The independent family-owned distillers William Grant & Sons has acquired the Icelandic vodka brand Pölstar Vodka from The Reformed Spirits Company Ltd for an undisclosed price. The move by William Grant is part of an ongoing diversification of its traditional Scotch portfolio. In october it acquired three rum brands, Old Vatted Demerara, Wood's 100 Old Navy and Vat 19, from Diageo and Pernod Ricard, who acquired the brands when they jointly acquired the Seagram drink business.
