Final E-brewery upgrades

The final upgrades to my electric brewery are complete. I added a 25′ x 3/8″ HERMs coil to my hot liquor tank (HLT) this weekend and got a chance to test it out today on my 11 gal historical 1868 English Porter brew. The coil allows me to hold mash temps steady throughout the whole mash by pumping wort thru the coil – the electronic temp control in my HLT allows me to set whatever temp I want the HLT water and mash to stay at. I can also do step mashes now too, so I can add a protein rest to my wheat or pilsner brews, and also use the HERMs to raise the mash temp to 168 for mashout. Here’s what the coil looks like:

I do like the fact that I can bring the mash up to 168 for mashout – it seemed to improve my efficiency as I got 86% efficiency in this batch – the best I’ve ever gotten.

The other new add-on to my brewery is the $10 stainless steel hop stopper I added to my boil kettle. It’s made from a jumbo stainless steel tea ball from Amazon. I used a small phillips screwdriver to force a hole in the side of the tea ball, and then stretched out the hole until it was large enough to fit my side pickup tube thru. Then I cut about 1.5 inches off my pickup tube so the hop ball would fit in along the side of the kettle, and also cut some grooves into the end of the tube. If the open end of the tube get pressed up against the side of the stainless screen and some hops block the screen, the wort will still be able to drain into the tube thru the grooves. Here’s picture of it before the brew:

Here’s the grooves I cut into the pickup tube:

Here’s what it looks like after a brew that used 5oz of leaf hops. It drained all 11 gal out quickly with no hops getting into the fermentor or plugging up at all.

I haven’t tried it with hop pellets yet, but I don’t normally have a problem with pellets hops plugging up my pickup tube like whole hops do.

Overall I am very happy with the hop stopper, it only took a few minutes to build and it works as well as a $60 hopstopper you can buy online. Plus it’s stainless so it should last forever. If you use whole hops and need to keep your pickup tube from plugging – build one yourself!

EDIT: Here’s a link to my HBT thread about this, along with more pictures.
