Sapporo Beer Co. said Thursday it will sell its Japan-made wines at shops in Singapore from September on a trial basis to analyze demand there as the company eyes entry into the Southeast Asian market.

Sapporo Beer, a group firm of Sapporo Holdings Ltd., will sell a total of 960 bottles of Grande Polaire, medium-priced wines made from grapes grown in Japan, at three stores in Singapore.

Sapporo Holdings started selling the wines at its Japanese restaurant in Singapore in July and plans to sell them at four other Japanese restaurants in the country, it said.

But given limited supplies of domestically grown grapes, Sapporo will prioritize domestic sales, which are growing, a company official said, adding that for full-fledged overseas sales expansion, Sapporo will first need to increase grape production.
