Which Type of Coffee Keeps You Awake?

Drinking caffeine in quality coffee if you want to keep yourself awake has become a morning habit for me and probably for many coffee lovers. With my extensive brewed coffee experience, customers often ask me: “What coffee keeps me awake?” While all cup of coffee contains caffeine, some types pack more of a stimulant punch than others. 

Whether it’s a robust Vietnamese Robusta that keeps for awake all night, or a light, aromatic Ethiopian Arabica that keeps you alert and awake without the jitters, understanding how different café powder origins and types influence the Caffeine keeps you awake is crucial. The key is knowing how factors like bean variety, origin, roasting, and brewing affect levels of caffeine. 

But is it solely the delicious coffee that is capable of sustaining your alertness, or could an energy drink contest that title? Read on as I break down the foods and how to drink coffees at home that deliver the most jitter-free jolt to stay awake and alert.

Caffeine Content by Coffee Type

The two main commercially grown prevalent coffee bean types – Arabica and Robusta – naturally contain different amounts of caffeine:

  • Arabica – 1.2% on average. Arabica beans make up 59% of world production.
  • Robusta – 2.2% on average. Robusta comprises 41% of global.

Due to its nearly double content, Robusta tastes more bitter and harsh. But the higher offers more stimulation, making Robusta a common component of energizing espresso blends. For those interested in diving deeper into preparing the perfect espresso at home, these espresso grinding tips might prove handy.

Some other café species like Liberica and Excelsa contain even higher caffeine concentrations, which type is best to keep you awake but they are less commercially prevalent.

Caffeine by Origin

The country coffee originates from also impacts caffeine-level. Here are some average caffeine concentrations:

  • India – 1.2% (mostly Arabicas grown in shade)
  • Ethiopia – 1.2% (birthplace of Arabica)
  • Colombia – 1.2% (100% premium Arabicas)
  • Brazil – 1.1% (major Arabica producer)
  • Vietnam – 2.6% (major Robusta producer)
  • Indonesia – 1.2% (both Arabica and Robusta grown)
Caffeine by Origin

As these numbers show, Robusta-growing countries like Vietnam tend to produce strong coffee, creating stronger coffee that will keep the mind alert longer. However individual coffee bean use of caffeine differs, so the origin is not an absolute determinant.

Caffeine Content by Processing and Roasting

Processing and roasting coffee every time also impacts caffeine-level:

  • Processing – The washed processing method used for most Arabica beans removes more caffeine than natural or honey processing. This can be reduced by up to 10%.
  • Roast Level – Darker roasts actually contain slightly less caffeine than regular coffee and light roasts, since roasting breaks down some of the caffeine molecules over time. But the difference is marginal.

So while processing and roasting influence caffeine slightly, their effects pale in comparison to the bean varietal.

Caffeine Delivery by Brew Method

While brewing doesn’t alter caffeine amount per se, it does control how efficiently caffeine is extracted from grounds into your cup:

Brew MethodCaffeine Extraction
Drip coffee18-22%
French press80-85%
Cold brewTime-dependent
Caffeine Delivery by Brew Method

Methods that expose all the grounds to hot water for longer (French press, espresso) extract virtually all the caffeine work from the beans to produce the strongest coffee. Cold brew is less efficient, so requires longer brewing over 12-24 hours. make a cup of drip coffee methods yield moderate extraction.

So using an intense method like espresso on Robusta beans would provide the biggest kick!

Choosing Beans to Maximize Alertness

Based on all these factors, here are some caffeinated coffee types I recommend for you when enjoying a flavorful cup of coffee to stay alert:

  • Robusta Espresso Blends – The natural caffeine punch of Robusta, boosted by espresso coffee’s high extraction, delivers an unbeatable jolt.
  • Vietnamese or Indonesian Robusta – Single cups of coffee origins like Vietnamese Robusta provide full caffeine flavor without the bitterness of cheaper commodity Robusta.
Choosing Beans to Maximize Alertness
  • Percolated Light Roast Arabicas – Percolation competes with espresso for thorough extraction. Combined with 100% Arabica beans, this provides smooth stimulation.
  • Cold Brew Concentrate – While cold brewing requires long steep times, concentrating the liquid produces a smooth cold brew coffee caffeine boost to stay awake.
  • Indian or Ethiopian Arabicas – Careful processing helps these Arabicas retain more caffeine for an eye-opening cup.


  • Arabica beans contain just over half of the caffeine amounts of Robusta beans (1.2% vs. 2.2% on average).
  • Coffee from Robusta-producing countries like Vietnam has higher caffeine amounts.
  • Processing and roasting influence caffeine levels slightly, but not majorly.
  • The brewing method significantly impacts how much caffeine is extracted from the grounds. Espresso and French press extract the most.
  • Choosing beans with naturally higher caffeine amounts and brewing using high-extraction methods provides the biggest stimulation.

No matter your brew, caffeine amounts are one of its allures. With knowledge of caffeine differences between bean types and making cups of brewed coffee methods, you can choose your perfect cup to power your day!
