It's a rolling but gentle boil. I think the design of the pot also helps (as it's tall and not a lot of exposed surface area).
I'll try the foil idea. Thanks!
Thanks for the thoughts. I did do trial runs and calculated 0.2 gal dead space loss and 0.5 gal/hour evap loss, both of which were plugged into BeerSmith.
I understand from Palmer that having too much "head space" in the mash tun decreases efficiency, but I don't really want to go smaller...
I am taking gravity readings with a refractomerter. I placed the wort into a ceramic mug to cool down for 5 minutes to ambient temp (70 F) then took the readings.
I am in need of help with my efficiency. I've read previous threads, took the advice, but am still having nightmare-ish efficiency problems. So far, I have done 2 all grain batches after a dozen or so extract brews.
My equipment:
I have a five gallon circular cooler from Home Depot that I...
You're right on--I have no idea what the temps are! I just know my basement is cooler than the rest of my house, which we keep at 66. I like idea of bringing to brewery. Might just do that.
I think this wasn't a problem. I only have done 1-2 gallon batches, and I have used half of the packets (or a little more) after rehydrating. But something to be aware of as well.
If he refunds you the money that you paid him, you really have no "damages" to speak of (minus minute interest/opportunity costs). Take the money and walk away.
