FROM Barefoot to Brancott, Which? had revealed the supermarket selling branded wine for the cheapest prices - and the most expensive.
Tracking prices from February to April 2024, it compared 15 big name wines across Asda, Morrisons, Ocado, Sainsbury's, Tesco, and Waitrose.
For Clubcard holders, Tesco was the cheapest on average for 13 out of the 15 bottles the consumer champion compared.
It was also the cheapest supermarket based on the total price of all 15 bottles, which cost an average £108.43 with the loyalty scheme.
However, non-members would have paid more at Tesco than any other store for eight of the 15 branded wines in Which?'s analysis
In total, non-members would have paid 11% more on average than Clubcard holders at Tesco, equating to £120.67.

Morrisons, Sainsbury’s, and Waitrose also offer member-only discounts, but less frequently on wine.
Aldi and Lidl were excluded as both supermarkets don't sell the brands analysed.
Asda followed closely behind Tesco's Clubcard pricing, at just £2.57 more on average.
It offered the lowest prices on Yellow Tail Pinot Grigio and Brancott Estate Sauvignon Blanc and was second-cheapest on average for eight of the 15 bottles.

However, none of Asda's prices are exclusive to loyalty scheme members.
Which? also tracked how many times the same 15 branded bottles were discounted over a 12-month period.
How can I cut costs at the supermarket?
THERE are plenty of ways to save on your grocery shop.
You can look out for yellow or red stickers on products, which show when they've been reduced.
If the food is fresh, you'll have to eat it quickly or freeze it for another time.
Making a list should also save you money, as you'll be less likely to make any rash purchases when you get to the supermarket.
Going own brand can be one easy way to save hundreds of pounds a year on your food bills too.
This means ditching "finest" or "luxury" products and instead going for "own" or value" type of lines.
Plenty of supermarkets run wonky veg and fruit schemes where you can get cheap prices if they're misshapen or imperfect.
For example, Lidl runs its Waste Not scheme, offering boxes of 5kg of fruit and vegetables for just £1.50.
If you're on a low income and a parent, you may be able to get up to £442 a year in Healthy Start vouchers to use at the supermarket too.
Plus, many councils offer supermarket vouchers as part of the Household Support Fund.
It found three bottles were discounted more than 50% of the year for Tesco Clubcard members, and one was reduced for over half the year at Asda.
The Chartered Trading Standard Institute has said discounts lasting for "a materially longer period than the higher price was offered" are "less likely" to be compliant with its guidance.
When Which? put this to Tesco, it disagreed and said it complied with all the rules governing promotions. Asda did not provide a comment.
Four-fifths of the analysed bottles were on promotion at Asda, Sainsbury's, and Tesco for at least 40% of the year.
Notably, Waitrose charged 24% more for Barefoot White Zinfandel Rosé compared to Tesco’s Clubcard price.
Ele Clark, Which? retail editor, said, "Shoppers should compare prices, especially for specific brands.
"Tesco offers great deals with a Clubcard, but without it, you could pay up to 16% more."
While Tesco's Clubcard can save you money on wine, if you don't have one, you might want to shop elsewhere.
NHS guidelines on drinking alcohol
According to the NHS, regularly drinking more than 14 units of alcohol a week risks damaging your health.
To keep health risks from alcohol to a low level if you drink most weeks:
- men and women are advised not to drink more than 14 units a week on a regular basis
- spread your drinking over 3 or more days if you regularly drink as much as 14 units a week
- if you want to cut down, try to have several drink-free days each week
If you're pregnant or think you could become pregnant, the safest approach is not to drink alcohol at all to keep risks to your baby to a minimum.
