Just had a look on the ww site and there doesnt seem to be any listings for points dependant on alcohol content so I would guess they are the same, I always drink red and a bottle is 18points if that helps at all
thanks there is someone in the office who does WW and she said that its only 4points a bottle and that Lambrusco Light is the same but just wanted to double check!
Cant find anything official but found a thread on the ww site forum that confirms low alcohol wine is approx 4 points a bottle so sounds like your mate is right-enjoy !!
