To get the best tasting strong coffee, try an espresso, french press, or drip coffee maker. 

Drip coffee usually brews longer than coffee made in a french press or an espresso maker. 

Due to the drip coffee brewing time and the serving size (12 ounces), this usually has the most caffeine.

The three brewing times are approximate as follows;

  • Drip coffee: About 4-6 minutes
  • French press: Around 3-5 minutes
  • Espresso machine: Around 20-30 seconds

Strongest Coffee Beans FAQ’s

frequently asked questions
Q: Are some coffee beans stronger than others?

A: Certain beans have more caffeine (themselves, per mass) than others, so there’s more of it to get extracted into the cup.

Q: Does cold coffee keep you awake?

A: Frozen, or blended coffee drinks often have ice added, which reduces the amount of caffeine overall due to watering the drink down.

But the amount of caffeine could still keep you awake.

Q: How do you grind beans for strong coffee?

A: If you want to make strong coffee, grind your coffee beans right before you’re ready to brew.

If you’re drip brewing, grind the coffee beans to the consistency of beach sand.

A coarse grind like kosher salt is better for a French press.

Q: What happens when coffee sits?

A: When you leave your coffee to sit for too long, the reaction between hydrogen and oxygen will raise the pH level of the coffee, making it taste bitter or “stale”.

Therefore, this is why you should never let your coffee sit in a brewing pot for longer than necessary.

Conclusion: Strongest Coffee Beans

So overall, it is hard to define what “strong” coffee really is.

However, these top 7 brands of the strongest coffee beans focus on the actual caffeine content of their blends, to give you some seriously strong coffee.

Just remember, consume at your own risk, because these super caffeine-charged coffees do not actually taste that different from a regular dark-roast coffee.
