‘Dull and musty’: the best (and worst) supermarket breakfast teabags, tasted and rated

We spill the tea on the supermarket bags worth your cuppa – and which should be left to stew

• The best (and worst) supermarket coffee

My grandma would turn in her grave if she knew I tested these teabags by brewing them in a cup, but that’s how I drink tea mostly. Or at least I did until I met tea specialist Matt Writson, who helped me test today’s teas with the industry-standard cupping process and, afterwards, introduced me to some mind-blowing whole-leaf teas. We studied the appearance and aroma of the wet leaves in an observation bowl, then the colour and clarity of the tea itself, before supping it from small bowls and aerating the tea to maximise its surface area.

The bags I tested ranged from 2p to 34p a pop, but when you think about the quality and sourcing of the higher-priced teas, even they are incredible value. We scored them on flavour, structure and balance, plus certification, trading standards and sourcing. I also awarded points to plastic-free bags – it seems the industry is finally responding to the uproar against microplastics, though some producers need to catch up and work without the polypropylene glue that’s still often used to seal teabags.
