While coffee is easily one of the world's most popular drinks, it's particularly popular amongst students who drink it in order to focus and concentrate better. For many students who burn the midnight oil in order to finish that paper, a cup of Joe is invaluable. But did you know that the caffeine content of coffee varies depending on several factors? The type of coffee beans, the roasting process, the type of coffee, and the serving size all play a part. That being the case, here are some facts that can help you to choose the right coffee to maximize its benefits on your memory.
Types of beans – Arabica and Robusta
There are many types of coffee beans, all of which contain different amounts of caffeine. Arabica and Robusta are the two most commonly known types. Arabica beans are expensive and mainly used in gourmet brands because of their sweeter, smoother, and more complex flavor profile. They are usually less bitter than their Robusta counterpart.
Robusta beans are hardier, harsher and bitter. The plus side is that they have significantly more caffeine than Arabica.
If you want good flavor and don’t mind a more expensive coffee, look for a bag of 100% Arabica. If you want more caffeine and need to save money, try out Robusta or a blend of Arabica and Robusta.

Effect of Coffee on Students' Study
It's no shock that students often consume coffee while studying because caffeine helps to keep them alert. Balanced caffeine intake helps invigorate students and gives them just the right amount of energy to finish those last-minute papers. Too much caffeine can have counter-productive effects. Caffeine will help keep you awake but it obviously won't write the paper for you. Fun fact, you may be surprise to know that these days students can ask professionals to “write my college paper” while they enjoy a cup of coffee. Professional help through an online essay service can do wonders for school and college students.
Roasting Process – Dark Roasted or Light Roasted
Researchers at the Krembil Brain Institute in Toronto, Canada, have been studying how coffee can protect the brain and improve thinking skills. What they discovered is that the benefits may lie in the roasting process of the coffee beans which has a direct impact on the caffeine content. They looked at caffeinated dark roast, decaffeinated dark roast and caffeinated light roast.
Lighter roasts usually contain more caffeine than dark roasts. Dark roasted coffee, whether caffeinated or decaf, seemed to have the strongest protective effect on the brain. It could help to prevent people from developing neurodegenerative diseases like Parkinson’s and Alzheimer’s.
Type of Coffee – Espresso, Instant etc.
The caffeine content can vary a great deal between regularly brewed coffee, instant coffee, decaf coffee and espresso. An average cup of regularly brewed coffee will generally provide you with around 95 mg of caffeine.
In a double-blind study by John Hopkins University, one group of participants took a 200-milligram caffeine tablet, and the other group didn’t. After studying a series of images, the caffeinated group was more adept at picking the correct images out from similar images when tested the following day.
How much coffee you consume
A 2016 study from the University of Ulster in the U.K. found that the benefits of moderate coffee consumption outweighed any potential risks. Drinking too much coffee can cause sleep problems, heart palpitations or muscle tremors. It is recommended that a human drink no more than 400mg of caffeine per day. If you love the taste of coffee but don't want the caffeine, consider trying decaf.
Nootropics or ‘smart’ drugs are becoming more popular. Various coffee brands such as VitaCup exist today that include natural brain-enhancing substances. They claim to increase energy levels and aid in concentration without having any of the negative side effects of drinking regular coffee. Unlike drugs, nootropics are safe and help to protect the brain. They are completely legal, and they can improve focus and enable clarity of thinking.

There are different options for nootropic infused coffee – from instant coffee to the whole bean. They often contain amino acids like Alpha GPC, Taurine, and L-Theanine, which may be hard to get from food sources alone.
One thing to note about the best vitamin coffees available is that they do NOT taste like vitamins. Any coffee lover is likely to baulk at the idea of vitamin and coffee in the same cup. But rest assured, the top brands have invested much research, time, and money into a formulating a product that's as tasty as it is healthy.
In summation, the effects of coffee on your concentration and memory will depend on many different factors such as bean type, roast, and quantity. In the end, remember to be aware of how many cups you actually drink. Many coffee lovers know it's easy to lose track especially if you're “running on empty”. Take care of yourself and remember not to drink more than 400mg of caffeine per day. If you're on a real time-crunch and need to stay awake, consider some of these coffees branded for high caffeine content.
