Notes

Measured OG 1.050 FG 1.004
ABV: 6.04%
Added 2.5 jugs cold water to rinse grain (hence low efficiency)

Grain Bill and hop timings similar to Krush Centennial West Coast IPA brewed previously. This time with more hops.

Used 1 pack US-05 dry yeast + harvested yeast from previous brew.

Most hops used for a long time so should have plenty of flavour!
