Wave Train sits at the lighter end of Nepomucen's rotating sour range. The fruit additions, pineapple, ginger and lime, place it in tropical territory, more sprightly than the berry-heavy Frutollo or the more complex Free Pan Da. In the glass, hazy golden-yellow. Pineapple leads the nose with fresh immediacy, joined by the sharp, bright note of lime. Ginger is subtle on the nose but builds on the palate, adding warmth and a spicy edge that carries through to the finish. The lactic sourness is clean and measured, keeping things tart without tipping into sharpness. Coconut appears in the background as a soft, rounding note. Low carbonation, light body. The ginger gives it more personality than a straightforward fruit sour.
