Quite a way to go before these are on a par with the reds (see here and here for a couple of recent videos on Argentine reds)

Septima Sauvignon Blanc 2009, Mendoza (£6.99 Codorníu UK)
Not a taut, buttock clencher, almost nutty Bordeaux style, quite rounded, light citrus, hint of pear, simple but honest style. C+ (don’t bother visiting the Septima web site – at the time of writing (19/1/10), the most recent thing in the ‘Latest News’ section is from January 2006)

Tapiz Single Vineyard Sauvignon Blanc 2008, Valle de Uco, Mendoza (£11.49 Hispa Merchants)
Richer, peachier style, Sauvignon for Chardonnay fans, rhubarb and apple crumble edge, powerful but never OTT, not like Kiwi or Loire Sauvignons, keep it for fuller food. B(+)

Chakana Torrontés 2008, Mendoza (£8.49 J E Fells)
Slightly bitter and oily, a false citrus character like washing-up liquid or lime/lemon jelly cubes, lacks freshness and fading fast. 0

Finca La Anita Semillon 2008, Mendoza (£17.49 Hispa Merchants)
Is this as fresh as it should be? There are nice bruised/baked apple and musky pear flavours, along with a touch of rhubarb and a slightly buttery note, but the hint of raisin and the dry fruitcake edges make me wonder whether there’s a problem with oxidation here. Hmmm… ??
