Postal delays have prompted us to extend the deadline for replies to the latest Readers' Wine Competition to next Friday, May 19th. Write to Mary Dowey, Features Dept, The Irish Times, 13-16 D'Olier Street, Dublin 2, or to winesearch@irish-times.ie with details of your favourite recently purchased wine at £8.50 or less - name, producer, vintage, where you bought it, the price, why you liked it and if possible, in what circumstances it slipped down so well.
