I have used this site for the first time and loaded a recipe in that I am going to try once my other is done and I see whether I got it right or not. I like that the site tells you how much mash water, how much sparge water and how much total capacity you will have from the grains and the mash water in Gallons. I know for you guys this is easy to figure out, but for me I am liking it because I know whether I can use my 5 gallon pot or I have to break out my new stuff for a smaller batch. I am still learning the other stuff, ie apv, color, and stuff like that. It seems like a pretty good tool for me to use at least to start with. RR
