I'm trying hard to finish the last of a 10L box of wine, but seems to be bottomless. we had a cookout last weekend and I thought it had been drained, but I had 4 glasses Wednesday and I'm on my third right now and it's still dribbling. At lunch I had a Pelforth Brune with the mason doing some stonework on the house, then when he was finished I served us each a Leffe Brune-it's customary to have a beer with your contractor when he quits for lunch and at the end of the day. That's when the 25cl bottles are very handy.
