Wine fans looking to save cash on their favourite tipple can sniff out the best deals at Asda, a watchdog has revealed.
A study by Which? found the supermarket was the cheapest for 60% of popular plonks such as Barefoot and Gallo.
According to the research, drinkers can save up to 22% on upmarket labels by being as savvy about where they stock up as they are about their tipple.
For example Casillero Del Diablo Sauvignon Blanc had a price tag of £6.96 at Asda but was 16% dearer at £8.10 from Waitrose.
Gallo Family Vineyards Summer Rose cost £4.24 at Asda but was 14% more at Waitrose with a bill of £4.85.

And Barefoot Malbec was £6.15 at Asda but £6.89 at Waitrose which was the most expensive supermarket, the study found.
While Asda was tops for popular brands, Sainsbury’s was the best for cherry picking deals on posh labels.
For the research found award winning New Zealand wine Brancott Estate Sauvingnon Blanc was £7.41 at Sainsbury’s but a hefty £9.01 at Waitrose - a difference of 22%.
Morrisons was named the toast of the town for overall offers with 17% of its plonk slashed in price at any given time and 22% of the range at bargain prices between November and December last year.

Connoisseurs looking for deals on wine varieties such as pinot grigio and cabernet sauvignon can bag bargain wine from under £4 at discounter Lidl, Which? said.
For just £3.80, wine buffs can buy a bottle of tempranillo at the chain along with merlot for £4.38.
And shoppers can pop a bottle of syrah into their baskets for £4.01 at Aldi and pick up a cabernet sauvignon for £4.98.
Which? said: “Discounters Aldi and Lidl typically don’t offer deals on their wine range, preferring to keep prices low year round.”
The consumer watchdog analysed prices of 382 bottles at supermarkets Tesco, Asda, Morrisons, Sainsbury’s and Waitrose, discounters Aldi and Lidl and online store Ocado and looked at 10 of the most popular wine varieties.
Natalie Hitchins, head of home products and services at Which? said: “Our research found the price of some of the UK’s most popular wines brands can vary by up to 22% depending on where you shop, with Asda and Sainsbury’s the cheapest.
“If big-name brands are not important, wine enthusiasts can pick up a bargain at Aldi, Lidl or Morrisons, which were the cheapest supermarkets for own-label bottles of the most popular grape varieties, such as syrah and pinot grigio.”
