In time samples came our way, and.... well, we can say that we finished the 2009 Cuyo Chardonnay ($20/3L). We found nothing remarkable about the wine, but it did not take up much space in the fridge, and it was often handy to have a drinkable white at the ready with no deliberation about what bottle to open, let alone chill. So high marks for convenience, at least.
We were disappointed by the 2008 Cuyo Malbec ($20/3L). Malbec is Argentina's signature grape, so we expected much more from this wine, and the box remains nearly untouched.
Our hopes remain for the 3L bag-in-box category. As soon as someone actually does package a high-quality wine this way, the market will be theirs. But so far the promises to do so have gone unfulfilled.
