On National Tea Day, many Brits will celebrate the humble cuppa with its natural accompaniment - a biscuit.

But what type will we select? For many people, the crucial factor in choosing is – how well does it dunk?

Fortunately, scientists working for Wren Kitchens have conducted an experiment that puts the UK's favourite biscuits to the test, to discover how long each of them can last before crumbling under the pressure.

The boffins, acting under laboratory conditions, found that - spoiler alert! - the No.1 biscuit for dunking was... the mighty Bourbon!

The Method

Each biscuit was dunked half way into a freshly brewed cup of tea (temperature is a key factor!) and held in place until it broke. A stop watch was used to record the breakage time.

The Results

Once the experiment was over, it was crunch time for our beloved baked goods. Each biscuit was ranked by its breaking point, from lowest to highest – and also included a RDT (Recommended Dunking Time):

Additional Tests

Upon completion of the above testing, the tea testers then decided to test a few extra biscuit varieties – just to see how they fared against the ‘Classics’. The Chocolate Digestive Thin was quite the dark horse – lasting a surprising 1 minute 5 seconds!
