I'd appreciate that, thank you for the offer!
I just glanced over my recipe list and I have used it in lots of stuff: American Red Ale, Barleywine, English mild, ESB, Pumpkin Spiced Amber, Traditional Bock, and Winter Ale (my version of Arrogant Bastard).
I base most of my recipes on the ones found in "Brewing Classic Styles", making adjustments for my system and tastes. There are probably a few other recipes in that book that call for C120 that I haven't tried yet.
I think C120 is the only Crystal available to us that I don't yet have on hand. I have more than a whole sack of C60 if you'd like to swap for some of that or anything else you might need. I can do cash too if you prefer.
