There's been a lot of talk on here about no-sparge brewing, following a recent Basic Brewing show and BYO article on the topic. (I heard the show but haven't read the article yet, since my gift subscription to BYO hasn't started.)
To take advantage of the enhanced malty flavor that no-sparge brewing is supposed to produce (particularly in session beers), this weekend I'm going to brew a 1.040 Blonde in a voile BIAB my wife just sewed for me. It won't be a pure no-sparge; due to mash tun limitations, I can't mash in my full pre-boil volume. So, I'm planning to dunk my grains in a little bit of water on the side and combine the runnings to hit volume. Even with this modification, my liquor to grist ratio will be much higher than normal, so I'm hopeful that I'll get improved flavor.
Here's my specific question: shooting for lower-than-normal efficiency, 65%-70%, I plan to up my grains a bit and only SINGLE crush (I normally double-crush for BIAB). Am I right about the single crush? Good idea? Bad idea?
