California is the headquarters of the best hoppy beer on the planet. That also happens to be the state that Stone Brewing and Sierra Nevada call home. And now, the two breweries have finally collaborated for Stone + Sierra Nevada NXS IPA. Making NXS involved brewing two batches of IPA. The first batch was split in half, with 50% being aged in gin-infused bourbon barrels and the other half aged in rye whiskey barrels. Batch number two was a fresh IPA, which was blended together with the first batch to make a hopped up IPA unlike any you've tried before. Leave it to two of the pioneers in craft beer to join forces and create yet another IPA we can't get enough of.
