Grace Koshu 2024 connects a place, Katsunuma, with a grape, Koshu. They answer different questions about the wine.

The background that matters

This 2024 wine comes from Katsunuma vineyards above 400 metres and is fermented and matured in stainless steel.

Read it alongside this wine

Katsunuma tells you where; Koshu tells you which grape. The published review concerns this dry white, not every Japanese wine. The stated altitude belongs to the selected vineyards, not the whole district.

Try it with the review

Check aroma intensity, acidity and finish separately. Does a delicate nose necessarily mean a short finish? Write your answer using the review, and avoid treating the vineyard altitude as proof of a particular acidity.

These are learning prompts, not guaranteed tasting results. Separate the published facts from your own observations.

The bars compare annual rainfall; the coloured bands show the elevation range of each district.

  • Kofu basin: about 1,000 mm
  • Fuji Five Lakes and Fuji River basin (rainy districts): a little more than twice that
  • Shinonome (northern Katsunuma): 300–400 m (Mostly flat vineyards)
  • Yamato: 450–500 m (V-shaped valley with gentle slopes)
  • Sunshine and diurnal range — Around Katsunuma, long hours of sunshine and a wide diurnal range are conditions that suit grape growing.

Katsunuma: basin sunshine and diurnal range: A mountain-ringed basin, Alluvial-fan slopes and diurnal range, Humid summer and harvest timing → Vineyards

On the eastern rim of the Kōfu Basin, Katsunuma’s fan slopes combine long sunshine, a wide diurnal range and a humid summer that shapes Koshu.

  • A mountain-ringed basin — Katsunuma sits on the eastern edge of the Kōfu Basin. Ringed by mountains, the basin is known for long sunshine hours and comparatively low rainfall for Japan.
  • Alluvial-fan slopes and diurnal range — Vineyards on alluvial-fan slopes see warm days and cool nights; the diurnal range keeps Koshu’s acidity and delicate aromatics.
  • Humid summer and harvest timing — The rainy season and typhoons bring humidity; canopy work and harvest timing are part of Katsunuma’s terroir.
