Brewed Coffee

If you are a coffee lover, you may be familiar with brewed coffee as it is one of the simplest coffee types. You can have a cup of brewed coffee just by pouring boiling water onto coffee grounds in coffee filters. A cup of brewed coffee is served in an 8-fluid ounces cup equal to roughly 95 mg per cup.

Cold Brewed Coffee

Brewed coffee also comes in various types, one of which is cold brewed coffee. Some may think cold brewed coffee is just hot brewed coffee with ice, but it is not the case. Cold-brewed coffee is made by soaking the coffee beans in room-temperature water for about 10 to 20 hours. After that, you strain the coffee grounds out and let it chill before serving; it can be served with ice or no ice. As it is kept in water for a long time, it extracts more caffeine from the coffee, making it more flavorful, smooth, and less acidic. It is served in a 12-fluid ounces cup equal to 200 mg per cup.

Decaf Coffee

Decaf coffee is a shorter version of decaffeinated coffee in which the caffeine content in coffee beans is extracted using different methods, including water, carbon dioxide, and organic solvent. This type of coffee has about 97 percent of its caffeine content removed before roasting and grounding. Hence, it is expected to have less caffeine than other coffee once served, about 3 to 4 mg per 8 fluid ounces cup.

Drip coffee can be made within 3 to 10 minutes, according to the number of grounds. It is known to have high caffeine. For instance, an 8 ounces cup has approximately 115 to 175 mg of caffeine.

Highly Caffeinated Coffee

Nowadays, there is a trend in coffee with a huge amount of caffeine content, which are the Deathwish coffee and Biohazard coffee, which contain 700 to 900 mg of caffeine per cup of 12-fluid ounces. The reason behind the high caffeine content is that these coffee are made of Robusta coffee beans which are naturally 2 or 3 times more caffeinated than regular Arabica coffee beans. Coffee and caffeinated drinks with this high caffeine content are trending through various social media platforms and receiving much attention.

Are Highly Caffeinated Drinks Safe? What about 800 mg and above?

Frankly speaking, highly caffeinated drinks are not safe. Although coffee has benefits, it is only beneficial once consumed in moderation. A correct and safe daily caffeine intake is only up to 400 mg for healthy adults without any side effects, approximately 4 cups of brewed coffee. Hence, 800 mg is too much and unsafe for you. For most people, up to 200 mg is considered safe. Something above 400 mg per day is unsafe, which causes several side effects that can be major in the future.

The increase in blood pressure poses an increased risk of stroke and heart attack and affects blood flow in our heart and brain. Also, some may experience rapid heart beating when drinking too much coffee. It is noted that caffeine can also raise your heart rate and can turn to heart failure when consumed too much.
