Finding out how to sweeten coffee without sugar can be tricky. Lots of sites recommend stevia or monk fruit. Adding these to your coffee will make it taste sweeter, but it's still an artificial enhancement of coffee's natural sweetness. Adding sugar isn't definitively bad, but drinking naturally sweet coffee has a more complex and rewarding taste, not to mention the health benefits for your heart and gut. From brewing method to beans, I spoke with nutritionists and baristas to find out their top tips for achieving a sweeter sip.

Switching out a lump of sugar or pump of syrup will do wonders for your coffee cup. I speak from personal experience. The first coffee I ever tried was mostly heavy cream and sugar. Whilst it tasted incredible, it was certainly not good for my health. After training as a barista, I learnt that using a quality coffee grinder, quick brewing method, and adding a splash of milk can naturally sweeten a cup of coffee. You don't need anything else for a full-bodied cup.

Rest assured, there are plenty of methods, tips, and surprising tricks that you can try in place of artificial sweeteners. Rather than improbable, the results of these sweetening hacks have been really impressive. It all starts with the beans.

The beans

Every coffee begins with beans. Depending on where your beans have been grown, they’ll have different flavor profiles. The general consensus amongst baristas is that Arabica beans have a sweeter and more mild taste when compared to Robusta beans. 

Genevieve Kappler, Director of Coffee at Roasting Plant, says that the perfect cup of coffee depends on 'all-important, fresh roasted coffee beans. She says that her favorite beans are 'Uganda Rwenzori or any deeply chocolaty, caramelly, spicy coffee beans, which have a fuller body.' Genevieve recommends preparing them in a French press for 'a more deep, rich, and heavier mouthfeel.

I'd also recommend Liberica beans, like these from Amazon, because they  are the sweetest tasting. However, they're more of a novelty than a plausible choice for regular drinking due to their scarcity. Arabica beans are the next sweetest, with the sugars best preserved at a medium roast. Her general rule is ‘the higher the altitude of the coffee bean farm, the sweeter the beans’. This means that other popular options for sweet beans are places like Colombia, Kenya, Guatemala, Panama and Ethiopia. Just make sure to buy fairtrade and organic where possible too. I’d always recommend Union or Origin coffee.

It’s paramount that you buy your beans whole if you want a sweeter coffee. Grinding whole beans yourself means that you control the grind size and how the beans' oxygen exposure. When grounds oxidize, they taste bitter and stale. If you can grind them just before use, they’ll taste much fresher and sweeter. Peter Conroy, health and coffee expert, went into the details of grinding with me. He said ‘grind size affects the extraction rate and balance of flavors during brewing. Finer sizes allow for faster sugar extraction without risking over-extraction and bitterness.’

Fine grinds don’t suit every method, so you’ll want to match a fine grind with an espresso machine or pour over. I’ll go into methods in more detail, but if you don’t own a grinder at home, here are the best ones on the market.

The method

Time and time again, baristas emphasised ‘blooming’. This is where you dampen your ground beans for 30 seconds to release the CO2 from your grounds. CO2 makes your coffee taste acidic, so you'll want to 'bloom' your grounds for a sweeter flavor. Once you’ve brewed your coffee, remove the crema. This is the hazelnut foam you'll see on top of any good espresso. Removing it from your drink is a divisive topic in the coffee community; the crema balances the flavors of your cup of joe perfectly. However, in professional coffee tasting competitions, experts will remove the crema, because it has a really strong ashy and bitter taste which can overpower the rest of the drink.

The way you brew coffee will give vastly different results too. As mentioned, a fine grind and fast extraction is more likely to yield a sweeter brew. Therefore, the methods which are best suited to sweeter cups of coffee are fast, high-pressure ones. An espresso machine is designed with this task in mind. Pulling an espresso is the fastest way to have a sweeter coffee. However, if you don’t want a big machine, a pour over or moka pot will yield similarly sweet and delicate results. Cold brew has a different flavor profile from normal coffee, because it is extracted under different conditions. It's much sweeter, so you can follow our guide on how to make cold brew if you'd like to mix up your coffee style.

I would avoid a French press, for example, which requires a coarse grind and longer brewing time, resulting in a more acidic brew. Below are tried-and-tested coffee makers that will give you a sweeter cup of joe.

