Yorkshire Tea as a brand was launched in 1977, originally conceived as a "Yorkshire blend for Yorkshire people".
[10] In the early days different blends were created and sold for different regions of Yorkshire where the hardness / softness of the water varied. Over time, and as the scale of the brand grew to be fully national, the product has evolved to one single blend in the standard orange-coloured pack. However, it retains a
hard water variant in green-coloured packs to cater for those who live in hard water areas of the UK.
