An espresso needs to be drunk nearly immediately after preparing, after which it rapidly starts to lose quality up till a point where it is undrinkable and deemed dead. Is this real of incorrect?
Does espresso coffee "expires"? And what does a dead espresso even mean?
It looks like the dead espresso shot started within a coffee chain which must remain unnamed, but they are renown for their under-average espresso shots. Throughout the training the brand-new baristas are told that shots pass away after 10 seconds, so they require to utilize those shots in a coffee drink, or serve it to the customer within 10 seconds from puling. Individuals took this literally and out of the context and the dead espresso shot misconception was born.

Certainly, perfectionists from the Italian tradition will argue that an espresso is optimum and must be drunk about ten seconds after brewing. This time frame is a bit ludicrous and impractical, typically resulting panic, coffee spillage and burned mouths.
Let's look at a more practical time frame: 1-3 minutes. This is the time it takes for the crema to disappear from the top of a (usually) well made espresso. Crema is the layer of foam that typically sits on top of an espresso that has just been pulled. When water and oils from the coffee mix and come together with CO2, it is produced. The typical rule in coffee making is that when the crema vanishes from an espresso, the shot is dead. Where does this rule originated from and is there any reality in it?
Crema contains no real taste in itself. The factor 'dead' espresso shots are linked to crema is that this layer of foam really works as a brief protective barrier versus oxidation.Oxford languages describe oxidation as the chemical reaction of any compound with oxygen. Oxidation is why we cover all of our fresh food in saran wrap or keep them airtight in some way. , if we do not the food starts to go stagnant quicker
The same holds true for coffee. When coffee enters into contact with air it starts to decay. Regrettably, the speed at which this takes place is hugely accelerated when we heat and grind coffee. This is why two important components for a fantastic cup of coffee are recently roasted and newly ground beans.
It is generally suggested, therefore, that we take in a brewed cup of coffee within 30 minutes of making. Hang on: why does a typical cup of coffee or an Americano stay fresh for 30 minutes when an espresso loses its freshness after 3 minutes?
