Questions, the tub with the wort in it. What part of the process are you in? and how does using the rubbermaid tub help. Is it because of the size of your batch?
The stage we are in is the collection of wort from the mashtun.
And, you are correct. We only used the rubbermaid because of the great volume we collected: 20+ gallons which we split into two 10 gallon batches of equal SG.
