Don't be afraid of this hop. It is really quite nice, and as I found out, quite forgiving. Its a bit of a story....
I was planning to back to back beers, both 25 litres. One 10 minute Summit Pisener, and a Bluetongue Lager. I had planned to use one 50g addition of Summit at 10 minutes. The wort came to the boil, and without thinking, I threw in the hops. While they were still in the air heading for the boiler, I realised my mistake. At 17% apha, his is going to be one bitter beer. What to do? I ended up reducing the boil to 40 minutes. I then did the second (Bluetongue grain bill) and did not add any bittering hops, just 20g at 10 mins, and 30g at flame out. I then blended the two beers into two fermenters.
Anyhoo, to cut a long story sort, I had two and a half kegs of Mistake Summit Lager. I am just finishing the first keg, and it is a very nice beer. Again, absolutely no onion or garlic, just a floral, stone fruit type flavour this hop throws. Disaster averted. One and a half kegs to go.
I will definitely have Summit as one of my regular beer hops, but I migt have to give them a bit of a break before I do my next one.
