I plan to brew JZ's ESB. It calls for crystal 15L. Where can I get that? I checked Austin home brew and northern brewer. They don't carry it. If I can't get it should I use the 10 or 20? Or some other specialty grain?
Northern Brewer carries British Crystal Malt 15L. I don't see it on the internet, but I know they carry it in the St. Paul store. I believe it is a Simpson's product
