Introduction

The data in this report is supplied by leading market analysts who are continually working to improve accuracy, resulting in slightly different samples each year.

This creates an artificial level for trend analysis year-on-year across all channels. However, the sample is adjusted retrospectively and change percentages are accurate, although value and volume data should not be compared to last year’s report. Unless otherwise stated all volumes represented are "as sold" not "as drunk". For ease of use some figures have been rounded to whole numbers. This may result in small discrepancies in chart totals but does not affect the accuracy of the background data. Data is correct at time of going to print.
