Sonogi
Sonogi is what Nagasaki means in tea. It is a small district at the neck of the Nishisonogi peninsula, on hills that fall away to Omura bay, and it makes steamed tamaryokucha, the curled green tea that skips the roll into needles. Tamaryokucha is a Kyushu category rather than a Nagasaki one, made in Kumamoto, Saga and Miyazaki as well, but Sonogi is where Nagasaki concentrates it, and it has spent recent years winning the national competition section for it.
What grows here
Steamed tamaryokucha, mushi-sei, close to the exclusion of everything else, sold as Sonogicha and centred on the town of Higashisonogi. Sonogi has repeatedly taken the top producing-region award in the tamaryokucha section of the national tea competition in recent years, which is a small category and a real result inside it. Sencha is made here as well, but the curled leaf is what the name buys.
The ground
Small steep plots on hills dropping to Omura bay, so the gardens get sea air and a wind off the water that most Japanese tea districts, sitting inland in river valleys, never see. Growers here credit the sea breeze the way Uji credits its river fog, which is an attribution rather than a measured effect. The plots are small and the ground awkward, so the district never went the way of the flat mechanised estates further south.
How it is made here
The defining step is the one left out. A sencha line finishes on a shaping machine that works the leaf against a heated bed until it forms straight needles, and tamaryokucha stops before that, tumbling in a drum drier instead, so the leaf sets into commas and hooks. Sonogi does this to steamed leaf, which is worth stating plainly because the identical shape is also produced by pan-firing over the prefecture line in Saga. Two separate teas end up looking the same in the bag.
What to look for
Sonogi and Ureshino make the same category on opposite sides of the same hills with a prefecture line between them, so a guricha with no town on it could be either: steamed here, historically pan-fired there. Ask for the town. Sonogi is sold as Sonogicha, as Higashisonogi and sometimes just as Nagasaki tea, and only the first two tell you anything. A competition result belongs to one lot from one grower in one year rather than to a region, whatever the shelf card implies.
