Let there be throughout our kingdom a single measure for wine and a single measure for ale and a single measure for corn, namely 'the London quarter'Beer Day Britain was instigated and driven forward by beer sommelier, writer and drinks educator Jane Peyton. It took place for the first time in 2015. The main focus of the day is the National Cheers To Beer that takes place at 7 pm when people also sing the Cheers To Beer anthem co-written by Jane Peyton.
