The surge in coffee prices to the highest level since 1977 could force more consumers to save money by making their daily brew at home, in a boon for ASX-listed small appliance maker Breville.

That is according to Citi analysts who warned the rally in arabica futures, which hit a 47-year high of $US3.35 a pound on Friday, will result in higher costs for cafes that would likely be passed on to consumers. Nestlé, the world’s biggest coffee maker, said last month that it would raise prices and make packs smaller to blunt the impact of the more expensive beans.
