I can understand the system whereby duty is applied by strength of alcohol content, but the illustrative poster is misleading. No White wines above 11%, just one dubious SB at that level and no quality English ciders at 6-8% which will be hit hard by the increase.
So, someone drinking 8 pints on a big night out saves next to nothing (and still consumes 16+ units) while a couple enjoying a bottle of good red or white wine pays almost 50p more for their shared 10 or 11 units. Is this part of ‘levelling up’?
