Look at this. Tea! Extending right out to the horizon over there.

I 'd reached Kericho, home to Kenya 's biggest tea plantations.

Rich volcanic soil, plenty of sunshine, and rain almost every day. Conditions here are perfect.

The tea grown here is considered to be Kenya 's finest.

Which is why, after independence, several British tea companies stayed on.

The largest, Brooke Bond, is now part of the giant Anglo - Dutch firm, Unilever.

The way things are run here still bears a resemblance to how it was in colonial times.

Many of the workers and their families live on the estate where the tea is grown and processed.

Covering 50 square miles, Unilever 's enormous Kericho Estate is home to more than 50, 000 people.

They grow tea for the world here, including PG Tips for us.
