Most guests are familiar with Midori Melon Liqueur, the ultra sweet, bright green, muskmelon-flavored elixir made popular in bars and discos in the 1970s. But a few new Asian liqueurs are making a splash behind the bar. TY KU Citrus Liqueur blends Soju with traditional Asian ingredients including yuzu, mangosteen and ginseng, as well as goji berry and honeydew. Wynn Las Vegas’ Japanese restaurant Okada serves it in the Kiwi Lemonade ($14), where it’s mixed with 42 Below Kiwi Vodka, fresh kiwi and house made sweet and sour. ZEN Green Tea Liqueur is crafted from neutral spirits infused with Kyoto green tea leaves, then blended with herbs including lemongrass—it’s earthy, sweet and just a touch bitter. Cocktails like the ZENtini brighten that earthiness with citrus vodka and fresh lime; serving it over the rocks with a splash of cream gives it a flavor profile not unlike green tea ice cream. Patricia Richards, property mixologist for Wynn Las Vegas, predicts that exotic flavors from around the globe will continue to find themselves in liqueur bottles on bar shelves.
