Shake once without ice and once with ice, strain into a cocktail coupe, and garnish with freshly grated nutmeg.
After reading about a Fino Flip, I was tempted to make that style of Sherry Flip (I have had ones with other sherry types). Instead, my mind drifted to the Bamboo Cocktail, and I wondered what a Bamboo Flip would be like? Once assembled, it met the nose with nutmeg and a savory wine note from the Fino and perhaps the vermouth. Next, a creamy and clean sip was followed by a sake-like swallow with a hint of orange, spice, and herbal accents. The rice wine flavor seemed to tie back into the 1890s Japanese origins of the Bamboo Cocktail at the Grand Hotel in Yokohama.
