I bought some hop oils from hopmybeer.com a couple weeks ago. They are real aromatic hop oils that bring about strong fresh/green hop aroma, in my opinion much better and stronger than SN Hop Hunter.
It is really the raw green hop smell. I personally love it in pale ales and IPAs, as well as in Belgian ales and wheats, but I can really see how it can over power lighter beers and may not blend well with malt-dominant beers.
I love the fact that they offer so many varieties of hop oils. I think they may be the first/only one doing it right now. For $5 a bottle (that lasts a long time!) I'd definitely recommend trying a few of them!
