AG#4 Old thumper clone. Wanted to brew a stronger darker ale. This brew is based on the recipe in Graham Wheeler's book, but with a few modifications.


malt Ingredients - Pale malt with the salts on top. The other malts are in the bucket below the pale malt

Mashing with my HERMS system. I've changed my brewing kit to include a Heat
Exchanged Recirculating Mash System (HERMS). The smaller vessel in the background is the heat exchanger. The wort is pumped through the heat exchanger which is controlled by a PID.   As you can see I have a "G" clamp holding the return manifold in place - more refinement required!

boil This is the PID controller for the heat exchanger. This is the prototype and hopefully I will enclose the system in a more appropriate container in the future
Sample - one advantage of using the HERMS system is that the wort should be clearer. As the wort is recirculated it uses the grain bed as a filter and hence the wort should be clearer. Not in this case!!! Need to do some more brews to perfect the system
Running into FV I've made a new larger Immersion Cooler that fits better into my copper. The original IC is now the heat exchanger for the HERMS system.
Racking the beer into barrel. Bought a new king keg barrel as not sure the budget barrel was holding pressure well enough. Also bought a new cap for the budget barrel so it may be OK now.
