One of my Belgians, brewed on Sept 4th, 2005... along with a Maudite dated Dec 17th 2005.
This was the 4th generation of the Trappist yeast, which had been stored for 8 months. It had been attenuating like crazy, so I increased the crystal... almost 2lbs in this one, and it still finished at 1.012. Even so, it was a bit too much for my taste now.
The Unibroue was surprisingly yeasty, and not at all oxidized (industry standard bottle with foil). It was easier drinking, but my homebrew had more depth.
Mixed 50/50, it was better than the sum of its parts.
