Dogfish Head & Rodenbach Breweries Collaboration: Vibrant P'Ocean

Still working through Moran's collection of sours. Dogfish Head's Vibrant P'Ocean is a collaboration with Rodenbach Brewery. The Belgian brewery contributed a foeder-aged sour. A foeder is a wooden barrel, usually used to age wine, but has been used recently to age sour ales. Dogfish Head's portion was a kettle aged sour. Kettle aging refers to a quick-souring process rather than the slow process of aging and souring found in lambics, goses, berliner wiesses and other traditional styles. The Dogfish Head sour was brewed with pilsner malt, malted wheat and elderberries, with some elderflower and Belgian fleur-de-sel mixed in. Vibrant P'Ocean a cranberry hue, and the main taste is indeed cranberries (maybe elderberries taste like cranberries). I don't know if there's a standard for measuring tartness in ales, but I'd give it a 3 out of 10 on the IGB tartness scale. There's a little bit of lemonade in the mix, as well as cherry. Like yesterday's offering, this might be a good introduction for a neophyte into the world of sours.
