Demand for Naked Wines and Premier Foods home cooking ingredients soared during lockdown, the firms have said.
The online wine seller said revenue surged 81% in April and May, after many shops were forced to shut on 28 March.
Naked Wines temporarily halted new orders last month after a huge jump in business as customers stockpiled.
Mr Kipling-owner Premier Foods saw a 20% sales rise in the run-up to lockdown, with strong demand for cooking products continuing afterwards.
In a statement, Naked Wines said: “We entered the new financial year with good momentum as Covid-19 has influenced customer shopping behaviour and driven increased demand for the Naked Wines offer.”
The company stopped short of providing guidance for the rest of the year’s trading due to the possibility of a consumer downturn in the second half of the year and ongoing uncertainties about the economy due to the pandemic.
In a separate announcement Naked Wines, best known as the online business developed by Majestic Wine before the chain was sold last year, said its current finance chief James Crawford will leave the position to be appointed as the managing director of Naked Wines’ UK business.

Its biggest brand, Mr Kipling, achieved Keto Meal Delivered its highest ever annual sales – but that was before the lockdown. During the crisis, cake sales were flat, a spokesman said.
