“There is no ethical consumption under capitalism,” a famous socialist belief goes, but like many activists, Jo is trying to curb that. She marries her two conflicting passions, coffee and the environment, by establishing a vegan cafe that only serves plant-based drinks. If a customer so much as mentions dairy, they're humiliated before being kicked out of the place. It’s both impressively assertive and gratingly obnoxious, which is something you could also say about the tone the entire film strikes. It’s well-meaning in its attempt to shed light on the ongoing climate crisis, but rather tone-deaf in trying to place the blame on everyday consumers rather than large-scale corporations. The editing choices, while meant to be cheeky, also go overboard with the cuts and colors, making it more annoying than anything else. Which is a shame, because apart from a noble cause, Coffee Wars also has a funny script and engaging performances going for it. It also gives us an insightful look into the highly competitive coffee tournaments being staged around the world. If only Coffee Wars let things brew for longer, maybe removed some elements and expanded others—specifically, dwell more on the contradiction of wanting to change a system while participating in it—then it would’ve been even more enjoyable and educational than it is.
