Koshu Grape Seedss 100 pcs (Vitis vinifera) Vines Table Grape

Koshu Grape is a historic Japanese grape variety traditionally cultivated for premium white wine production, valued for its subtle elegance and terroir expression. It is believed to have ancient genetic roots linked to Eurasian grape lineages, resulting in strong adaptability to humid and variable climates. The vine shows moderate vigor with balanced growth, making it suitable for careful canopy management. Berries develop with a distinctive pale pink to light lavender skin, a rare trait among white wine grapes. Koshu is especially prized for its ability to retain high natural acidity even at full maturity. The flavor profile is delicate rather than bold, emphasizing clarity and finesse over intensity. Wines produced from Koshu are typically light-bodied with refined aromatics and a clean finish. The variety performs well in regions with warm summers and sufficient rainfall when managed properly. Its disease tolerance is moderate, requiring preventive viticulture in humid environments. Koshu holds strong cultural and commercial value in niche international wine markets focused on elegance and food-pairing versatility.
