Samples off the tank, even after cold conditioned for sediment to drop out, are a bit harsh and astringent. Can’t figure out where this coming from.
10 gallon batch
8% abv
1.078 -> 1.018
51% 2 row
38% Oat malt
6% Table sugar
5% Maltodextrin
Magnum FW hops 15 IBU
Galaxy, Citra 20 min for 42 IBU
Galaxy, Citra WP 20 min for 21 IBU
LAIII Yeast at 65F, sugars were added in doses for 3 days at high krausen
Water profile using filtered water with low TDS (30 ppm) with salts added (gypsum, CaCl, epsom salt)
108 Ca, 11 Mg, 101 SO4, 147 Cl
I acidified water with some fresh citrus juice:
100ml grapefruit and orange juice to acidify strike and sparge water to pH 6.0
Mash pH initially a bit low at 4.8 so had to add 15g NaHCO3 to mash to bring to 5.2pH. Added 57 Na, 143 HCO3.
Sparged with 160F water pH 5.8 and runoff was about 1.020 when I reached boil volume.
Hazy DIPA with around 80 estimated IBU. It’s been a while since I went higher IBU like this but am doing so after hearing Tree House recommendations.
Any idea why getting this astringent bitterness? Haven’t even added dry hops yet. Thanks.
