Madrid is currently scorchio and of an evening you will find the locals repairing to high places in the hope of catching a Himalaya style breeze. And since man does not live by altitude and atmosphere alone if you can find a terrace with the good stuff then all the better.

One such spot is El Mirador del Thyssen – the roof terrace of the Thyssen museum – currently featuring none other than David Trillo as chief of the roof and wineslinger, who is by all accounts revelling in the bottles he has found tucked away in the cellar.

And this is the good stuff, too. Not my first bottle, but hadn’t had it for a good while – January 2017 it says here. 100% Xarel Lo, dosage of palo cortado and amontillado, 30 months on the rack and must be over five years on the bottle.

And what was back then a big exuberant cava is now sharp and fine – still yeasty, floral, apple and nut on the nose, but then sharp, fizzy and crisp on the palate, really cracking nutty, mature apple flavours and that fresh saline finish.

Top class, refined summer bubbles.
