I've done a pound per 5 gallon batch several times. It works, kind of.
It's hop dependent, kind of, oddly enough, in my experience.
Simcoe, yes, every time.
Cascade. Nope, nope, nope.
My schedule:
1 oz @20
1 oz @15
1 oz @10
1 oz @5
8 oz whirlpool @150°
2 oz dry hop for 6 days ---- add these hops during second day of active fermentation
2 oz dry hop for 3 days
OG should be in the 1.065-1.075 range. Simcoe can handle some crystal malt in the grain bill, but the cascade just didn't put up enough of a front end to handle the same grain bill. I would suggest thinking about how assertive the planned hop is when formulating your grain bill. Something like cascade could work, but it would probably only work in these quantities with nothing darker/sweeter than a toasted malt, unless you moved some of the hops to a bittering addition. You really need a substantial amount of IBUs.
