The caffeine content in a cup is not a universal value; it is the result of an equation involving botany, chemistry, and heat. On average, a standard espresso contains between 60 mg and 80 mg of caffeine. If you prefer a domestic moka pot, the values rise to between 100 mg and 120 mg per cup due to the prolonged contact time with water.
How much caffeine does a coffee really contain?
Caffeine content is not a fixed value, but depends on several factors:
- Brewing Method
- Amount of coffee used
- Botanical variety
Average values per cup
| Method | Caffeine (mg) | Notes |
| Single espresso | 50–70 mg | High concentration |
| Double espresso | 80–120 mg | Larger dose |
| Moka | 100–120 mg | Higher total amount |
| Filter coffee | 80–120 mg | Higher volume |
| Decaffeinated | 2–5 mg | Not completely caffeine-free |
What determines the caffeine in coffee?
Botanical variety
The amount of caffeine varies significantly between species:
- Arabica: approximately 1–1.5% caffeine
- Robusta: approximately 2–2.5%, therefore higher
Brewing Method
The contact time between water and coffee affects caffeine extraction. Longer methods tend to extract a greater amount.
Dose used
The most important factor is the amount of coffee used. For the same method, more grams of coffee result in a higher amount of caffeine.
How much caffeine is in a coffee compared to Red Bull and Monster?
Espresso is often compared with energy drinks to evaluate its “power.” Here are the reference parameters to understand the stimulant load:
- 200 mg of caffeine: Corresponds to approximately 2.5 or 3 espressos.
- Red Bull: A 250 ml can contains about 80 mg of caffeine, the equivalent of a single espresso.
- Monster: One can can contain the caffeine of approximately 2 or 3 coffees.
- Daily limits: Comparison with other beverages helps in understanding the caffeine load, without addressing the topic of daily consumption.
How much caffeine is in a coffee for those suffering from gastritis or reflux?
Caffeine interacts differently with the body depending on health conditions. For those with a sensitive stomach, the choice of raw material is crucial.
The correct choice to avoid heartburn
Those suffering from gastritis or reflux do not necessarily have to give up the pleasure of a cup of coffee, but they must select high-quality coffee.
- What to drink: Tolerability depends more on roasting, quality, and extraction method than on the Arabica or Robusta variety alone.
- The decaf myth: Even if caffeine-free, it can still stimulate acid secretion in very sensitive individuals and worsen gastritis.
- Natural alternatives: If symptoms are acute, it is preferable to opt for alternative beverages that do not irritate the stomach.
Caffeine levels and tolerability
| Beverage | Caffeine (mg) | Tolerability (indicative) |
| Espresso | 60–80 mg | Medium |
| Moka | 100–120 mg | Medium |
| Filter | 80–120 mg | Medium-high |
| Energy drink | ~80 mg | Variable |
| Decaffeinated | 2–5 mg | High |
The role of roasting: how much caffeine is really there?
Many consumers believe that a coffee with a strong, bitter taste (dark roast) is synonymous with a higher energy boost. In reality, to understand how caffeine varies in the cup, we must look at the density of the bean.
Caffeine is a very stable molecule, but the degree of roasting influences its final concentration in the cup:
- Light Roast: The beans retain a higher density. If we measure coffee by volume (for example, a tablespoon), a light roast may contain a slightly higher amount of caffeine.
- Dark Roast: During the process, the bean loses weight and expands. Although the flavor is more intense, the caffeine concentration per bean tends to decrease slightly compared to a light roast.
Why choose a medium roast? For those seeking a more balanced and tolerable coffee, medium roasting represents the ideal compromise.
Unlike mass commercial distribution, we at Esperanto Specialty Coffee select botanical excellence for the most demanding roasters. We provide beans with superior organoleptic profiles that allow roasters to enhance natural sweetness and reduce irritating bitterness. Choosing beans with SCA quality standards means offering your customers a product that respects health, ensuring clean energy and easier digestibility thanks to a defect-free raw material.
Frequently asked questions about caffeine in coffee
How much caffeine does an espresso have? A standard espresso contains an average of between 60 and 80 mg of caffeine, depending on the dose and extraction.
Does a moka pot contain more caffeine than an espresso? Yes, in terms of total quantity per cup. However, espresso has a higher concentration of caffeine per milliliter.
Does filter coffee have more caffeine than espresso? Generally yes, because it is prepared with a larger amount of water and a longer extraction time, increasing the total caffeine in the cup.
Does decaf still contain caffeine? Yes, decaffeinated coffee is not completely caffeine-free. It usually contains between 2 and 5 mg per cup.
Does roasting affect caffeine? Roasting has little effect on the amount of caffeine. Differences depend mainly on density and the measurement method (volume or weight).
Does Robusta have more caffeine than Arabica? Yes, the Robusta variety contains about twice as much caffeine as Arabica, making it naturally more intense.
