I've heard Sorachi Ace hops also have this onion/garlic thing when young, but fortunately this always fades to leave a unique tea-like flavor that is extremely pleasant!

I've never noticed it in Sorachi (yet).  Good hop though - I love the lemony aspect in saison. Good stuff.

Didn't someone post recently that the onion/garlic thing may come from hops harvested too late in the season? I've definitely gotten onion/garlic in summit. I find beers made with summit very unpleasant.

I heard that at a talk or a podcast too. Hops like Summit are sold on high AA, so they are left longer on the bine to maximize AA, and the sulfur compound that causes the onion/garlic goes up also.

No Summit.  Amarillo, Citra and Mosaic.  I have heard that Mosaic can lend a little onion to the soup.  I'm headed out to purge the headspace!
You sure those little purple hops weren't shallots?

Makes sense, but I wonder if Summit isn't naturally higher in the sulfur compound, too. That stuff seems to dissipate fairly quickly when I get it from other hops, but not from Summit.

I've used Summit once without any onion in a hop stand and the beer was delicious.  I've heard that copper will eliminate the sulfur compounds that gives the onion character.

I've heard of copper reacting with SO2 gas to create copper sulfate, but I haven't seen the same data showing that it reacts with thiols to remove onion flavors.

I have gotten onion from Mosaic before. FWIW, I believe it was from 2013 whole cone hops from freshops. I only ever picked it up in a single hop beer - I've never picked out onion in any other beers I've brewed with that batch.

I have been having funny issues with my stove top batches. No copper involved. Might throw a chunk of tubing in the kettle next batch.

I use my copper IC pre and post hop stand, and I generally don't have the issues. And like I posted, the occasional onion note dissipates quickly, except for Summit.

Have not built my mini chiller yet. I've bath for the small batches.

Didn't think of the small batch thing. A mini chiller is a great idea. I do small batches now and then to try hops. Can't say I'm getting onion more often with those though, and I just ice bath them too.

What I learned at Hop and Brew School is that onion/garlic is often related to time of harvest, not necessarily a single variety.

Didn't someone post recently that the onion/garlic thing may come from hops harvested too late in the season? I've definitely gotten onion/garlic in summit. I find beers made with summit very unpleasant.

I believe that was me.

Nice contribution, Jim.

I didn't notice onion/garlic in last year's crop of Amarillo, but something was funky about it. Every beer I've brewed with 2013 Amarillo has tasted kinda funny to me.

I won't use Mosaic again because of this.

So, either way, it kind of sucks.   8)

Mosaic and Simcoe... my two least favorite hops.  Personal preference.
