Knappstein Clare Valley Riesling, 1998 (selected outlets of Dunnes Stores, £7.99). I recommended this tangy, lime-tinged Australian last week as a partner for ceviche, and can't resist mentioning it again. One of the very best at a bargain price.
Wirra Wirra Hand Picked Riesling, McLaren Vale & Clare Valley, 1998 (Oddbins, £9.99). Wonderfully perfumed with that distinctive petrolly edge, this is a complex, engaging wine whose light, subtle flavours linger just as you'd wish.
Peter Lehmann Barossa Reserve Riesling, 1994 (Vintry Rathgar, Duffys Terenure, McCabes Merrion, Sweeneys Dorset Street and Fairview, Higgins Clonskeagh, Jus de Vine Portmarnock, usually about £12.99). A new discovery at the Australian tasting - and what a treat! Classic Riesling aromas, tingling acidity, ripe fruit, a long, bracing finish . . . not much wonder it was judged best Riesling in the world at last year's International Wine and Spirit Competition. Grapes from the cool Eden Valley, not the hot Barossa.
Graacher Himmelreich Riesling, Mosel-Saar-Ruwer, Dr Weins-Prum, 1997 (Karwigs Wine Warehouse Carrigaline and many SuperValus/Centras/Roches Stores, usually about £8.50). The ultimate summer tipple - feather-light (alcohol only 8.5 per cent) and slightly spritzy, with ripe apple flavours behind.