It’s not only the brew that will make your coffee sweet, it’s also the type of coffee that you drink. Adding milk to your coffee provides sweetness, whether it’s plant-based or dairy. Therefore, if you have a pod or automatic coffee machine, you’ll be able to select some sweeter coffee types, such as a cappuccino, latte, or even a mocha. These are the machines that we would recommend you try:

Nutritionist tips

Whilst the baristas were full of technical tips, I know that you might want some more tangible tips. Nutritionists and health experts were full of innovative ways to naturally sweeten your coffee. One of the more common recommendations was replacing sugar with stevia or monk fruit. These don’t have the controversial aspartames in like other sweeteners, but also aren't the same as refined sugar. Registered dietician, Trista Best, explained that ‘monk fruit has been used for medicinal purposes for centuries and gets its sweetness from the antioxidants that it contains, rather than the natural fruit sugars glucose and fructose. These work in the body to counteract free radical damage that leads to disease and illness. This means that monk fruit sweetener can help to prevent cancer, bringing balance to blood glucose, and it is naturally anti-inflammatory’. This is a great alternative if you’d really struggle to give up adding a spoonful of sugar. However, it doesn’t change your cravings for sugar, so might not help you in the long run.

Deniz Efe, founder of Fitness Equipped, with a background in molecular and medical biotechnology, has some natural tips for adding sweetness. ‘One way to sweeten coffee naturally is with cinnamon, which adds a subtle sweetness and an exotic flavor’. He recommends sprinkling it into your coffee along with nutmeg, cardamom, and ginger. He also occasionally adds almond or vanilla extract to his coffee. He says that ‘both are excellent options for providing a slightly sweet flavor to your coffee without overwhelming it. You could also try adding coconut milk or almond milk as an alternative with a hint of sweetness that doesn’t sacrifice the creamy texture’.

What is the healthiest way to sweeten your coffee?

We’ve established that refined sugar isn’t great for you when consumed in large quantities. Sweetening your coffee without it, therefore, makes it healthier. There’s no number one healthiest way to do it, so experiment with grind size, brewing methods, and then culinary add-ins, from vanilla to cinnamon.

What can you use in coffee instead of sugar?

There’s endless possibilities of flavors that will naturally sweeten your coffee. I had lots of recommendations for almond and vanilla extract as well as cinnamon and other sweet spices. If you’re adventurous enough, try salt. The minerals balance the coffee oils and enhance the flavors, making floral and fruity notes stand out more. 

What’s the sweetest brewing method for coffee?

I’d recommend using an espresso machine because you’re coffee is brewed quickly and finely ground. This minimises how much your coffee will oxidise and so will make your coffee taste naturally sweeter. Some machines, like the Breville Barista Pro, can pre-infuse your grounds with water, releasing even more CO2, so that your cup tastes even sweeter. 

What’s the best grind size for sweet coffee?

Using a fine grind will give you a sweeter taste because your water will extract more coffee oils in a shorter space of time, so it will oxidise slower. Make sure not to over or under brew your cup, because that will counter balance the flavors of your coffee.

What’s the sweetest type of coffee?

Aside from a mocha or affogato, which has sugar added, a cappuccino or latte will be sweeter. Any coffee that you add milk to will be naturally sweetened by the sugars in the milk. Experts often recommend lactose free milk or dairy free milk because the molecule chains are shorter, so they taste sweeter, but I would recommend trying out a few different ones before you settle. 

Is it bad to add stevia to my coffee?

If you want to dramatically sweeten your coffee without adding sugar, stevia is a great option. Your body doesn’t process it in the same way that it does sugar, so you’ll taste sweetness without a spike in blood sugar. 

Can I add sugar to my coffee?

If you want to, add sugar. Experts recommend that you limit how much sugar you add, since it can increase glucose levels in your blood. Keep a careful eye on your body, but there’s nothing wrong with adding some carmel or vanilla syrup to your coffee on occasion. 

Why does my coffee taste bitter?

If you want to sweeten your coffee, it might be that you're brewing it in a way that is drawing out too much bitterness. Under or over brewing can result in bitter coffee, because the oils aren't balanced. If you add water that is too hot, it could be burning your coffee grounds, making them bitter too. It could also be that you're not grinding your coffee in a way that matches your brewing type: a fine grind suits espresso, whereas a coarse grind suits a French press.

What does coffee taste like without sugar?

Unless you use sugar-free syrups or artificial sweeteners, it’s unlikely that your latte will taste like you’ve added a lump of sugar or pump of syrup. However, once you strip back the artificial sweetness, you’ll taste citrus, nutty, berry, or floral notes in your cup of joe. This will probably encourage you to try different types of coffee beans to enhance their different notes in your brew.

Our verdict

There’s a lot that you can do to make a sweeter cup of joe. Plenty of these methods are natural and healthier than my original blend of heavy cream and sugar sachets. I think you’ll find that you get a lot more from your cup when you start letting it speak for itself. If you fancy something really wild, try adding salt. It sounds counter-intuitive, but you’ll never go back. I promise.

Remember to use filtered water and to experiment with the ratio of coffee and water that you use. These are coffee basics, but, as you’ve seen, when you tweak the basics, it can make a lot of difference.
