If you enjoy coffee, you've probably wondered how many distinct varieties of coffee beans there are and what distinguishes them. Some may also go further and ask, “What is the difference between arabica and robusta coffee?” Let’s learn how these unique coffee bean types are produced and what coffee bean nutrients are behind their remarkable health benefits.

All about coffee beans and their benefits


A coffee bean is a seed that grows inside the cherry [fruit] of a coffee plant. We don't consume the outer part of the coffee cherry. Instead, we remove the pit and roast it. Arabica, Robusta, Liberica, and Excelsa are the four major varieties of coffee beans. Arabica and Robusta are the most prevalent, but you might get lucky and come across the other two as well. You may be aware of the various varieties of coffee beans. However, do you know what distinguishes each sort of bean? This blog post will look at the various varieties of coffee beans and what distinguishes them from each other.


  1. ARABICA COFFEE BEANS: - Considered the most popular coffee bean type, Arabica beans account for over 60% of the world's coffee market . This coffee bean is generally used to make decaf or black coffee, and the most intriguing aspect is that it contains less caffeine than robusta coffee beans. Arabica coffee beans can be either mildly roasted, medium roasted, or dark roasted.
  2. ROBUSTA COFFEE BEANS:- Robusta is the second most popular type of coffee bean. Because Robusta coffee beans have more caffeine than Arabica beans, they are frequently used in espresso blends. This additional caffeine imparts a more intense flavour and a higher level of acidity to the coffee. Some people report experiencing effects like insomnia and headaches when they consume robusta in large quantities. Hence, it should be enjoyed in moderation.
  3. LIBERICA COFFEE BEANS:- Liberica coffee beans are substantially less prevalent than the two varieties of beans mentioned above. They have a distinct aroma that is described by many as smoky, flowery, and fruity. The Liberica bean is a coffee bean native to Liberia, which is located in West Africa.
  4. EXCELSA COFFEE BEANS: - Excelsa is the fourth primary type of coffee bean. However, the Excelsa coffee bean, like the Liberica coffee bean, is considerably less widely used to manufacture commercial coffee. Excelsa coffee beans are medium to dark roasted and have a rich and powerful flavour. It carries a chocolate and caramel like aroma with a tint of acidity that creates a good balance.


Coffee’s amazing health benefits are directly associated with numerous coffee bean nutrients present in abundance in it.

  1. Coffee beans are a good source of caffeine, plant polyphenols, vitamin B2 and magnesium.
  2. Roasted coffee contains a complex mixture of approximately 1000 bioactive compounds, some of which can have antioxidant, anti-inflammatory, anti-fibrotic and even  anticancer properties.
  3. Coffee can contribute more antioxidants to your daily diet than tea, fruits and vegetables.

POINT TO REMEMBER:- Recent studies show that coffee consumption is absolutely safe for healthy, non-pregnant women when drunk in moderation. On an average, three to four cups of coffee per day supply 300 to 400 mg/d of caffeine.


While drinking too much coffee might cause health problems such as digestive disorders, contemporary studies show that drinking up to four cups per day is considered safe. Furthermore, coffee can be beneficial to your health in a variety of ways due to the antioxidants and minerals included in all varieties of coffee beans. Coffee's biochemical content is determined and assessed by the degree of roasting, the kind of bean, and the coffee brewing process, including grind type. No matter how big a fan you are of coffee, always try to consume it in moderation. You can also try this delicious mint coffee milkshake at home.
