Roasted beans are ‘fresh’ when they emit a high concentration of CO2 or carbon dioxide. The process of grinding beans further releases this element, and it is what later interacts with other elements in the brewing process.
Crema' is often mentioned with reverence in relation to espresso. It refers to the light-coloured layer that forms on the surface of brewed coffee during the extraction stage.
When brewing always look to see how much Co2 is being dispensed it will give you a good indication of fresh the coffee grounds are.
We roast every other day. You will be getting fresh coffee from us.
Happy Brewing.
