I was wondering how much time I should be taking to get the runnings from the mash. I batch sparge and make 5 gallon batches. I haven't really timed it, but I guess it takes me 15 minutes apiece on the first and second runnings, maybe less. Is that too quick? Usually I'm itching to get on with boiling by the time I have my second runnings draining. I've only had one stuck mash in about 3 years of all-grain brewing. Does going slow provide any benefits other than reducing the chances of stuck mashes?
