Kumamoto vs Miyagi
Both of these West Coast favorites trace their ancestry to Japan, yet they are different species with distinct personalities. The Kumamoto (Crassostrea sikamea) is a small oyster from the Pacific Northwest with sweet and melon primary flavors, a sweetness of 4, a low brininess of 2, and a clean, lingering finish with gentle sweetness. The Miyagi (Crassostrea gigas), grown on the US West Coast, is medium-large and meatier, leading with nutty, crisp, and briny notes at a brininess of 3 and a sweetness of 3, finishing clean and crisp with lingering fruit and vegetal hints of lettuce and melon rind. Both are deep-cupped, creamy (4 out of 5 each), and beginner-friendly. The Kumamoto is the sweeter, gentler bite; the Miyagi is fuller-bodied and more balanced, with a touch more salt and a distinctive nutty streak.
