I'm in the planning stages of doing a SMaSH with some Pale 2 Row grain I got from a local grower here in Massachusetts. I usually mash at 1.25 qt but have noticed that the Brewers Friend app has been pre-selecting 1.5. I saw a poll from 2016 on here where the top two measurements people choose were 1.25 and 1.5. How much difference does mash thickness make in efficiency? I know it depends on the malts being used, but not much else. What measurement do you utilize for mash thickness? Lets get a good conversation started!!
