Lauren Mote, Diageo’s Global Cocktailian, who is travelling the world judging local editions of World Class Best Bartender of the Year 2018, writes on what it takes to create a more environment-friendly bar program  and the use of root-to-tips of a plant to create cocktails. Mote won World Class Canada back in 2015. The 2018 winners will go on to compete in Berlin later this year.
