The 2013 Cos d'Estournel Blanc has quite a pungent bouquet, the Sémillon more expressive at the moment, with lime, fresh grapefruit, honeysuckle and just a hint of paw paw. The palate is well balanced with racy acidity, here the Sauvignon Blanc comes back with gooseberry and nettle notes, although I feel this needs more time to absorb the oak on the finish that feels a little disjointed at the moment. Give this another 2-3 years in bottle before broaching.
