Onion-y/Garlicy Hops (for the fellow beer nerds)

I grabbed some bell's 2 hearted yesterday and threw one in the freezer. Last time i had 2 hearted (about a year ago) i remember it being a fantastic beer. However, yesterday, i did not get that impression. I found the beer was high quality, but the hop character of this beer has changed. Previously i remember getting grapefruity/citrus like character. The one i drank yesterday tasted like green onion/garlic.

Great Raft's Commotion (and to some extent Grace and Grit) both have this same intense green onion-ish flavor to these 2 beers as well.

Initially, i thought Mosaic was the culprit, as i've heard from many homebrewers have had problems with their mosaic hops tasting like green onion. However, after investigation of these 3 beers, that doesn't seem to be the case.

Bell's Two Hearted consists of all Centennial Hops.
Great Raft Commotion's hop bill is Bravo, Cascade, Citra, Mosaic
Great Raft Grace and Grit hop bill is Citra and Amarillo.

As a homebrewer i've used all of these hops before in large quantities for IPA's. Centennial has never given me that funky garlicy flavor. Grace and Grit's hop bill is similar to ones i've made and mine have been what is now described as Juicy, and throws off tons of Citrus. And Commotions Hop bill shouldn't be throwing off these flavors either. I've used Mosaic many times and the flavors have always been enjoyable. A Christmas IPA i've made usually threw off a lot of blueberry flavors, and my last IPA was a heavily late hopped Mosaic, Amarillo, Citra, and Cascade IPA and tasted bright, fruity, Citrusy, with hints of grapefruit.

So in comparison to the latest batches, the previous batches of 2 hearted were fantastic, yet the stuff i had yesterday wasn't that good. Also, with Commotion, right after they changed their recipe for the better, i got loads of grapefruit, but don't get that today.
And even Grace and Grit, the batch i had before the last one, was darker in color, but i had a much fruitier hop aroma and flavor. The last batch that was lighter in color tasted of garlic and onion.

Does anyone have any insight of what is causing this? I used to think it was just Mosaic, but that doesn't appear to be the case. Maybe it's hopping rates, or where they are sourcing the hops. Or maybe my taste buds are out of whack.
