Italian wine Canaletto is to join the increasing number of wine brands expanding into smaller bottle formats.

Producer Casa Girelli will launch Canaletto Pinot Grigio delle Venezie and Montepulciano d'Abruzzo in 25cl bottles - the equivalent of two glasses - at an rsp of £1.99 each.

"With so much concern about the number of units we drink, we feel the consumer will appreciate the option of buying wine in this smaller size," said MD Stefano Girelli.

Doctors have called for producers to provide wine in smaller bottles in a bid to curb binge drinking. Last week Waitrose announced it was to increase its range of smaller bottles by 50%.
