I realize this is an old thread, but I recently opened a Scottish 80 that I made with Fuggles and northern brewer's hopshot extract. 5 gallon batch, 90 minute boil. Bottled for 3 months in a 50 degree cellar. Was 1.056 OG and a 1.020 FG.
I used 1oz Fuggles @ 60 min -- but then used 2oz hopshot @20 min and 1oz hopshot at 5 min.
My god. What a spicy result. In fact, it's overwhelmingly spicy. It's too much -- nearly all spice, very little malt. It's a shame, because I'd hoped for a bit more balance.
Anyway, lesson learned: (a) Hopshot is fine for bittering, but I'll never again use it for flavor or aroma additions and (b) I wish they'd come out with an extract that instead of spicy has the citrus/piney flavor common to American IPAs. (Is Hopshot super concentrated Warrior?)
