Most wine will see an increase of £0.44 per 75cl bottle, or a 20% increase in the duty paid (£2.67 vs the current £2.23). This increase will apply to wines with an ABV between 11.5% and 14.5%.
Wines with an ABV above 15% will see a duty increase of £0.97 (+44%) per 75cl bottle, and this increase gets bigger the higher the alcohol percentage – duty on fortified wines of +20% ABV will go up by £1.30 to £4.28 per 75cl bottle.
On the other hand, wine under 11.5% ABV will be treated more favourably. Duty on wine at 10% ABV, for example, will be £0.09 less than the current rate (at £2.14 per 75cl bottle).
