Asia's wine interest 'exploding'

The Wine Advocate, is best known as the newsletter of influential wine critic Robert Parker.

But it received a shake up late last year when he said he was taking a step back.

Since then, the business has expanded its operations in Asia and Singapore-based wine critic, Lisa Perrotti-Brown, has become the new chief editor.

She spoke recently with Sharanjit Leyl about the ups and downs of the fine wine trade, and the growing importance of the Asian market for wine producers.
