Recent price increases may make this daily staple nearly a luxury," Eurostat warned, revealing that coffee costs increased 16.9% year on year in August. According to Eurostat, fresh whole milk now costs 24.3% more on average, while fresh low-fat milk costs 22.2% more.
Aside from that, the caffeine level of coffee varies according to altitude and brewing style, to mention a few factors. Throughout the market and industry, much has been learned about flavour profiles, roast types, origin, bean and grind uniformity, and so on. In this post, we will look at the various brewing techniques that affect the caffeine concentration of your coffee.
Brewing Method Coffee
When a caffeine boost is required to get through the day, many people turn to an espresso shot. However, because to the reduced serving size, it has less caffeine than a standard cup of coffee. Caffeine levels in a single 1 oz. shot of espresso from a coffee machine range between 30 and 50 mg. If you're looking for a caffeine boost, go for a double espresso shot.
The two most frequent methods for making filter coffee are pour-over and drip. These techniques ask for medium- to fine-ground coffee to guarantee that coffee flavours are progressively released as water passes through the grounds. Caffeine levels in a standard cup of coffee prepared using the filter coffee technique range from 60 to 100 mg. Keep in mind that more caffeine will be extracted from finer grinds and hotter water, resulting in a strong and bitter flavour.

The temperature of the water has an important effect in the extraction process. Because cold brew is an under-extraction technique, you only extract 75 to 80 percent of what you would with a hot brew method. To compensate for a slightly lower temperature in a cold brew, it is recommended to increase the brewing time and avoid using an exceptionally fine grind size. To lower the caffeine content, milk or water are usually added to cold brew.
Despite the fact that it is an immersion process and uses very hot water, the French Press brewing technique does not produce particularly high extractions. The extraction process is primarily influenced by two factors: the temperature of the water and the coarseness of the ground coffee. Because the coffee ground with the French Press process is coarse rather than fine, the extraction is not optimal. However, if you use finely ground coffee, your cup will include a lot of coffee grounds, which you should absolutely avoid.
The AeroPress is a manual coffee brewing gadget that was invented in the United States in 2005. It has since become a coffee lover favourite because it provides the richest and smoothest brews. When you press down on a plastic plunger filled with coffee grinds and around 225 ml of hot water, it produces a cup of strong, smooth coffee. This is why it is called an aeropress. It is usually stronger than normal coffee. The caffeine level of an AeroPress coffee cup ranges from 50 to 70 mg.
