According to the USDA National Nutrient Database, an 8-ounce (237 ml) cup of coffee brewed from grounds contains 95 mg caffeine, whereas an espresso (25 ml) contains 53 mg.


A 2017 review of clinical trials found that drinking coffee is generally safe within usual levels of intake and is more likely to improve health outcomes than to cause harm at doses of 3 or 4 cups of coffee daily


According to Over 50% of Americans over 18 years of age drink coffee every day.

This represents over 150 million daily drinkers.


30 million American adults drink specialty coffee beverages daily; which include a mocha, latte, espresso, café mocha, cappuccino, frozen/iced coffee beverages.


Coffee is highly consumed worldwide and could have positive health benefits, especially in chronic liver disease


Coffee drinking seems safe within usual patterns of consumption, except during pregnancy and in women at increased risk of fracture



What Is Coffee?

Coffee is a brewed drink prepared from roasted coffee beans, the seeds of berries from certain Coffea species.

 Coffee drinks are made by brewing hot water (or much less commonly, cold water) with ground coffee beans



Types of coffee beans 

The are two main types of coffee beans:

Arabica Beans

Arabica beans consist of 0.8–1.4% caffeine

Coffea arabica accounts for 60% of the world’s coffee production

Arabica beans have a smoother taste with more acidity a richer flavor, and often considered superior



Robusta Beans

Robusta beans consist of 1.7–4% caffeine

The coffee prepared from robusta beans is less acidic, more bitter, and contains more caffeine


It is used primarily in instant coffee, espresso, and as a filler in ground coffee blends.


Roasted robusta beans produce a strong, full-bodied coffee with a distinctive, earthy flavor

Methods Of Preparation

Coffee preparation is the process of turning coffee beans into a beverage.

This process includes four basic steps:

  • Raw coffee beans should be roasted
  • The roasted coffee beans must then be ground
  • Ground coffee is then mixed with hot water for a certain time
  • The liquid coffee is separated from the used grounds.




Coffee Drinks

Coffee drinks are made by brewing hot water with ground coffee beans.

The brewing is either done slowly by:

Drip or filter

French press or percolator

The brew can also be done under pressure by an espresso machine

This type of coffee drink is called “espresso”

All coffee drinks are based on either coffee or espresso, in different strengths

Some drinks have milk or cream added, steamed milk, cream, plant-based milk, or foamed milk


There are several ways coffee is brewed.

These methods fall into four depending on how the water is introduced to the coffee grounds:

  • Decoction (through boiling)
  • Infusion (through steeping)
  • Gravitational feed (used with percolators and in drip brewing),
  • Pressurized percolation (as with espresso).


Electronic coffee makers boil the water and brew the infusion with little human assistance and sometimes according to a timer.

Some device grinds the beans automatically before brewing.

Brewed coffee contains the most caffeine 56–100 mg/100 ml

Instant coffee

Instant coffee, also called soluble coffee, coffee crystals, and coffee powder is a beverage derived from brewed coffee beans.

People quickly prepare hot coffee by adding hot water or milk to the powder or crystals and stirring




Advantages of instant coffee include:

  • There is a speed of preparation 
  • Lower shipping weight and volume than beans or ground coffee 
  • Instant coffee also reduces cleanup since there are no coffee grounds,
  • It has a lower environmental footprint than other preparation methods



How Much Coffee Caffeine Amount In Instant Coffee

Instant coffee Caffeine Amount is 26 mg per 100gm

The caffeine content of instant coffee is generally less than that of brewed coffee.

One study comparing various home-prepared samples came to the result that regular instant coffee (not decaffeinated) has a median caffeine content of 66 mg per cup




What is espresso?

Espresso is coffee of Italian origin, brewed by expressing or forcing a small amount of nearly boiling water under pressure through finely ground coffee beans.


How Much Coffee Caffeine Amount In Espresso?

Espresso Coffee Caffeine Amount /100gm is 212mg

Espresso has more caffeine per unit volume than most coffee beverages, but because the usual serving size is much smaller, the total caffeine coffee amount is less than a mug of standard brewed coffee

Espresso typically is made from a blend of arabica and robusta beans.

Generally, one uses an espresso machine to make espresso.

The act of producing a shot of espresso is often termed “pulling” a shot, originating from lever espresso machines

It requires pulling down a handle attached to a spring-loaded piston, forcing hot water through the coffee at high pressure.

Today, however, it is more common for the pressure to be generated by an electric pump.

An espresso machine brews coffee by forcing pressurized water near boiling point through a “puck” of ground coffee and a filter in order to produce a thick, concentrated coffee called espresso.

Espresso machines may be steam-driven, piston-driven, pump-driven, or air-pump-driven.

Machines may also be manual or automatic.





French Press

What is the French press?

A French press, also known as a press pot, coffee press, or coffee plunger, is a coffee brewing device

The modern French press consists of a narrow cylindrical beaker, usually made of glass or clear plastic, equipped with a metal or plastic lid and plunger that fits tightly in the cylinder and has a fine stainless steel wire or nylon mesh filter.


A French press is a tall, narrow cylinder with a plunger that includes a metal or nylon fine mesh filter. The grounds are placed in the cylinder, and off-the-boil water is then poured into it.

The coffee and hot water are left in the cylinder for a few minutes (typically 4–7 minutes).

The plunger is gently pushed down, leaving the filter immediately above the grounds, allowing the coffee to be poured out while the filter retains the grounds.

Depending on the type of filter, it is important to pay attention to the grind of the coffee beans, though a rather coarse grind is almost always called for

Coffee is brewed by placing coarsely ground coffee in the empty beaker and adding hot—between 93–96 °C water, in proportions of about 30g of coffee grounds to 500 ml of water, more or less to taste.

The brewing time is about two to four minutes.

A French press works best with coffee of a coarser grind

French presses are more portable and self-contained than other coffee makers



How Much Coffee Caffeine Amount In The French press

French press coffee contains a jitter-inducing 107.5mg per 8 ounces cup.

This actually makes a cup of French press coffee more caffeine-rich than one small shot of espresso.



What is Turkish coffee

Turkish coffee is coffee prepared using very finely ground coffee beans, unfiltered.

Any coffee bean may be used; arabica varieties are considered best, but  Robusta or a blend is also used.

The beans must be ground to a very fine powder, which is left in the coffee when served

Turkish coffee is made by bringing the powdered coffee with water and usually sugar to the boil in a special pot

As soon as the mixture begins to froth, and before it boils over, it is taken off the heat.

It may be briefly reheated twice more to increase the desired froth.



How Much Coffee Caffeine Amount In Turkish Coffee 

Turkish Coffee contains 25.00 mg of caffeine per fluid ounce (84.54mg/100 ml)



Drip brew coffee

 What Is Dip Brew Coffee?

It is also known as filtered coffee

Drip coffee is made when you allow hot water drip through coffee grounds held in a coffee filter surrounded by a filter holder or brew basket.

Drip brew makers can be simple filter holder types manually filled with hot water, or use automated systems as found in the popular electric drip coffee-maker.

Strength varies according to the ratio of water to coffee and the fineness of the grind.

It is weaker in taste and contains a lower concentration of caffeine than espresso, though often (due to size) more total caffeine


How much Coffee Caffeine Amount In Drip brew coffee

Drip or filter coffee has a median caffeine content of 112 mg, with a median concentration of 621 µg/ml for the same cup size




What is a cappuccino?

A cappuccino is an espresso-based coffee drink that originated in Italy 

It is traditionally prepared with steamed milk foam.

Variations of the drink involve the use of cream instead of milk and flavoring with cinnamon or chocolate powder.
