Umami means as much as all the senses. The manufacturers from England have set themselves this task. The new Senses Liquide come straight from the Six Licks kitchen. All of your senses are used here. Senses by Six Licks - Rhubellion Liquid is a fresh, tasty rhubarb with a nice, sour, tangy, green apple. A wonderful game of sweet and sour flavors.
