It's a Petrus sour beer pack. Although I should have paid a bit more attention as on one side of the box it says sours and thr other side says traditional. Basically the box has 3 Petrus sours and 3 of their traditional ales. I only had one of them so far and if it's any indication I'll be quite happy with all of them:) At the price the shop was selling them it's a steal anyway. Buying two single bottles from online retailers here is more expensive than buying the pack of 6.
