FIELD NOTE 01
From north to south, first place seven points
Check Hokkaido, Yamagata, Niigata, Nagano, Yamanashi, Osaka, and Tsuno in Miyazaki on the map. These are the main entry points for learning, not an official ranking of prefectural production or a complete list of wine regions. Hokkaido's coolness and Nagano's high altitude both help preserve acidity, but they arise from different conditions.
FIELD NOTE 02
Read the varieties as they correspond to the land.
Expanding from Koshu and Muscat Bailey A, include Hokkaido’s Kerner and Pinot Noir, Nagano’s Merlot, and Kyushu’s Chardonnay. Even within the same country, adaptation to cold winters, length of growing season, and rainfall response differ. Instead of deciding flavor solely by the variety name, reading the harvest time, training system, and vineyard site deepens understanding of the region.
FIELD NOTE 03
Moving between vineyard and label
The term 'Japanese wine' indicates requirements relating to ingredients and domestic production. Check separately for geographical designation, variety, vintage, and GI. A Japanese producer does not guarantee that all ingredients are locally sourced, nor does use of Japanese-grown grapes guarantee a GI label. Go from an overview to each region, and compare, using specific products, lees aging in Koshu and red blends at the end.
For Hokkaido, consider northern latitude; for Nagano, high altitude and inland terrain. Each area still has variation within itself.
