Notes

Batch # 2 - 1/8/21 (Eff.: 60%, Att.: %, ABV: %)

  • Mash vol.: 32.5 L, Pre-boil vol.: 27 L, Batch vol.: 21 L
  • US-05 (2x yeast packs dry pitched)
    OG: 1082 (Refract.) 10 (Tilt)
    Volume at boil was 27 rather than expected 28 L.
    Dark grains not cold steeped for this batch, added late to the mash instead.
    2/8/21 - SG: 1079
    6/8/21 - SG: 1024
    7/8/21 - SG: 1018 ferm temp upped slowly to 20 C.
    12/8/21 - SG: 1015, chilled 10 C added 1 split soaked vanilla bean.
    15/8/21 - Added 100g of whole coffee beans, Evolve house blend
    22/8/21 - Kegged and carbed, only had time to cold crash for a few hours.
    3/9/21 - Made for Andi's long table dinner which was cancelled, the boys at Evolve liked it. The coffee isn't as big as previous, 100g of whole beans seems to be pretty spot on for a nice background flavour.

    Batch #1 - 3/5/21 (Eff.: 58%, Att.: 81%, ABV: 8.1%)
  • Mash vol.: 32.5 L, Pre-boil vol.: 28 L, Batch vol.: 22 L
