If 3/4 of your drink is the mixer, mix with the best. We believe a spirit is only as good as the mixer it's paired with. That's why at fever-tree, everything we do starts and ends with taste. In our quest to create the perfect range of mixers, we have traveled to some of the most remote parts of the world in search of the finest ingredients - from the democratic republic of the congo to find quinine of the highest quality, to the ivory coast and india for our unique gingers. Are ingredients really worth going to such lengths for? we certainly think so. Charles & tim.
