(2017) Austria's Grüner Veltliner is gaining some traction in southern hemisphere vineyards - I reported recently on a small enclave in Australia's Adelaide Hills - but Marlborough has also taken to the variety. Only the third vintage for Riverby, this has succulent pear on the nose, limey citrus and a hint of mineral salts. There's a delicious weight to the fruit on the palate, texture and silkiness, the sheerness of the citrus acidity sweeps through, cutting rather more tropical fruit flavours to finish dry. A really very good expression of Gru-V. Note: price and stockist quoted at time of review is for the 2014 vintage.
