Three nice older bottles opened at the Gonzalez Byass 10th anniversary dinner last week:

Champagne Deutz Blanc de Noir 1975 France (magnum)
This Pinot Noir comes from Grand Cru Aÿ, and the wine was resting on lees for 37 years before bottling in 2012. A yellow colour, this has a taut citrus nose with subtle pear and toast notes. The complex, taut palate has some herby notes and a hint of honeycomb. Very tight, with some wax, lanolin and toast. Savoury and detailed with keen acidity. 93/100

Quinta do Noval Colheita 1937 Douro, Portugal
Powerful, concentrated and intense, this is lively and spicy with astonishing richness of flavour. Bold acidity and lively spicy notes couple with notes of treacle, raisin, old casks and dried herbs, with an eternal finish. It has some of the complex characters that you might find in an old whisky, and it is utterly delicious. 97/100

Gonzalez Byass Pedro Ximenez 1914 Jerez, Spain
This has probably been in bottle for 20 years: little is known about it. So complex and intense with vivid raisin, black cherry, christmas cake and spice flavours. Viscous and concentrated with tar, raisin and treacle, kept fresh by keen acidity from the concentration that occurs with a long time in cask. A powerful, remarkable wine. 96/100
