As coffee lovers, many of us are curious about the caffeine content in our coffee. However, with so many variables in brewed coffee, it can be challenging to estimate the amount of caffeine we consume accurately.

If you’re looking for a quick and straightforward way to estimate the caffeine content in your coffee without specialized equipment, here’s a method you can use.

  • Weigh the Dry Coffee: Start by weighing the dry coffee grounds you plan to use. For accuracy, use a kitchen scale that can measure in grams.
  • Caffine Estimation: Once you have the weight of the dry coffee, you can estimate the caffeine content by multiplying the weight (in grams) by 0.008. For example, if you have 10 grams of dry coffee, the calculation would be: 10 g×0.008=0.08 g (or 80 mg).
    This means that 10 grams of dry coffee typically contain about 80 milligrams of caffeine.

Understanding Caffeine Extraction

It is important to know that the caffeine content can vary based on how the coffee is extracted during brewing. Here’s a breakdown:

  • Weakly Extracted Coffee: This type of coffee may yield approximately 0.6% of its weight in caffeine. Weak extraction usually occurs when the brewing time is short, the water temperature is low, or the grind size is…
