Guys - My Riwaka heavy beer is starting to smell like Riwaka. I'm so happy I could almost cry, but I'm going to see how it progresses from here.
For those following my troubles, the two things I changed this go around was giving a bit more time at stable FG before moving forward with dry-hop, and absolutely effing NUKING my kegs with a cleaning procedure. I hit them with PBW and boiling water this time, followed by Iodophor (I've never used it), followed by SaniClean. (I think it was the kegs, personally....)
So far, no odd pencil-shaving, ambiguous aroma on this batch. Things are looking up, but I don't want to count my eggs just yet.
@Dgallo - I just received my second fermenting keg from Bobby @ BrewHardware. Same mods as my first one, with a welded 2" ferrule and thermowell. I'll experiment with my next NE batch with dry-hopping in a second keg with agitation.
Thanks all for listening to me moan about sucking at home and not at the brewery. Keep them fingers crossed for me, but I might be back in the game.
edit - I think it's appropriate to send a shoutout to
@Bobby_M @ BrewHardware. This guy is a stalwart in the community, and if anyone is looking for custom work, ingredients or anything homebrew, and you usually order online, give him a look/shot. The guy really cares and the shop is excellent.
