Coffee beans and brewing methods have a big impact on caffeine content. The type of bean, the roast, the grind, and the brewing method all affect how much caffeine ends up in your cup.
Light roasted beans have more caffeine than dark roasted beans. This is because the roasting process breaks down some of the caffeine. So, if you’re looking for a caffeine boost, go for a light roast.
A coarse grind will have less caffeine than a fine grind, because more of the surface area of the beans is exposed to water. This means that more caffeine is extracted. So, if you want less caffeine, go for a coarser grind.
The longer your coffee brews, the more caffeine is extracted. This is because the longer the beans are in contact with water, the more caffeine is released. So, if you want more caffeine, brew for a longer time.
Cold brew coffee has less caffeine than hot brew coffee. This is because the brewing process is slower, so less caffeine is extracted. If you want more caffeine, go for hot brew coffee.
The type of bean, the roast, the grind, and the brewing method all affect the caffeine content of your coffee. So, if you’re looking for a caffeine boost, light roast, fine grind, and long brewing time are your best bet.
