Farmhouse Rye Noir – Time for something a bit more funky after my last two brews, a Rye Black IPA with the NBS/Belle Saison yeast. I’m doing a 90min mash at 65c and will dry hop with 100g Galaxy pellets for a few days once finished fermenting. This recipe also uses up some bags of Special B, Extra Dark Crystal & CaraMunich III.
I’ve reduced the IBUs as I’m lead to believe this yeast can finish as low as 1002, thanks to @Kempicus & @ColinStronge, @MelissaCole & @100yojimbo. I also upped the Galaxy from 50g to 100g, with the warm/hot ferment I dare say a few volatiles will be gassed off.

Fermentables:
Pale Malt – 74.8%
Rye Malt – 14.4%
Special B – 5.6%
Carafa Special III (Weyermann) – 2.2%
Crystal Malt, ExtraDark – 1.5%
Cara Munich III (Weyermann) – 1.5%

Hops:
Topaz Whole – 17.2 % @ 60 mins – 10g (FWH)
Topaz Whole – 17.2 % @ 10 mins – 50g
Galaxy Whole – 15.0 % @ 0 mins – 100g
Galaxy Pellet – 12.5 % @ 0 mins – 100g (Dry Hop in FV)

Final Volume: 25 Litres
Original Gravity: 1.062
Final Gravity: 1.016
Alcohol Content: 6% ABV
Mash Efficiency: 75 %
Bitterness: 44 EBU (16EBU ignoring the 10mins Topaz)
Colour: 125 EBC
Mash: 65c for 90mins

The wort had a good look to it as the break material settled with a nice sheen of hop oil from the Galaxy, fingers crossed the beer will be a good one too.

*28th Aug ’13 – Gravity at 1016.5 and temp at 25°c, in the fridge now set to warm to 28°c.

*29th Aug ’13 – Gravity at 1007 @30°c it looks to have finished fermenting, I have added 100g of Galaxy pellets and will give it a rouse tomorrow.

*5th Sep ’13 – I was supposed to bottle this today, oh well… its tasting better now 🙂

*Bottled 7th Sep ’13 – with 122g white sugar

*25th Sep ’13 – Tasting this again, the sort of nuttiness that it had has gone and it tastes alright, I can’t distinguish any one part but its crisp and pretty light & refreshing.

*BTW…. This turned out to be 7.2% ABV 😉 Having a bottle now, its mostly yeast character and the dry hopping feels to have been a bit wasted, not that I’m too bothered as it drinks well.

After supping some of Leedsbrew’s Smoked Stout yesterday I decided I’d better use my kilo of Rauchmalt today, then I can justify buying some Peat Smoked malt 😉

Kartoffel-Rauch (Potato Smoke)

Fermentables:

Hops:

Hallertauer Hersbrucker @ 10 mins – 25g

Final Gravity: 1.012
