I'm glad you asked because I just used them on my last three batches. My first batch was an IPA that I used 2 oz of pellets in a bag to dry hop the keg with. All I got was onion and garlic flavors from it. I rushed a pulled the bag out of the keg and was able to get my beer back to drinkable.
Second batch was a pale ale, but this time I used .5 oz for 60 minutes and .5 oz for 10 minutes....... not as bad, but I still got a hint of onion and garlic. It's a good beer, but without those hops it would have been a great beer.
So I tried them once more in another IPA. Using 1 oz at 60 minutes. This one didn't have onion and garlic and it did a good job at bittering.
In summary: I hope an asteroid crashes into a summit hop field and wipes them off the planet. Haha I just never got the citrus flavors that others have claimed to get from these hops....... that's why I tried it on three occasions just to be sure before I wrote these hops off.
I wasn't a fan
