They are referring to a "shot" of espresso. The Italian standards are that it is a volume of 25 mL plus or minus ten percent. Additional shots in a drink indicate more espresso flavor and a higher caffeine content.

Though I don't generally like to cite Wikipedia as my primary reference, it does in this case have a pretty good overview of terms related to coffee extraction, re-summarized here: Extraction: The amount of the original mass of the grounds that ends up in the brewed coffee. Though it certainly depends on the preparation method ("method of extraction", e.g., ...

Yes, the term is an oxymoron. Miriam Webster agrees with your definition of brewing involving hot water: to prepare (as tea) by infusion in hot water That is why the word cold is used as a qualifier to show that it is done with cold water rather than hot water.

A "shot" in this context usually means one ounce, or so, of espresso. So a cup of coffee with two extra shots would be a cup of coffee with approximately two ounces of espresso added.

Brewing is a part of every coffee preparation method: it's the time when the water (or steam) is in contact with the grounds. It is a generic term. Percolation however, would only be used when making percolator coffee. You would not talk about percolation time when making espresso, for example. I would not use it as a generic term.

'Percolation' refers to any brewing process where constantly moving water passes through a bed of coffee in a filter. This water can pass through once (pour over, Chemex, batch brew etc) or multiple times (traditional percolator). Espresso is technically a percolation method. When coffee is left to steep in water it is known as immersion or infusion brewing. ...

In an academic article (in English language and authored by two Italian authors) espresso preparation is divided into these three steps: Grinding of the roasted coffee Coffee powder dosing and tamping Brewing (more correctly Percolation) In the rest of the document, percolation is preferred.

To me a percolator is a just a mechanism. You have a heater at the bottom, a tube, and a check value. The water enters the tube and some of the water is vaporized and it pushes the hot water to the top. They have no pump. That style of coffee maker is called a percolator. From there the term got used a lot ways.
