I've not used Nelson Sauvin hops before, so ordered six ounces to try. These were grown in New Zealand using organic farming techniques. According to the internet, Nelson Sauvin hops are:
12% Ave. AAU. This new and unique variety was bred in New Zealand and released in 2000. Named for its aroma which is remarkably similar to the fresh crushed gooseberry aroma of a Sauvignon Blanc grape. Nelson Sauvin has the unique ability to impart a distinctive cool climate white wine fruitiness. Offers both a refreshing green grapes flavor, hints of pineapple, with a touch of earthiness to balance the flavor profile. This dual-purpose variety can be used to produce big punchy Ales as well as subtle yet bitter Lagers. The fruitiness may be a little overpowering for the un-initiated, however those with a penchant for bold hop character will find several applications for this true brewer's hop. A must try incredibly unique hop, and there is really no recommended substitute although it shares characteristics with Cascade, Centennial, or Chinook.
I brewed an APA featuring these hops. I first wort hopped with some Chinook, but the remainder of the hops have been the Nelson Sauvin, at 10, 5 and 1 minutes. After fermenting for ten days or so, most of the time at 60F and towards the end of that time at 64F, today I racked to a new carboy and added more Nelson Sauvin to dry hop. I'll probably bottle on Thursday night.

When I tasted the hydrometer sample, it did have a very pleasant and unusual aroma, not citrusy, but fruity. I'll try to remember to report back when the beer is ready to drink.
