Nigori is the unfiltered version of Japanese umeshu, a popular liqueur made with macerated ume fruit. Standard umeshu is produced by macerating ripe or green ume plums and sugar in neutral spirits, most commonly shōchū. Although most umeshu is filtered before consumption, some homemade and commercially produced versions skip this step, which results in a cloudy liqueur with a distinctive texture and a fruity, mellow flavor.
