Decaf Espresso Beans - What Are They?



Well, there is no such thing as decaf espresso beans—not in the way you are probably thinking about it.


  • Espresso is a brewing method
  • Decaf is a coffee that had caffeine removed.

Since espresso is a brewing method, you can brew any kind of coffee as espresso, including decaf beans! Which is why people sometimes refer to them as "decaf espresso beans." For the purpose of this post, that's how we’ll refer to them.


Now that you understand the difference, the real question is: What makes a good decaf espresso bean? And why would anyone want to drink one?

Things to Consider When Selecting Decaf Coffee

Decaffeination Process, Roast Level, Bean Varieties


What makes a great decaf espresso? The secret lies in the roast profile of the bean and the decaffeination process.


Unlike traditional methods involving harsh chemicals, Gigawatt’s decaf espresso beans undergo a gentle water-processed decaffeination . This method ensures your coffee maintains bold flavors without any bitter aftertaste.


Let's break down the difference:

Bean Varieties



  • Arabica Beans : Known for their smooth, mellow taste, Arabica beans form the backbone of many decaf espresso blends. They contribute to the rich body and pleasant acidity of your coffee.
  • Robusta Beans : Robusta beans add a touch of boldness and crema, enhancing the overall character of your decaf espresso.

Roast Levels



  • Medium Roast : Maintains the balance between the natural sweetness of the beans and the smoky depth of espresso. Perfect for those who enjoy a well-rounded flavor profile.
  • Dark Roast : Offers intense, caramelized notes that bring out deep flavors, making your decaf brew taste remarkably close to a caffeinated espresso.


Your Perfect Brew: A Deep Dive



1. Grind Size: The Foundation of Flavor

Choosing the right grind size is pivotal. For decaf espresso beans, opt for an ultra-fine grind. This consistency ensures a robust flavor extraction, capturing the essence of the beans without the caffeine kick. Think of it as the canvas on which your coffee masterpiece is painted.



2. Water Temperature: The Science of Precision

The water temperature plays a crucial role in bringing out the nuances of your decaf espresso beans. Keep it between 195°F to 205°F (90°C to 96°C) to ensure the perfect balance between flavor extraction and avoiding bitterness. This precise range allows the coffee grounds to release their flavors without scalding, resulting in a smoother, well-rounded taste.


Also - be sure to use filtered water as opposed to tap water when brewing. Filtered water will deliver a cleaner tasting cup. The quality of water is a very important component to any coffee drink 



3. Brewing Time: Crafting the Quintessential Shot

The brewing time is the heartbeat of your decaf espresso. Aim for a shot that lasts between 25 to 30 seconds. This precise duration allows the water to interact with the coffee grounds, extracting the flavors and aromas that make your espresso exceptional. Too short, and you miss out on the richness; too long, and bitterness creeps in. Find the sweet spot, and you’ve found your perfect brew.


Why Choose Decaf Espresso Beans?



Sometimes you want some coffee with that piece of cheesecake at 10pm…but you also have to get up to go to work in the morning.


Or maybe you already drank copious amounts of coffee during the day and need a little break from the caffeine.


Sometimes a little decaf pick-me-up is what you need.


Say yes to:


  • Peaceful nights without caffeine induced restlessness.

  • The perfect pairing of an after dinner espresso.

  • Feeling good by lowering your caffeine intake and increasing your overall well-being.

The Gigawatt Decaf Difference



Our special Colombian decaf water processed coffee undergoes a pure water caffeine extraction process without the use of chemical solvents.


When we first started Gigawatt, we used to be death before decaf kinds of people . However, we started to get more and more requests to carry decaf espresso beans.


We pride ourselves on the coffee we offer, and would never offer something we wouldn't drink ourselves. After sampling and cupping a ton of decaf espresso beans, we were left impressed with what became our Static Resistor Decaf.


Now we find ourselves pulling shots of espresso with our decaf espresso beans several times per week between 9pm-10pm. 

What Makes Our Decaf Special?


  • Versatile Brewing : Great for drip, cold brew, or espresso.
  • Dark Roast Profile : Air roasted for smooth, bold flavor without bitter, burnt tones.
  • Flavor Notes : Toasted nut, cacao, and a hint of cherry.

You can brew them all different ways,  including drip and cold brew, and it is an excellent choice to use as decaf espresso beans.


Although our decaf has a dark roast profile, we use an air roaster to roast our coffee , so it doesn't get any of those bitter burnt tones that you might expect from a dark roast.


Our decaf has a smooth bold flavor, which is perfect by itself, or also in milk based espresso drinks - such as lattes or cappuccinos. Which is why we now use our decaf espresso beans many nights during the week. 


What does it taste like?


It has  lovely toasted nut and cacao notes  which synchronize to provide a nice body  with just a hint of cherry on the back palate. 


Finally - decaf espresso beans that not only taste great, but will have you coming back for more. 



Final Thoughts: Your Decaf Journey Awaits
