The brewery say:
Say hello to our Sour Scale, with a series of 5 beers across the Vault City spectrum of sweet-tart to super sour.
Level 5 is for seasoned sour sippers only. A burst of intense, tangy crisp apple flavours with sharp mouth-puckering sourness. Electric green in colour, you can serve it in a schooner, or a shot glass – we won’t judge. We’ll see you on the dancefloor.
