Now's the perfect time to get John Varvatos John Varvatos. It's the original one, and I think it's his best. Age group for this I would say is 18 and up. It's a great winter fragrance that I wore and really loved a lot when I first got into fragrances. Leather, Fig, and a bunch of other unusual notes. It really needs to be smelled to be understood. It's an awesome night out or date fragrance too.
John Varvatos vintage is solid, but I'd say it's for a bit of an older crowd (smells like 45 and up to me).
You may want to check out The Rock if you're into Rose notes, or coffee.
The Artisan fragrances are good for the summer. Black is better than the regular (which is fairly weak).
His only really bad fragrance is Varvatos Star USA--and it's mostly bad because it just has no character or personality at all to it. Smells like anything else. It was a disappointment from Varvatos.
Go for the original
