Portugal
Portugal grows tea on São Miguel in the Azores, and what is there now is the survivor of something larger. The islands turned to tea in the nineteenth century after their orange trade collapsed, brought in Chinese specialists to teach the process and built a real industry on it. Two factories are left, Gorreana and Porto Formoso, both on the north coast of the same island. Europe's tea coast proper is the Black Sea, in Turkey, Georgia and Russia, but none of that sits in the European Union, which leaves these two as the whole of EU-grown tea.
What grows here
Black and green tea, from two neighbouring estates. Gorreana sells its blacks by leaf grade in the old British manner, from broken grades up through Pekoe and Orange Pekoe, with green teas including a Hysson alongside them and a small amount of oolong. Porto Formoso works the same way at a smaller scale. There is nothing else: tea has always been a São Miguel crop and mainland Portugal does not grow it, so the whole of Portuguese tea is two factories and a few dozen hectares of hillside.
The ground
Mid-Atlantic volcanic ground at about 38 degrees north, with the ocean holding the temperature inside a narrow band all year: no frost, no real heat, high humidity. The soils are acidic volcanic ash and the gardens run down the northern slopes toward the sea. Isolation matters as much as climate here. The islands carry very few of the pests and diseases tea attracts elsewhere, which is why Gorreana grows without pesticides, herbicides or fungicides and can state it plainly rather than as a marketing position.
Harvest seasons
April to October, then a stop. The season is long by European standards but growth is slow and the total is small. Because the climate barely varies across it, the teas are sold by leaf grade rather than by picking date, so there is no first flush premium to chase the way there is in the Himalaya or in Japan.
How it is made here
Orthodox, on Victorian machinery. The rollers and driers at Gorreana are British and date from the nineteenth and early twentieth centuries, and they are still the machines the tea is made on, which is unusual enough to be a large part of why the factory draws visitors. It also shapes the product: what comes out is a straightforward orthodox black or a simple green, made the way the equipment was built to make it.
What to look for
Two names, and both are estates rather than brands. If a packet says Azores or São Miguel without saying Gorreana or Porto Formoso, ask who made it, because there is no third producer on the island. Scale is the other check: Gorreana's entire output is a few dozen tonnes a year, so anything offering Azorean tea in quantity deserves a question. And the plants are of Chinese origin rather than Indian, so expect a mild black rather than a strong one.
How it got here
The Azores lived on oranges until blight and the loss of the export market destroyed the trade in the 1860s, and tea was one of the replacement crops tried. The first plants came in around 1860; the knowledge came in 1878, when the island's agricultural society brought two Chinese specialists from Macau to teach it. Several factories followed. What killed them was not climate but competition and emigration: the wars disrupted trade, Azoreans left in numbers and Portuguese Mozambique produced tea far more cheaply. Gorreana, founded in 1883 and in the same family since, is the oldest tea plantation in Europe still in production. Porto Formoso closed in the 1980s and reopened in 2001.
