First off, this is the first canned wild / sour beer from the BarrelWorks brand of Firestone Walker and second this could be an emerging style trend. The sour flagship that tries to win back ground from the overly fruited dessert beers while staying traditional.
You can read more about the three aged beers that were blended into this one beer right HERE.
When I first saw the above image, my immediate thought was that The Rare Barrel was doing hard seltzers. After a breath, I saw that, in fact, a canned golden sour and that is exciting. First because it will be a lower price point (hopefully) and second because the 16oz size is better to appreciate the acidity for us with sensitive stomachs. Lastly, it will shatte the myth that spurs have to be presented in bottles, as lovely as those presentations are.
