Wow, that took long enough... looking forward to your results.I recommend not ordering it from ibrew.com . I knew ordering from Australia could be dicey due to the distance - and it is.
Ok, I take back what I said - I got mine in the mail today. Gonna use it in the O-fest I'm brewing in a couple weeks, then on a German Pils. I'll definitely be posting the results.
On the shelf stability note, I usually drink my beers in about 4 weeks after kegging, so I'm not overly worried about oxidation. Rather, once they're tapped, it takes about 4 weeks to drink them. I usually give them 2-3 weeks to carbonate. But there is always room for improvement.
Yeah, definitely not gonna make any big pronouncements right away. It'll obviously take a while to judge shelf life. Not so long on beer quality. Can't help but think that if the macros justify spending $$ to use it, there must be some benefit. Time will tell.
