Roc St Vincent Bordeaux Sauvignon 2013, France (£8.25 Sainsbury’s)
Fresh sappy style, nettles and cut grass to the fore, Grannie Smiths apples and grapefruit close behind, and a touch of Alka Seltzer-like minerality to add further zest. B(+)

Château Gaillard Touraine Sauvignon Blanc 2013, Loire, France (~£10 Vintage Roots, Sip & Learn)
I like the rich quince, rhubarb and citrus flavours and earthy mineral notes, but lurking in the background is an every-so-slightly dank cheese rind (geosmin). Nearly but not quite. B(+)

TerraVin Sauvignon Blanc 2013, Marlborough, New Zealand (£16 Selfridges, Fortnum & Mason, Simply Wines Direct)
Gooseberry and asparagus aromas leap from the glass, but there’s also a touch of the cabbagey/tinned pea character that some Sauvignon acquires with age. Good, but wish they’d either done it cleaner with no oak or gone the whole hog with wild ferment and (old) barrel maturation. B+
