The wine brand, Black Tower, once the best-selling wine in the UK market, is to be re-launched in the summer by UK distributor, Grants of St James's. The German white wine, something of an icon of 1970s design and culture, will be the subject of a £1m advertising campaign with the aim of wooing young drinkers back to the brand. The re-launch is scheduled for June with the ad campaign to follow in September.
