I'm sitting here looking at the Brewing Classic Styles book, and I've decided that I'm going to try and make a recipe from each style. Right now I'm looking at making a Blonde Ale this weekend because it's the first style in the book that I have the ingredients for (sort of).
The recipe calls for .5 lbs of Crystal 15. I don't have it, and I know I can't just use half as much Crystal 30 (left over from my NG days) and kick in .25 lbs extra base to make up the difference...or could I since the Crystal 15 is only about 5% of the grain bill.
I guess what I'm asking is what is the best way of mixing Crystal malts to achieve what a recipe calls for?
