Lots of the small breweries around here sell home brew supplies. Sounds like a generalization. Some breweries have even offered me grains at wholesale prices.
Keg condition or bottle condition? I'm assuming bottle conditioned. The ride shouldn't shake them up more than it would commercial beer, and letting them sit for a few hours in ice is probably a smart idea regardless.
I assume this is due to sediment that sits below the dip tube. I also assume you purge the empty keg before filling. I like this idea and might try it if I bring some beer home for the holidays.
Stuck my hand in cooled wart to unblock my false bottom only to have a friend remind me I could syphon. Beer turned out fine til the keg faucet opened up and dumped all the beer into the chest freezer. It tasted good off the floor though.
An annoying repose I got was "can I try your beer ". I love sharing and explained it's a very bitter ipa (maybe 70 ibu-not that bitter). Everyone still seemed enthused so I poured a few pints. After taking a sip they all admitted to not liking IPAs as a style. I said they didn't need to finish...
The problem I see is your bittering hops will be simcoe. I don't know about your area but simcoe is more expensive here and I'd hate to waste it in a beer that I couldn't taste it.
If I were to do it I'd bitter with 1-2 oz simcoe and use an oz of cascade at 15 and one oz cascade at 0. Haven't...
If it were me I might add a second oz of bittering hops. I enjoy very bitter IPAs and that's a larger grain bill.
Not sure what the A% of summit is, but I usually bitter with 2 oz of magnum or columbus.
Sorry that I jumped to conclusions! It's great to be reminded women enjoy brewing beer too!
Cheers,
Peter
Edit: I guess I probably could have guessed that had I paid attention to your name :)
