    • ‘Highest in congeners are drink spirits such as whiskey, scotch, bourbon, port and brandy.’

    • ‘Vodka has very few congeners and bourbon has quite a bit.’
    • ‘As a rule, the more expensive your alcohol is, the greater the chance that it's been through a comprehensive distillation process to filter out many of its congeners.’
    • ‘The darker the drink, the more congeners and other hangover-causing substances you'll imbibe, so tread warily around ports and heavy red wines.’
