Some info.

I'm not 100% sure, but it appears it is still available in the UK, also thru the post.
Britishfood.com is an American option. britishimports.com for Canada.

The distributor/maker Unilever plc. seems to have changed it to an odd shape of teabag though. So buy it loose, or take it out of the teabag to brew.

PG Tips is the next grade down(also distributed by Unilever). Or try Brooke Bond 'D'.

Personally I like Yorkshire Tea, but my body doesn't accept Black Tea anymore.

Until I found this forum, I never knew about Green or Vanilla Rooibos-hope to try soon.

UK also sells a Green Earl Grey. Tweet
