Castle Brook 2009
Most English sparkling hails from the south coast, but these grapes are grown on a former Roman vineyard in Herefordshire's lush Wye Valley by an asparagus-farming family, although the wine is made near Brighton. Simply gorgeous: light, effervescent, floral, grassy. Summer in a glass. £32, castlebrookvineyard.co.uk
Le Grand Cros La Rivale NV
A sparkler from a specialist rosé vineyard in Provence that also makes very classy still wines. This is a blend of Mourvèdre and Cinsault grown on sun-baked terraces: classic strawberry, raspberry and herb flavours, enlivening and refreshing. The perfect early evening aperitif with canapés. £9.99, nywines.co.uk
Castellari Bergaglio Ardé Gavi DOCG
A delicious sparkling Gavi from Piedmont in north-west Italy, demonstrating all the qualities of the local Cortese grape: fine acidity with crisp flavours of brioche and citrus, and a lingering finish. An ideal companion for oysters, scallops or any crustacea.
£21.50 (as part of a purchase of six mixed bottles), libiamowines.co.uk
