7/21/2023 0 Comments Espresso shot![]() This is arguably only the start of the “stale journey” so there is theoretically still some flavor to be had from a coffee, even at that stage in its life. In fact, another time frame that is discussed with regard to coffee deterioration is fours hours, at which point the oils in the coffee start to go bad. This is because different properties of the coffee are released at different stages after the coffee has been brewed. Indeed, coffee tasters will often allow coffee to cool as they are tasting it. However, cold doesn’t mean stale and the two coffee states have been confused with one another in recent times. This is because we are expecting something different to what we taste. ![]() If we are supposed to drink espresso before the crema disappears because the crema protects the coffee from the air and oxidation, then logically espresso will only start to “go stale” or rather to oxidize, at the 3-minute mark, not before it.Ĭulturally, when we brew hot coffee it is not a nice experience drinking it after it has gone cold. A big cup of coffee that has a lot more hot water will take a lot longer to go cold, say 30 minutes when exposed to the air. An espresso is a small drink with a small amount of mass. Stop The Shot Early This is the same process as pulling regular shot. The real reason behind this double standard is that coffee drinkers are too focused on the crema rule, while the real reason they feel the espresso stops becoming palatable is that it goes cold. Method one: stop your espresso shot before you normally would Method two: pull one ml of liquid per second using a 1:1 ratio Method three: Use finer grinds for a longer extraction Let’s examine each method in greater detail.

Something feels off here. The reason is that, after this time, coffee is said to be stale. It is generally recommended, therefore, that we consume a brewed cup of coffee within 30 minutes of brewing. This is why two very important ingredients for a successful cup of coffee are recently roasted and freshly ground beans. Unfortunately, the speed at which this happens is hugely accelerated when we heat and grind coffee. When the coffee comes into contact with air it starts to decay.
