The coffee machines only flash-heat the amount of water needed for one portion, unlike, for example, boiling a kettle. Capsules, on the other hand, are more efficient. That’s why barista-made espresso fares so badly in terms of its environmental footprint: a lot of energy is needed to brew just a tiny single espresso cup. Aside from the environmental impact of growing beans in the first place, the second biggest hit is the energy it takes to brew coffee. Hill's research backs up other studies conducted during the past few years, which suggest that capsules are environmentally less harmful than alternative coffee-brewing methods. Maxwell Colonna-Dashwood, a barista and co-owner of Bath-based specialty coffee shop Colonna & Small’s, who collaborates with researchers, says that “instant coffee extracts a lot from the bean, so uses less coffee per cup,” although he adds that it’s not necessarily performing well on other aspects of sustainability.
