Leafwright

Leafwright buys whole leaf, not dust, and blends by hand in small lots. The Earl Grey is scented with real bergamot oil rather than flavouring, and the herbal blends are single-farm chamomile and peppermint instead of a warehouse mix.

Tins are opaque and airtight because tea fades in daylight faster than most people expect. Whole leaf also releases in stages rather than dumping everything in ninety seconds, which is why it forgives a forgotten pot.
