Quinta do Crasto not only has some of the most breathtaking views in the beautiful Douro Valley, but it has mastered the art of making red Douro table wine a thing of beauty, while many of its neighbours continue to overcomplicate and over-oak the stuff. This is an utter delight: scented with jasmine, bulging with ripe black plums, mulberry and blueberry fruit with the merest tug of chewy tannin, and as you swallow, back comes the jasmine.
