(craft beer) "... is just about $27 per gallon, which would make a five gallon batch about 110 bucks..."
$15 per sixer of 12oz bottles is pretty steep too.
OK, my arithmatic was under the influence!
But as far as the $15 being steep, I was specifically talking about the beer we were making that day, a Belgian Holiday Ale, and the $27/gallon figure was actually low. Anyway, we start our Shop Brews at 8 am, and we'd already been sampling some similar (> 9% ABV) brews, so my little grey cells were at a slight disadvantage
Back to the topic, the heart of the grist gun is a flower bulb auger, available online for $20 or less. About $5 in ABS (and one PVC) parts, and I made the stand with less than half a sheet of plywood. If anybody wants I can email the NHC session Powerpoint, just shoot me an email: firstname.lastname@example.org
Mounting your mill above the MLT may work for some of you, but it wasn't an option for the Club system. We brew at our host LHBS, and use the Shop's mill ( a Crank and Stein 328D). So we crush, put the grist in empty 25kg malt bags, and take it out to the brew rig. The Grist Gun neatly sits on top of the boil kettle, we dough in, and then it gets put in the Club House til the next brew. (edited for spelling email addy)
