The binned beer was worth £331 million in sales, based on £3.81 per pint on average, the British Beer & Pub Association (BBPA) said.
The BBPA said it carried out a survey of its members – which brew 90 per cent of the UK’s beer – to estimate how much had been wasted since the start of the pandemic.
Emma McClarkin, the association’s chief executive, called for an extension to the VAT cut for the hospitality sector and a reduction to the UK’s “excessive” beer duty – the tax on selling and producing beer – to help save the industry.
She warned that there would be a “wave of closures” and job losses in the sector unless the Government provides further financial support.
Ms McClarkin said: “Our sector is in limbo. And at several points in the last 12 months, pubs and breweries have effectively had to pour their revenues down the drain.
“We have no idea or clarity from Government on when we can reopen again.”
If pubs are told to stay closed beyond March, Ms McClarkin said further Government grants would be needed to support them.
“Without this, neither pubs or brewers will be around to brew and serve beer when we can reopen”, she said.
