Schwarz IPA – My first Black IPA, at 4% ABV with a healthy bitterness of 62 EBU, not quite a Hop-bomb but 150g of 80c steep hops should be enough following the bittering addition at 35mins (25mins after boil start).
My recipe takes a few things into account; some pre-weighed and mixed Pacific Gem & Magnum; the end of a sack of Pale malt; Part bags of Carafa Spesh III & Cara Aroma; Open bags of Hops.
A screwed up beer, its a German Hopped Black India Pale Ale… Nice 🙂

Pale Malt – 19.5%
Carafa Special III – 5%
Wheat Malt – 5%

Hops:
Pacific Gem – 14.6 % @ 35 mins – 24g
Magnum – 14.5 % @ 35 mins – 24g
Hallertauer Mittlefruh – 4.2 % @ 0 mins – 53g (80c Steep for 30mins)
Magnum – 14.5 % @ 0 mins – 48g (80c Steep for 30mins)
Hallertauer Hersbrucker – 3.0 % @ 0 mins – 49g (80c Steep for 30mins)

Dry Hops:
Tettnang – 50g
Crystal hops – 50g

The malts and temp:

Today’s hopping, Bittering from Pacific Gem & Magnum, 80c Steep from Hersbrucker; Magnum & Mittlefruh:

I recircuated about 6 litres to get a good clear flow of wort:

Boiling away nicely:

Bittering hops going in:

150g of 80c Steep hops:

Got 89% Mash Efficiency, hit a few points over my target OG after the boil and liquored back to 1042 with Hydrometer reading (1039 with Refractometer) I’m not sure which I trust.
I’m starting to get a better feel for the new mash tun and can cope with having to add 2.5 Litres of cooled boiled liquor after the boil 🙂

*16th July ’11 Gravity @ 1010 and looks like its done. Tasting interesting, bitterness coming through and roasty finish. I’ve decided on dry Hopping with 50g Tettnang & 50g Crystal hops, moving away slightly from the German theme with the Crystal but it does have some German Mittlefruh parentage.

*Bottled 24th Jul ’11 with 70g White Sugar, dry hopping probably kept hold of 1-2 Litres of beer, tastes a bit grassy for my liking maybe it will take a few weeks to settle down.
