Batch Notes

Mash at 153F. I missed the initial temp and got 150F. I hooked up my heat exchanger and ran it for a bit, and the temp jumped to 170F, even with stirring. I added a couple of quarts of cold water, no change. Checked with a different thermometer, and got 151F. I've got to replace the thermometer on my mash tun. It stayed stuck at 170F for the duration. This happened last time I brewed too. So it looks like I started low, got to just about right, then cooled it down again. 150F will work, but this may be a little thinner than I was wanting.

Actual OG: 1.048

The hydrometer sample was excellent!

The yeast is from the ESB I brewed 2 weeks ago.

The hops are the experimental hops that I got on the hop tour this fall. They are a Fuggles derivative.

Nov 14: the airlock is bubbling nicely. I'm using the big fermenter in the garage since the outside temps are low enough.

Nov 26: Was going to rack to kegs today, but gravity was at 1.016.  I stirred up the yeast and will let it work a few more days.  I'd really like to get this down to about 1.012 or 1.011.
