Today is the last day to get Scotch whisky into the US before tariffs kick in

It’s a slow, steady process that may take weeks—appropriate for a product which may have spent as much as a quarter-century sitting peacefully in barrels. While the tariffs cover a long shopping list of British and European products, the largest product group affected will be single malt whisky: in the year ending Aug. 31, it alone made up 12.4% of all exports to the US from the UK, to a total cost of $1.75 billion, according to trade specialist Panjiva. Drinks giant Diageo, of Lagavulin and Talisker fame, is the largest affected company, making up 31.2% of shipments to the US in the twelve months ending September, followed by Pernod Ricard and Bacardi.
