Marks and Spencer will convert its range of mini wines from glass to plastic bottles. The supermarket is introducing the measure on all its 25cl bottles which will now be made out of an environmentally friendly plastic. The small bottles of wine are popular as an in-flight drink and also sell more in the summer when they are used for picnics. Marks and Spencer currently sell around 100,000 mini bottles a week and will be the first UK retailer to convert it’s entire range of small bottles to plastic. The new bottles have the advantage of being 88% lighter than the glass alternative meaning they will reduce distribution emissions. They are also 100% recyclable and have the advantage of having a longer shelf life.
