Some vinegar, yeah - but something else. That distinct "jar of olives" aroma. It's quite substantial. Not grapefruity at all.
It's in a bucket so I don't have good access, but I got a peek (but no picture) this morning when I swapped out the blowoff tube for an airlock. The krausen is big and fluffy - looks perfectly normal.
This is wyeast 1056 and I've used it many times. This particular yeast is a second generation that I washed. So that part makes me a little nervous - I've used the other half of this same harvested yeast in another batch that turned out great, but the odd smells make me wonder if I picked something up. Time will tell, I s'pose. I dry-hop this amber so I'll have a good look in a couple weeks when I rack it into a glass secondary.
The "My" is not nearly that clever. It's just my own recipe and seemed like an easy way to denote this recipe from another. It's been through a few revisions (this batch being the biggest change - going from an extract recipe to AG). Originally, I planned to try and save a few bottles from each 'version' so I could verify that my tweaks were doing what I meant but I'm not disciplined enough to hold back any bottles. :-/
