2015-01-24	-1838	Brew Day Complete	1.073	11.5 Gallons	8/17/2018 9:08 PM	18.4 Brix, 11.5 gallons into fermenters. Strong caramel flavor profile, which should be perfect for style. A bit hop-forward for the style, but should mellow with age.
2015-02-07	-1824	Fermentation Complete	1.018		8/17/2018 9:08 PM	9.9 brix at racking. Forced carbed, but still a bit flat. Has nice maltiness/sweetness, but also enough bitterness to keep it from being cloying. Nice nuttiness and interesting dark fruit. Also, very thick mouth feel. Overall, quite happy with this and I think Kirk will like it.
2015-04-18	-1754	Tasting Note			8/17/2018 9:08 PM	Very good overall flavor typical of the style. Not as sweet as Kirk likes it but still quite good. Hop bitterNess is a bit too strong.

Notes

Standard BIAB infusion with mash out. 15.5 gallons strike water heated to 160.
