(Telegraph) - Office for Budget Repsonsibility (OBR) forecasts suggests that wine drinkers will pay an extra £1.6bn in duty over the next five years. The OBR said that total wine duty revenue of £3.3bn forecast for the current tax year would rise to £4.9bn in 2016/17. The Chancellor, George Osborne, confirmed in his last Budget that he was going to stick with the duty 'escalator' introduced by the last Labour government, under which alcohol duties will increase by 2pc above inflation until 2015.
