The coffee category grew by 4% in volume terms in 2015 due to a number of factors such as continued increases in disposable income, new product developments (such as Nescafé Dolce Gusto and Nespresso pods by Nestlé de Colombia) and promotional campaigns to increase domestic consumption (such as those conducted by the Toma Café Program). During 2015, the Colombian economy showed positive growth similar to that observed during the review period, which allowed for an increase in the consumer base for coffee given the increasing size and purchasing power of the middle class. Retail value also expanded by 8% in current terms in 2015 as average unit prices rose by 4%.
