This is the largest item I have yet received for promotional purposes:
It’s a five liter “DraughtKeg” which can operate as a standalone mini-keg, or be used in the “BeerTender” keg system (proprietary to Newcastle and Heineken, I believe). And yes, it’s full of beer.
I’ve reviewed Newcastle Brown before, so that’s not breaking any new ground. But I am curious as to how well this works, and will report back accordingly.
