Notes

Friday 9/22/2017

Steeped the two varieties of grains and the roasted barley (4.2oz of each) for 30 minutes

Flame out part way through - no thermometer so i turned the flame on and off so as not to scorch

Removed grain

Added

1oz Cascade 7.1 AA<br />
1oz East Kent Golding 5.6 AA<br />

Set timer for 30min

About 7.5min to go – added 1oz East Kent Golding 5.6 AA

In a side pot – transferred some wort and dissolved 1lb DME and 0.5 lb sugar.

At end of timer, flame off and transferred side pot to main pot, removed hops, began cold crash.

I added two packs of dry Safale US-05 right into the fermenter - no rehydration.

The wort (pre-yeast) tasted amazing. Pretty sweet but thats to be expected at this point in the process. Has a good strong coffee taste to it.

Tuesday 9/26/2017 - Didn't notice much of any fermentation happening so I took a gravity reading and to my surprise, it was down to a little over 1.030 from a start of 1.090! It still tasted pretty sweet and I feel like the coffee taste has diminished somewhat.

There seemed to be stuff collecting at the bottom - not sure if it was dead yeast or what but I decided to stir things up a bit - literally. Then I re-hydrated about half a packet of Safale US-05 and poured that into the fermenter. Let's see what happens.
