So I now have my BrewTree set up with 4 burners, and 2 pumps. I can do 2 batches almost at the same time now with the 2 boiler tiers. As soon as the mash is done for the first batch I have the second batch doughed in usually before the first batch is boiling. With a 30 whirlpool for hop additions on the first batch last weekend I did 2 batches start to finish including cleanup in 6 hours. I was able to whirlpool the first batch for the extra 45 minutes while I was boiling the second batch, then crash them and one after another and transfer to fermenters. I love this stand it has shaved so much time of my brew day! I now have about $1200 wrapped up in the brewtree, and I will try to post a few pics of the newest system.
