Stonehaven Sauvignon Blanc 2012, Western Cape, South Africa (£7.99 The Co-op)
One of those wines that grows on you. Young and sappy with decent pithy fruit, but it’s the stony mineral character that makes the strongest impression. B

Fox Gordon Family Sauvignon Blanc 2011, Adelaide Hills, Australia (£11.99 Waitrose)
Smells OK, with lemon and gooseberry (fresh and pie) in evidence. Tastes OK too, but it’s just a little too jelly-like for real class. B-

Seven Springs Sauvignon Blanc 2011, Overberg, South Africa (£11-£12 Loki Wine, Bijou Bottles, Proteas Wines, Underwood Wines, C. A. Rookes, S.H. Jones, Frasers Budgens (Yarnton & Marlborough), City Beverage Company)
Light, fresh style, with taut citrus and green apple plus something a bit more voluptuous like nectarine, and peppery mint and herb notes adding personality. Maybe not as rich as 2010, but perhaps more elegant? S(-)

Errázuriz Single Vineyard Sauvignon Blanc 2011, Casablanca, Chile (£10.99 Majestic)
Once you get past the nutty sulphur character, this is quite a full, rich style, with vanilla-scented custard apple, very ripe pear and strawberry flesh tempered by herby citrus restraint. I don’t mind the richness but I’d like a little more subtlety & poise. B(+)

Errázuriz Aconcagua Costa Single Vineyard Sauvignon Blanc 2011, Chile (£12.49 Waitrose, Wine Rack, Booths, Berry Bros, Averys, Slurp.co.uk)
A sleeker style, still quite rich (and with the nutty sulphur to start with) showing some peachy flesh, but then the herby lime and lemon flavours bring some decorum, and the overall result is very pleasing. S-

Doña Dominga Single Vineyard ‘La Laguna’ Sauvignon Blanc/Viognier 2011, Colchagua, Chile (£7.11 Waitrose)
Bit of a stand-off between the bright herby bright edge of Sauvignon and the plump peach and apricot of Viognier. Ultimately not sure whether it wants to be and finishes in flat, jelly-like fashion. C(-)
