> which is why spray drying remains the dominant method I don't think I've ever seen spray-dried. Even the cheap supermarket instant coffee is mostly freeze-dried in the UK I believe. You can really see the power of marketing at play in instant coffee. A lot of 'premium' branded instant coffee is ~£42/kg. That's £3/kg more than my premium, locally-roasted, single-estate Colombian coffee beans. If you have more money…
You need 7-10 times less instant coffee to make a cup though, so your beans are a lot more expensive in the end. From my experience, cup of coffee is either 2 grams of Nescafe Gold or 16 grams of beans.
