What Malts Will Add Sweetness to Homebrew Beer?
Experimenting with different malts can help you achieve a range of unique tastes. There are various malts that will bring sweetness to your brew, as well as additional interesting flavors.
Caramel and crystal malts will add sweetness to your brew with a rich caramel flavor. You can use them in your malt for 3% to 15%. Bigger quantities will give deeper colors and additional tastes, such as toffee, nut, prune, or raisin.
When choosing the malt to work with, you should keep in mind the end goal for the beer flavor. In this article, I’ll discuss the malts that can make your beer sweeter, their unique traits and undertones, and how to choose the one that’ll perfectly fit your beer style.
Caramel and Crystal Malts Explained
Caramel and crystal malts are united by their sweetness which makes them stand out among other malt types. You can use them in your malt up to 15%. The more you use, the more sweet undertones your beer will get, but avoid exceeding the specified limit.
Before we dive into details, it’s important to get a general idea of what caramel and crystal malts are.
I’ll start by saying that they are almost the same thing. Sometimes, these terms actually mean the same thing and are used interchangeably. That’s because the two categories do somewhat overlap, but there’s still a difference between them.
To avoid confusion, let’s clear this up right away. In what ways are these two malt types similar, and what are their key differences?
Crystal malts are those that undergo the process of roasting. Caramel malts include both roasted and kilned malts. In short, caramel malts are a broader category that includes crystal malts.
Both roasting and kilning contribute to the sweet flavors of caramel and crystal malts and produce unique traits in their own slightly different ways.
Roasted vs Kilned Malts
Generally, you’ll get more sweetness from roasted malts. They bring intense caramel flavor and often have undertones of dried fruit, such as raisin and prune. Kilned malts, on the other hand, give smoother sweetness and darker colors and are typically malty.
The method used to dry the malts determines the slightly different flavor qualities. Let’s take a closer look at each one to see where the sweetness and different undertones come from.
Roasting in its nature is similar to mashing, where the grains are heated to extract sugars. If you want to learn more about mashing, here’s a video from HomeBrewAdvice that explains it in under three minutes:
However, water is not added to the roaster, so only the liquid contained inside the grains takes part in the process. As a result, sugars get trapped inside the grains.
Further heat treatment leads to caramelization which brings the sweet caramel flavor to the finished malt. Depending on the timing and heating temperatures, malt can be more or less sweet and give different colors to your beer.
Kilning, on the other hand, produces a unique result, where the level of caramelization differs within one malt.
Unlike roasters, kilns can’t provide the same conditions for all the grains that are being dried. Inner layers get more humidity and heat, which allows sugars to do their magic, while the top layers remain dry and can’t support temperatures sufficient for caramelization.
Kilned malts end up mixing dry malty grains with sweet ones, which results in less pronounced sweetness in beer and malty, sometimes bready undertones, reminding you of a toast crust.

Choosing Your Malt Style
Both styles can produce excellent beers and are loved for their individuality. So how do you pick the one that’s best for you?
If you want to add a candy-like sweetness to your beer with refreshing fruit undertones, go for a roasted malt. It’s smoothly sweet and can produce sufficiently complex flavors while staying true to your main purpose: bringing in the sugar.
If you’re ready to embrace your beer’s maltiness and bready nature, kilned malts should be your choice. The sweetness will be less pronounced and complemented by pleasant undertones of nut and bread crust.
If you’re looking for ways to sweeten the beer because you struggle with bitterness in your homebrew, this article has some useful tips.
While choosing the malt, pay attention to the temperatures at which it was dried. Some malts work best with dark beers, whereas others can produce wonderful golden color and refresh your pilsner or lager (if you don’t know the difference, I explain it in detail here).

Now that you know what caramel and crystal malts are, let’s take a closer look at some specific examples.
A wide range of malts fall into these two categories, and while they all add a pleasant sweetness to your homebrew, you’ll be amazed at how much the end flavor varies.
