(2015) This Chardonnay comes from the 500-600m altitude vineyards pf Chivite in Navarra and is fermented partly in stainless steel and partly in French oak barrels (2nd and 3rd use). It is made by Bordeaux white wine superstar Denis Dubourdieu. A lovely cool nose of schist, river stones, flint and complex sulphides, with a fabulously punchy palate, loads of fruit, loads of tangy Seville orange and lime acidity, long and really rather superb in a Chablis mould. Unfortunately it is in only six branches of Waitrose, but it is available from their online store too.
