Water & Climate

Ask about Kavalan's water source, and you get an answer that sounds like mountains. The water comes from the Xueshan massif, at 3,886 meters Taiwan's second-highest peak. It seeps as meltwater and rainwater through rock and scree. Only after a long underground journey does it reach the Lanyang Plain.

On its way through gravel and sand, the water loses its hardness. In the end, Kavalan draws it from a twenty-five-meter-deep well on its own grounds. It is soft, nearly neutral in pH, and contains seventeen to twenty milligrams of calcium per liter, somewhat more minerals than typical Scottish brewing water. Even so, it never feels hard.

Yilan lies in Taiwan's subtropical northeast. Summers are hot and humid, and rain rarely lets up throughout the year. Temperatures regularly climb above thirty degrees Celsius in summer. This humidity fundamentally distinguishes maturation here from the cooler, drier air of Scottish warehouses.

Warmth and humidity together mean the whisky interacts far more intensely with the cask wood than would be possible in cooler latitudes. Just how strong this effect is becomes clear in the warehouse, where the actual maturation takes place. But the soft water already lays the groundwork. Without hard minerals that could mask aromas, the character of malt and cask comes through more clearly.

The distillery's own well makes Kavalan independent of fluctuating surface rainfall. Whether a rainy season turns out especially wet or dry, the groundwater from deep below stays at almost the same temperature and softness all year round. This consistency matters more, for a distillery that mashes daily, than any single rain cloud over Yilan.
