The Tea Blending experience is available online here:
https://www.fortnumandmason.com/tea-blending-landing
You will be asked to complete a series of questions online that will help to produce a blend of tea specifically tailored to your preferences. You can also add a personalised label to the caddy to add that extra special touch.
There is a 16 character limit for the personalisation and this will always appear in upper case characters on the front of the tin.
The Tea Blending experience is also available in the Piccadilly store.
