I'm not really great at adding specific descriptors for flavors and aromas. In fact, I laugh at all the beer releases that have your typical "stone fruit, lychee, passion-ass, etc etc" combo of flavors and stuff.
But you do get a whole heap load of white whine that in fact, for those who may not care for Nelson, it may be too overpowering. This was (mostly) a single hop beer, after all. Lots of Nelson beers I've had, including this one, bring a very [and I mean VERY] subtle flavor I wouldn't describe as good...but not bad either. Your diesel seems to hint at it a little, but I don't want to say that's what I'm getting because I don't want to turn anyone off to the hop. That flavor was much more prominent as the beer was more green. It has since faded to basically nothing now. Right now it's a whole load of fruits and berry and white wine in the best possible way.
That said, Nelson by itself can be a little much if it's not your cup of tea. However it's one of my favorite hops and I'm glad I spent ~$150 on the 2020 crop and plan on ordering a few more in a few months.
