Recently I experimented with the acid malt in one of my stout recipes and purposely used a little extra to find out what it would change. It is clear that the finished product has a "twang" or acidic taste to it by adding only a couple extra ounces to an 11 gallon batch.
I am circulating at the same time while firing the MLT. I have a high output burner below it but I can throttle this down as low as needed. I do have a temp sensor on the outlet of the MLT as well. What temp should I be afraid at this point to avoid?
I will give this a go for my next brew day. I usually throw a 20lb bag in as well. I like the idea of not returning the hot water right away as well to save some of the cooling capacity and expelling this water for cleanup.
I do have another question that came up this week during my brew...
What size batches are you cooling using this configuration? With a ten gallon batch I suspect that the ice will be nearly all gone in 5 minutes once I reach 120°ish.
Do you completely fill your HLT with ice? I would rather not spend another $10 per batch on ice but instead use the ice i have...
55° - 60°. Once I hit about 110° circulating the water from the HLT I then switch over and circulate tap water through the boil kettle to get the rest of the way down to 70°. This is painfully slow and inefficient.
I have done a second brew day and have now come to the conclusion I am not getting enough cooling capacity out of this double circulating method. I have put a very large bag of ice into the HLT and filled it with water. The hot wort circulates through the HLT and the cold water through the...
Thanks guys for the compliments. I plan to post a few more pics on a seperate thread but just wanted to put one up here to give Boerderij his due credit.

this is an amazing design. I have spent many hours studying and building what you are showing in your designs with a few alterations. I am finally going to do my first all grain brew day this weekend and am laying out what my steps will be. How would I go about opening your process...
