This is fino La Janda by Bodegas Alvaro Domecq. I tried their very pleasant manzanilla La Jaca a while ago and the equally decent 1730 Amontillado too – seem to be a pretty solid little producer.
Not much detail on the ficha although they do make a point of mentioning that they harvest in September (one of the issues that comes up in learned debates is the issue of the Jerez harvest taking place in August in search of less mature, less concentrated fruit).
I like it. Nice gold colour (this was served in a chilled glass, would you believe, but you still get the drift) and quite a fragrant, almond and mineral nose. Then on the palate it is fresh and saline but with a bit of bite and a nice bitter almond flavour. Quite a character and not bad at all.
