Consumer website Which? enlisted 79 tea fans to blind taste and rate 12 everyday teas from supermarkets including Asda, Sainsbury’s and Tesco.
The testers compared the supermarket own-brand products with popular brands such as PG Tips, Tetley, Twinings and Yorkshire Tea.
Each tea was sampled by 79 taste testers, served black and brewed according to the instructions on the pack. Testers were then permitted to add their usual amount of milk and sugar.
They rated the taste, mouthfeel, aroma and appearance of each tea and shared what they liked and disliked about each one. One supermarket tea emerged victorious in the taste test, costing less than half per cup compared to the branded options.
Asda was the top choice, with Which?, reports the Liverpool Echo.
Tasters awarded it high marks for aroma and appearance. Over two-thirds of the testers agreed that the colour and flavour were just right.
The Asda teabags are priced at £3.20 for 240 teabags online, just over 1p per beg, while 80 tea bags cost £1.20 and you can also purchase their own-version ASDA extra strong 80 tea bags for £2.00.
After sampling PG Tips Original, more than two-thirds felt it had a good heart colour and many were pleased with the strength of the bitterness.
Almost two-thirds believed the strength of the flavour was also spot on. The product came second with a score of 71%.
Tetley tea bags tied for second place after being well-received by the tasting panel. Tasters thought the tea looked good and had a pleasant mouthfeel and enticing aroma.
A majority of 59% found the Tetley tea to have a bitter taste, while 27% felt it was excessively so.
Tetley tea bags can be bought from various stores at £3 for a pack of 80, and PG Tips are available at the same price for 80 bags.
The remaining teas in the test saw a tight competition, with Aldi, Co-op, Waitrose and Yorkshire Tea all scoring 70%.
Tesco teabags, along with Twinings, were at the bottom of the list.
Despite achieving a score of 67% for its good bitterness levels, some tasters thought it was too dark in colour and lacked strength.
They are priced at £1.25 for 80 bags (50p per 100g, 2p per tea bag).
The flavour of Twinings was less favoured compared to its competitors, with less than half of the tasters giving their approval.
