2016 La Gioiosa, Prosecco Superiore Millesimato, Valdobbiadene, Veneto, Italy

(£13.49, reduced to £8.99 until December 31, Waitrose) MADE from 100 per cent glera, the prosecco grape, and supersmooth in its delivery of flavour, this is a vintage sparkler. It is beautifully refreshing and titillates the palate. I am delighted that it is discounted to such a keen price, too, so load up for Boxing Day celebrations.
