Hey Paul, Nice tanks. I have some tanks as well, but I prefer to do my red primary fermentations in a bin. The height is actually only have the width. Great extraction. I was wondering if you employ punch downs or if you do pump overs. If you do punch downs, especially with ss punch down tools, I would be concerned with scratching the sides. Also you got those thermometers which you could easily damage the thermometer as well as the thermowells. Have you had these problems or concerns.
Occasionally it might scratch the sides a little but no harm. I do have to be careful with the 2 thermo wells one for the thermometer and the other for the cooling system.
But they are rugged and after a while you get used to missing them.
I usually do punch downs but sometimes I will do a pump over.
I get very good extraction. In fact this year I did not even use any additives for those purposes. The wine is very dark. What we call blood of the bull in Portugal.
I get a kind of submerged cap affect because of the shape of the tanks a substantial part of the cap is held down by its own weight.
Bins would be lower and I would not need a step stool BUT I have limited room so I opted to do it all in the tanks and so far I really like them.
I can cool things down when I want to and NOW I CAN HEAT too......
I found a company that sells these great outlet adapters with a temperature probe and a temperature dial. I plug it into a regular outlet then in true hammer fashion I hook a simple home depot snow gutter melting wire to that and wrap it around the tank. Bingo heat exactly where I want it and very little equipment cost. Best of all when I am done I take it away and store it in a small box.
My tanks are by far the best piece of equipment I purchased. Very flexible, can do big batches or small ones, cool or heat, ferment or store easy to rack, easy to clean I love them.
Oh and bonus….. They look great.
