipe to make a 2-gallon batch of Cream Ale. The recipe calls for 1 oz. of Cluster hops at 8.0% Alpha Acid. My store doesn't carry Cluster so I got Northern Brewer at 9.5%.
Of course, I could *also* figure: The 1 oz to 5 gallons were probably determined for convenient measuring. This hop is roughly 1/8 stronger, I'll use roughly 1/8 less if it's convenient for measuring. Otherwise they are close enough. 2/5 of 1 oz is .4 oz but it's convenient on my scale to round that to 3/8 (.375) oz... and that's a bit less so it'll do.
But am I correct in the concept? You adjust your amount for the acid percentage? Right?

So in *theory* I figure 1 oz. at 8.0% = x oz. at 9.5 percent. Solve for x to get x = 8.5/9.5 = 17/19. Multiply x by 2/5 to get .36 oz but I can figure that's close to 3/8 oz (.375).
