If it's only since June???
You betcha it will taste hot...
When people think of Barleywines they thing in terms of a year for mellowing, or at least several months.....like 6-8 minimum.
My 1.090 Belgian strong took 6 months before it stopped tasting like rocket fuel....
You absolutely NEED to give it more time to mellow....

I wouldn't touch a barleywine I made til it was a year old....
