Today I brewed a
Bavarian Weizen Hell using the maltase and high gravity process combined. This time I pulled out my 30l system after 4 small batches out of the Utility
Muffin Beer Research Kitchen.
6kg grains (50% Pilsener malt, 50% Wheat malt)
19l mash water
mash in: 4,5kg grains + 10l @ 69°C (156°F) -> 62°C (143°F), 40min
heating: -> 70°C (158°F), 15min
infusion: 9,0l 15°C (59°F) + 1,5kg grains -> 45°F (113°F), 45min
heating: -> 72°C (162°F) 30min
mash out: -> 78°C (172°F)
lautering with 15l sparging water
boiling: 70min
10g Hallertauer Perle (10a) @ t-70'
10g Hallertauer Perle (10a) @ t-10'
5g Hallertauer Perle (10a) @ flame out / whirlpool
Yeast: Fermentis SalAle WB-06
I expected 29l at 1,060 SG in the wort pan, but ended up with 27l. No big deal for me as I planned to dilute it anyway down to about 12°P.
Adding ~7l of water after boiling I ended at 11,8°P / 1,049 OG and 13 IBU.
Best guess, the grain-water-ratio mashing in was too low, but then I would have had some trouble getting down to 45° (113°F) with the infusion, at our actual cold water temperature from the tap. Next time I will try to prepare some ice blocks.
Why using the maltese process instead of just using sugar while boiling? It's about the challenge - and trying something new.
