After a break of around 3 months I returned to the brewhouse aka the backroom of our garage. I dad a lot of cider available and no urge to go out in the cold to brew. It sould be fun.
A
Munich Dunkel was on the brewing schedule. I pulled out a former recipe the evening before and adjusted the hop varieties and quantities to the current stock. This time I hopped with Tettnanger, Tradition and Lilly, as I didn't have any Select to hand and I was also expecting a great profile from this combination. And by the way, I sent the obligatory two-liner to the customs office for the annual registration as a home brewer for 2025 - since this year, the home brew quantity has increased from 2 hectoliters to 5 hectoliters in Germany.
First of all, I steam-heated the fermenter while I weighed and milled the malts.
The brew day went very well overall - the heat-up times were a little longer than usual due to the significantly cooler ambient temperature, but on the other hand I've rarely cooled to below 20°C so quickly.
Finally I added the 5 litres of dilution from the fridge in the cellar and I had a pitching temperature of 14°C.
Before diluting, I had an original gravity of 15.3°P at 25 litres, an obvious measuring error then certified 11.8°P at 30 litres, mathematically it should be 12.8°P. However, I didn't want to open the fermenter again, so I only re-measured the undiluted fermentation sample, which confirmed the 1.062 OG.
Here's the recipe:
Code:
Munich Dunkel "Dünkl"
27l, 12.3°P, 25 IBU
5.0kg Munich I
0.2kg CaraAroma
0.2kg Melanoidin
14.0l + 5.5l mash water
14.0l sparge water
Mash in: 14.0l @ 57°C => 51°C for 10min
Infusion: 5.5l @ 98°C => 63°C for 30min
Decoct thick mash: 6.0l => heat to 72°C for 10min, then 10min to boiling temp => 72°C for 30min
Decoct thin mash: 5.0l => boil for 10 min => 77°C mash out
Boil for t-70min
15g Tettnanger (5.5a) + 15g Tradition (6.7a)+ 5g Lilly (7.5a) @ t-60min
10g Lilly (7.5a) @ t-0min / flameout whirlpool
2l chilled water for dilution (this time I used 5l)
20g MJ M-76 Bavarian Lager yeast
As I already mentioned, I ended up with a bit more liquor: 30l, 12.8°P and 23 IBU
