No. An espresso is a concentrated, often thick coffee beverage with a layer of dense foam whose ingredients are exclusively coffee and water, created with a machine that forces hot water through a basket of tightly packed, finely-ground coffee for a limited amount of time at very high pressure. Stumptown say:
“Espresso is using nine bars of atmospheric pressure and a highly calibrated piece of equipment to force water over 24-27 grams of coffee to yield a concentrated beverage that can taste really good.”
The critical bit is the ‘nine bars of pressure’.
It’s the immense pressure which pushes the hot water through the grounds which creates the crema and the richness of the coffee, as well as the precision timing of the water being pushed through the water at a certain rate, the grind of the coffee not allowing it to dash through too long, and many other variables.
If you were to simply mix grounds and hot water together, this would be an immersion coffee – similar to a french press. You’d also have the issue of filtering the coffee grounds out of the coffee once you’d mixed it up.
The closest you might be able to get (and it is not an espresso, but it does combine immersion and pressure methods) is an Aeropress . You mix the coffee and water in a chamber, and then push it out through a filter. It makes a much stronger coffee than something like a V60 pourover method – and many baristas will swear by the Aeropress making one of the best cups about. I take my aeropress on holiday with me whenever I travel, so I can always guarantee a decent cup of coffee.
Did a quick read, and your answer is, HELL NO, your way, is just chilled coffee or cold brew.
So drink away please???
No. You’re going to end up with a sludgy mess.
Consider first, the ratio of water to coffee. There’s no way to shake them together and get any meaningful extraction out of them. The water isn’t going to interact with the coffee enough.
Second, how do you get the water out of the sludge? You could let gravity do its work and hope to filter out the wet grounds, but you’re still not going to get anything but really bitter water.
Espresso relies on the pressure of the hot water forcing its way through the grounds to extract flavor. The pressure and high temperature create extraction in a fraction of the time it takes for a drip machine to do it.
So, no. You can’t make espresso. You can, however, given enough coarsely ground coffee and water, make an excellent cold brew.
