A coffee Machine is a device used to prepare coffee beverages.

Adding coffee beverages to your menu can be an easy way to bring up your ticket average. Most customers who drink coffee do so after the meal and after they have already purchased another drink.

Coffee Bags

Coffee bags are a product designed for small volume operations. They are best suited for homes where the consumer drinks very little coffee or has very little space for a machine. They are also great for traveling or leaving in hotel rooms because no machine is needed. They are designed and used just like a tea bag.

Cold Brew

There are a variety of machines on the market for cold brewing coffee. These machines usually use no electricity and involve soaking the coffee grinds for 12 to 24 hours in cold or room temperature water until a flavor is extracted. The coffee resulting from this has a much milder flavor and is less acidic. It is better than regular coffee for people who have problems with heartburn. It is not a very popular extraction method.

Drip Brew

This is the most common method of brewing coffee. It provides a decent cup and is fairly economical. They consist of some form of heating element, a filter basket and a pitcher.

Espresso

Having an espresso machine can add countless drinks to your menu. Many coffee drinkers only drink espresso beverages now days. It is also one of the most expensive methods of brewing coffee and your staff would require extra training for it.

Instant

Instant coffee has a bad reputation in the coffee industry. It can be sneaked into recipes or hidden in a smoothie recipe, but even though the flavor is comparable to other methods, the aroma is lacking.

Percolator

Percolators were popular in the 1970s but were quickly replaced by the drip brewers. The coffee is exposed to higher heat then other methods and the water is exposed to the coffee multiple times. For these reasons, the coffee quickly becomes bitter from overextraction.

Press

A French press is one of the simplest coffee makers available. Coffee grinds are added to the bottom of the pitcher, then hot water is poured on top. You wait 4 minutes, then press the filter down to stop brewing.

Turkish/Greek

A method of preparing coffee where extremely finely ground coffee and sugar is added to a special pot called an ibrik. Water is added to the ibrik and it is placed over a stove to heat. The coffee is stirred once, then it is left to boil. After a while, it is slowly transferred into cups with care not to damage the foam. The last few sips of the coffee are usually not consumed because of the coffee grinds that settle to the bottom.

Vacuum

One of the older methods of brewing coffee. The brewer consists of 2 glass chambers, a heating source, and a tube with a filter. Water is added to the bottom chamber, coffee is added to the top one. As the water starts to boil, the steam pressure forces the water up the tube into the upper chamber where the brewing starts. When the heat is turned off, a vacuum forms in the bottom chamber and the water is returned.
This method produces a very clean coffee. No grinds are in the cup, no metallic flavors absorbed from the machine, and no oils lost from going through a paper filter. It has the added bonus of being an impressive centerpiece. The downsides to using this method is that they are expensive and break easily.
