International Wine & Spirit Research

The IWSR is the world’s most trusted wine and spirits information source.

The IWSR’s methodology is unique. They are the only research company to visit the key operators every year (distributors, importers, producers, retailers, duty-free and grey operators) in each country. This allows us to gain a far better understanding of the dynamics of a country and its real, rather than reported, consumption patterns. They have a team of 15 specialist researchers who interview over 1,500 companies through face-to-face interviews in each of the key 118 local markets. This first-hand knowledge of the local markets allows the IWSR’s analysts to produce the most accurate reports and forecasts for each country rather than straight-line forecasts or analysis purely derived from desk research. Their forecast accuracy since 2009 has been within 1% on wine and 2.5% on major spirits.
