W5 Collective, London’s first climate positive restaurant, is marking the occasion by giving away free Espresso Martinis this week for the first twenty customers who say ‘plant me a tree.’ They are also running a 2 for1 offer on its planet-friendly signature cocktail, the Espresso Mar-tree-ni for those who miss out on a freebie, running from Thursdays through to Saturdays between 5pm and 8pm from 25 November to the 4 December 2021. This much-loved drink is made combining espresso straight from the machine, FAIR Café liquor and British Sapling vodka. Coffee is sourced from a single farmer in Brazil helping to maintain a consistently excellent product and support local farming communities. For each cocktail sold, W5 Collective plants a tree in countries experiencing deforestation, like Madagascar, Brazil, Colombia, and Indonesia, to restore and grow healthy forests and help to combat climate change.
