Hi, A brother-in-law has a Krupps BeerTender countertop mini-keg dispenser that serves beer at a great temperature. A few questions: - Does it use other brand mini-kegs beside Heineken? - Are the mini-kegs refillable by home brewers? - If so, how do we sterilize them between batches? It seems like an ideal concept for home-brew. Rather than bottling, just keep the mini-kegs in the fridge - and replace into the BeerTender as needed. Its portability would easily beat a standard mini-fridge set up as a kegerator.
