I have time for one more beer before I start making my NHC 2015 beers. Not much time so I figured I’d make an English style beer that is a bit quicker turn around and one I have haven’t brewed before. After kicking it around a bit I settled on a Brown Porter for no real good reason other than I’ve brewed most of the other English low gravity styles.
I did my normal research and reread the Porter book from the Classic Styles series, Brewing Classic Styles and old NHC recipes. Jamil’s recipe seemed like a good place to start so I took his recipe and tweaked it a bit. In reading the BJCP style guide it mentions low roast and chocolate and possibly some coffee notes. I find most chocolate malt to be a bit harsh (acrid/astringent) so I decided to take Jamil’s chocolate and split it half and half as pale chocolate and coffee malt. Also, I find fuggles to be a bit too earthy / woody so I used Willamette instead which I really like. Otherwise I basically stuck with his recipe.

14 lb of grain
1.5 qt/lb = 21 quarts = 5.25 gallons

mash in water temp 162.1 so 162.1 into mash tun and measure before mashing in

8/25/14 Fairly normal Brewday. 80F and sunny out which is always nice 🙂 Efficiency was super high (84%) so I had to dilute my work with 1G of water to get the gravity right. pH was a bit high but not way off. I measured water temp in MLT pre-mashing in and it was spot on it looks like Mash temp was good. Cooled wort to 65 but it was 69 by the time I pitched. Not a big deal but I was aiming for 66 at pitching time. Pitched 1.3L starter. Set the brewpi to drop 1 degree F over 24 ours and hold at 68 through end of primary.
8/26/14 @ 8am 1 inch kreusen and VERY active fermentation.
8/27/14 @ 8am yesterday afternoon ferment was ferocious! amazingly no blowoff. this morning ferment still steady but seems to have slowed
8/28/14 @ 8am wow, kreusen totally dropped and zero bubbling. definitely my fastest ferment ever. hopefully it has finished out.
