First AG Batch: 65% Efficiency

[PvtSkippy]

I calibrated mine by just suspending them in boiling water and checking them temp... they should be 212 on the button... and then adjusted them accordingly to make sure they were.

Assuming you're close to sea level. I did the same thing, all happy that I found a reasonably accurate thermo-guessing tool only to remember (after the fact) that where I am water boils at 208 - 209F, depending on what the barometer says that day.

Good tip, do you have a good technique for calibrating? I have 3 therms and I think the floaty one might be off.

This is simple, but be sure to use the same thermo for everything, if you don't already. I made that mistake on my first AG, and my mash temp wound up being way to high.

Also, maybe consider going to a 1/2" copper manifold.

Brewed again last night: Ed's Bee Cave IPA. It went pretty well, I used the ph stabilizer and I think i crushed my grain finer (hard to tell with this corona+drill setup!), and ended up with 70% efficiency! Finally, some notion of improvement.
