CORBY DISTILLERIES <CDL.TO> TO BUY HEUBLEIN UNIT Corby Distilleries Ltd said it has agreed to buy Toronto-based McGuinness Distillers Ltd from Heublein Inc for about 45 mln dlrs in a move which Corby expects to add significantly to domestic earnings. Heublin is a subsidiary of Grand Metropolitan PLC (GMHL.L). Corby said McGuinness will remain a seperate business unit with a seperate sales force. McGuinness markets liquers, brandy, and other liquors and has entered the fast-expanding wine cooler market, Corby said. Corby said it expects to benefit from McGuinness's succesfull introduction of schnapps and coolers and its strength in traditional market sectors. Heublein said the sale does not include McGuinness's Calona Wines Ltd, a Canadian wine company. Heublein said it is will still be represented in Canada by Gilbey Canada Inc. reuter
