A trio of picks from RICHARD EHRLICH. First up is 2003 Stella Bella Semillon/Sauvignon Blanc (40.79 for six bottles, down from 51.24; Sainsbury's), a 'great wine with Riesling-like lime intensity. A steal.' Next is 2004 Terre da Vino Roero Arneis (5.99, or 5.09 each when two are bought; Majestic), 'a fresh, citrussy and nutty white from a distinguished producer of Barolo'. His final choice is for 2004 Dourthe No.1 Sauvignon Blanc (4.99; Waitrose).
