Not sure what an ISA is, but I know this was brewed with Nelson sauvin hops. The aroma shows off the hops a little, there is a tangy, green, vinous, acidic hop aroma. But once again, the diacetyl is there like most of the beers from this brewery. A thick aroma of butter, and caramel. The body, and carb are good. The finish is medium to high on the bitterness. The hops are floral, and green, and pleasant in the finish. But the malts are masked by a thick buttery flavour.
