Average value WINE EXPORTS UNPRECEDENTEDLY TOUGH MARKET REFLECTED IN 2021 EXPORT FIGURES Australian wine exports fell 30 per cent in value to $2.03 billion and 17% in volume to 619 million litres in the year ended December 2021, according to the latest export figures released by Wine Australia. Wine Australia’s general manager corporate affairs and regulation Rachel Triggs said the export figures were reflective of the unprecedentedly tough market conditions over the past 12 months resulting from tariffs imposed on bottled Australian wine imported to mainland China, the continuing impact of the global freight crisis, and a counter-swing in some markets after COVID-19 related

alcohol volume growth of 0.7% CAGR during the same period. Beer and cider were the largest NOLO alcohol category (at 75% volume share), with no-alcohol beer projected to drive growth at more than 11% CAGR over the study’s 20212025 forecast period. No-alcohol RTDs and no-alcohol spirits were both expected to post about 14% CAGR volume growth. As the taste of low-alcohol wine is perceived by many consumers to be superior to that of no-alcohol wine, low-alcohol wine is expected to grow almost 20% CAGR between 2021 and 2025, with no-alcohol wine projected to rise by a more modest 9% CAGR.

“New Zealand wine sales for 2021 were 324 million litres, meaning they were 48 million litres more than was actually produced in the 2021 vintage. This stock drawdown highlights that we desperately need a bigger harvest in 2022 to replenish cellars and help satisfy international demand. “Over the past 12 months many New
