The core of coffee's alertness-boosting effect lies in caffeine, but different coffee bean varieties and extraction methods can cause significant differences in the caffeine content of the final drink.

Espresso may seem intense, but its caffeine content is not necessarily the highest; pour-over, French press, cold brew, and ice drip often contain more caffeine due to longer contact time. From the perspective of Front Street Coffee, this article systematically sorts out coffee bean varieties, extraction methods, and the caffeine content of common drinks, helping you choose the most suitable stimulating coffee for yourself in different scenarios.

Many people choose to drink coffee with the core desire of consuming caffeine. Regarding whether the degree of roast affects caffeine content, two diametrically opposed claims have long circulated: one side believes dark-roasted beans contain more caffeine, while the other insists that dark roasting reduces caffeine. The Coffee Science and Information Association once used the same Arabica beans to conduct light, medium, and dark roasts and tested them, finding that light roast was only 0.06 percentage points higher than dark roast. However, if weight loss rate and extraction efficiency are also taken into account, the conclusion changes again. The real key determining caffeine content actually lies in the bean variety itself. This article will break down these variables layer by layer to help you clarify the true relationship between roast level and caffeine. [more…]

In the world of coffee, Arabica and Robusta are the two most common bean varieties on the market. The former is a small-seeded species, while the latter is a medium-seeded species, and the two differ noticeably in caffeine content, flavor profile, growing conditions, and appearance. Arabica has lower caffeine and higher sugar content, with a sweeter, softer flavor and fruity acidity; Robusta, on the other hand, has higher caffeine, chlorogenic acid, and amino acid levels, giving it a richer, deeper, low-toned mouthfeel.
