Went on holiday to Vietnam and tried the coffee? In that case, you’ll likely have noticed the coffee is quite sweet among other things. Why is that? I did some research and here is what you want to know
Vietnamese coffee tastes sweet because sometimes sugar is added during the roasting process to balance out the bitterness of the Robusta beans. Often a bit of salt is also added in the coffee grounds which reduces the bitterness and brings out the sweet notes a bit more.
There are some other reasons and details why Vietnamese coffee can taste so sweet. Discover more about those reasons below.
Why Does Vietnamese Coffee Taste So Sweet?
Part of the reason why it can taste so sweet is in the beans. Vietnamese coffee is mostly made up of Robusta beans since that’s the majority of beans growing in the country. Robusta beans don’t have a great taste from the plant. They produce a pretty bitter taste. Arabica is much more popular since most people prefer the taste.
Arabica beans actually have more sugars and oils which make the taste of the resulting brew a bit sweeter.
So why does the fact that Vietnamese coffee is mostly Robusta matter? Wouldn’t that make it less sweet? Well, because the taste isn’t that great, especially for lower-quality beans. That’s why Vietnamese coffee roasters tend to add quite a few things during the roasting process.
Common things to add are butter, cacao, vanilla, and sugar. They’re added to round out the taste of Robusta beans and get rid of/cover up some of the less desirable aspects. And if you add those things the taste sticks to the beans of course. Adding some sugar during roasting will create a caramel-like coating on the outside of the bean.
When you grind up those beans you also grind up the caramel coating. That coating ends up in the coffee grounds and will dissolve into your coffee. So in effect, you’re just getting sugar in your black coffee.
That’s also why Vietnamese coffee tends to have quite a lot of chocolate notes. Read more about that in this post.
Often Vietnamese coffee is served with something in it. Not many people drink it hot and black. Here are some of the more popular ones.
Vietnamese coffee is almost always served with ice. In a hot country cold drinks are simply more popular than hot drinks. Vietnamese coffee straight from the Phin is pretty strong. Ice helps to get a cold drink but also to dilute the coffee a bit.
The dilution doesn’t mean the coffee will taste sweeter though. It might actually only cover it up. Cold temperatures actually make you taste the bitterness more and the sweetness less. However, just like ice cream tastes sweeter when it melts on your tongue, the iced coffee warms up on your tongue which can give the illusion of it becoming sweeter. This is going to be a very small effect in the grand scheme of things though.
Often a small pinch of salt is mixed in with the coffee grounds. This is to counteract the bitterness of Robusta. The Sodium in salt interferes with the bitterness of the coffee. At the same time, it can also amplify the sweet taste. If the amount of salt is small enough, you won’t taste any saltiness but the taste of the coffee changes significantly.
Almost all coffee shops in Vietnam that aren’t serving very high-quality coffee for aficionados will add a little pinch of salt. Again, you won’t really taste this but it will reduce the bitterness and amplify the sweetness.
The most obvious thing that’s often added is condensed milk. It’s what makes people like Vietnamese coffee in the first place. Most cups in the country will be served with condensed milk and ice. And while normal milk already has quite a few sugars already, condensed milk has a ton more especially since sugar is usually added.
This will create a very sweet drink that’s delicious but probably not very healthy. So if you see anything that looks like dairy in your Vietnamese coffee, this is why it’s sweet.
It depends where you are but the majority of the time, when you order coffee in Vietnam, they will put something sweet in it. Often condensed milk, as mentioned above.
But even if you order black coffee there is a good chance you get sugar in there. The vast majority of the time you’ll get sugar in your coffee if you don’t specify you DON’T want any. It’s just standard. So it’s possible that even if you didn’t ask for sugar or milk, you still got sugar. That’ll make it sweet.
If you’re lucky, you’ll get the sugar separately but especially at the cheaper coffee shops, it’ll be mixed in before it’s served.
Soy and corn
Sometimes real coffee is replaced by something that looks like coffee but isn’t. Soy and corn can be roasted and chemicals can be added to make it seem like coffee while it isn’t. People do this simply because it’s a lot cheaper and you make more money per cup if you serve this.
You won’t find this in higher quality coffee shops but at the cheaper roadside coffee places there is a decent chance you’ll get a cup that’s not coffee or blended with real coffee. To make this taste good, they’ll use a lot of different things to make it taste decent. This is pretty much meant to be served with condensed milk so it might not taste too great without it.
There are quite a few reasons why Vietnamese coffee can taste very sweet. Often it’s served with things that make it taste sweet like condensed milk and sugar. However, there are also things in the roasting and brewing process that make it taste sweeter once it’s in your cup. The use of additions during the roasting process and a bit of salt during brewing will make it taste Vietnamese coffee a bit sweeter.
And there is always the chance that there is just sugar added to your cup if your order wasn’t specific enough.
Why is Vietnamese coffee so strong? Vietnamese coffee is mostly made from Robusta beans. Robusta beans have a strong earthy taste and contain a lot of caffeine. The brewing method in a traditional Phin means a pretty long brew time of around 5 minutes which means the extraction is pretty high.
Why does Vietnamese coffee taste like chocolate? Robusta coffee has more earthy and bitter notes than Arabica beans but they don’t taste like chocolate. That taste comes from cacao that’s added in the brewing process to round out the taste of Robusta beans.
