Ok I have gotten back into brewing from a 4 year layoff. I have my return beer in the bottles just waiting for them to finish. I am going to be doing a partial mash brown ale next. My question is that I want to see what you guys think I need to do first. My two options are 1. build a fermentation chamber or 2 build a mash tun from the 10 gallon rubbermaid I have sitting here. I got a $50 gift to Home Depot that I want to use. So what do you guys think I should go for first?
