Hey guys! This would be my first post. Sadly I did not know about this forum, despite being a homebrewer for about 4 years. I was wondering if a 10gallon rubbermaid mash tun would fit a 20.5lb grain bill. Some have said "not doable", but others have said that if I use a water to grain ration of 1.25qt/lb, then it's doable. If decreasing the water to grain ratio is the only way to make it work, then how would decreasing the ratio affect the beer? Does a thicker mash decrease efficiency? Anyway, my big question is can I go "all-grain" or do I need to decrease the grain and supplement with DME or LME. Thanks!
