MANY pubs have brought in bigger wine measures which cost drinkers more and may put them at risk, a new guide warns.

The standard 125ml glasses used a few years ago are being replaced with 175ml measures, says the 2006 Good Pub Guide.

Customers are at risk of going over the legal alcohol limit for drink-driving because they do not realise how much alcohol the bigger measures contain, says guide editor Alisdair Aird.

Large glasses of wine frequently come in 250ml glasses, which hold a third of a standard bottle.

The Good Pub Guide is calling for all pubs selling wine to use 125ml glasses as their standard size.

* The cost of a pint of real ale is an average £2.24, a 4% increase on last year, the guide says.

Surrey is the most expensive area, at an average £2.51 per pint. Lancashire is cheapest, at £2, with Yorkshire at £2.10.
