I just picked up this dry hopper (http://www.stainlessbrewing.com/Dry-Hopper-with-twist-cap_p_155.html) and am about to give it it's first use in an APA/Session IPA. I've always used a secondary for dry-hopping and removed the beer from the hops after a week or so. My question is if I leave the dry hopper in the keg will I eventually get a negative effect from having the hops in too long?
I'm also toying with the idea of throwing some mangos or some other fruit in the dry hopper. So, same question - do you think leaving the fruit in the keg would eventually be a bad call? I'm wondering if it would eventually begin to rot.
Thanks!
That's the one I have. As for the hops, I leave them in. You'll just have to experiment to see what you like - brewers here like dry hopping at all sorts of time increments (and temps). I used to dry hop in secondary for a week, then keg. I haven't found much difference in leaving them in, since I put the keg in the fridge after a week of dry hopping @ room temp (though some extraction does occur at colder temps, and sometimes with different character). But many others perceive a grassiness with long extraction. Regardless, the cool thing with the canister is that you can easily pull it whenever the flavor is where YOU want. As for the fruit, I usually use purees in secondary before kegging.
EDIT - The concern with the fruit in the canister wouldn't be in rotting (low pH and alcohol present would keep that in check), but depending on the yeast strain you used and your serving temp, there could be additional fermentation leading to excessive carbonation in a keg that sat for awhile. If it were a keg that were only gonna last a couple weeks, you'd probably be fine.
EDIT 2 - I did use the canister with fresh fruit in it once (come to think of it) before I switched to purees for good. And it came out fine - but like I said, the keg went very quickly, ~ 7 -10 days. I don't remember it seeming over carbed before it kicked. It may well have gotten that way with more time.
