It is the one of the better versions of the Spanish Freixenet cava. Similar that KLM used to serve on their lounges and onboard their European Select class. I have not tried their new European profuct. And better than Lufthansa offers in their senator lounges and onboard their European föights. So not so good as BA lounges but at least as good as most European carriers and even better than most of the carriers onboard. I havent seen champagne in the AF lounges either (first lounge I have not tried and I admit that they serve a drop of cgampagne in long-haul Y).
