Moreover, on the market, we have two popular types of caffeinated beer other than the one with coffee.

The first one is the chocolate beer. The real chocolate beer is the one that was fermented with cacao or chocolate. This type also has a little amount of caffeine in it. However, most chocolate beer does not contain chocolate but the chocolate taste comes from the way of processing the grains before fermentation, so it might not contain caffeine.

Furthermore, the other type is tea-infused beer. Since tea contains a small amount of caffeine, the tea-infused beer content of caffeine might be negligible. However, the method and the time of infusion pays a role.

Regarding the role and the effect of each component on our body and especially on our central nervous system, caffeine stimulates the secretion of specific neurotransmitters involved in making the person more alert, attentive and awake.

However, alcohol has an opposite role, it makes you sleepy, inattentive, and tired. When mixed, the caffeine reduces the effect of alcohol. Thus, following the intake of caffeine and alcohol at once, the person will be fully awake for that reason he will drink more.

Moreover, excessive alcohol intake is not advised since it has a major effect on health like liver diseases, obesity, mouth cancer, and so on.

The effect of mixing alcohol and caffeine does not only make you more awake but it can increase your blood pressure leading to heart attack and stroke. Thus, if a person has any heart problems it is better to avoid mixing them.

Furthermore, after drinking a deal of alcohol, people tend to drink coffee or a beverage rich in caffeine. In this case, coffee that is high in caffeine will wake you up but it will not reduce the concentration of alcohol in your blood.
