Keg at BrewDog Waterloo, 27/04/23. Clear golden blonde with a white cap that thins to a swirl. Nose is white grape, vanilla stained oak, herb, funk, tangy fruit esters. Taste comprises green berry must, lactic tang, sweet and soured caramel effect, vanilla, barnyard notes, hay bale, funk, dusty oak. Medium bodied, fine carbonation, semi drying close with a mellow acidic spike. Not a huge fan of pastry sours but this worked well and sipped easy for 8%.
