Crystal Malt Guide: How to Brew Beer with Crystal Malts?

Crystal Malts are known as the ‘Swiss Army Knife of Malts’ due to their incredible versatility. In our Crystal Malt guide, we will explore how to start creating excellent beers, ales, stouts, and IPAs with this malt.

There are many types of Crystal Malts ranging from lighter malts which offer lovely sweet finishes right through, to darker Crystal Malts with a bitter and caramel aroma.

In this Crystal Malt Guide, we will look at each type of Crystal Malt, how to brew and store the malts, and what hops to complement it, so you can begin crafting some unique and flavor-busting homebrews.

What is Crystal Malt?

Crystal malt is a variety of malt known as caramel malt; It is a highly popular and versatile malt used in many different beer types. It is a traditional British color malt that can produce a range of different color beers, ales, stouts, and the EBC of Crystal Malts can go from 10 to 320 EBC.

Crystal malts generally have no enzymes, and they are used to flavor beer and enhance the aroma. They have predominantly been used in Britain since the 1920s (but Crystal Malt can trace its roots back to the late 19th century), although they began to be used for bitters after the Second World War.

Types of Crystal Malt

Crystal Malt

Like many different malts (such as British malt, brown malt, and white wheat malt), there are different versions of Crystal Malt that you will come across.

Light Crystal Malt

Light Crystal Malt (10 – 30L) has a honey taste, and because of this, they add an element of sweetness to the beer. When added to the brewing process, they don’t produce a darker color; typically, light Crystal Malts give the beer a crisp and golden finish.

Medium Crystal Malt

Medium Crystal Malts (40L-60L) is the most commonly used version popular with many homebrewers. The medium malt is where the caramel flavor begins to appeal, and this version of Crystal Malt will help darken beer while still ensuring the sweet aroma.

Medium Crystal Malts are used in many stouts, bitters, and even pale ales and add substantial body and head retention. Briess Caramel Malt is a good example of this type of Crystal Malt.

Dark Crystal Malts

At 70-90 L, Dark Crystal Malts will definitely bring a deeper shade to the brews they are added to. You will experience a much more intense caramel flavor with dark Crystal Malts, and hints of bitterness will also begin to creep in. The finish often has a reddish shade, and this type of Crystal Malt is used for body and head retention. You will mainly find this type of Crystal Malt in darker stouts.

Very Dark Crystal Malts

Lastly, we have Very Dark Crystal Malts (100-220 L), and you will find nutty, bitter, and roasted flavors. This is a malt that will add significant dark colors to your homebrews and intense caramel aromas.

If you are using any very dark Crystal Malts (such as Simpsons Crystal Extra Dark), you should add the malt sparingly as it can massively overwhelm the taste of your brew and produce a nasty bitter flavor.

How to Brew Beer with Crystal Malts

Crystal Malt

Crystal malts offer a lot of variety, and they have often been described as the ‘swiss army knife’ of malts, given how versatile they are. So let’s have a look at how you brew with this malt type.

Making Your Own Crystal Malts

Crystal Malts are made from barley grain that has been steeped and germinated. The big difference between Crystal Malts and pale malt varieties is that Crystal Malts are stewed. The stewing part of the process ensures that moisture doesn’t escape and that Crystal Malts have a higher moisture content than many other malt varieties.

The final part of the process is killing. This dries out the malted grain and caramelizes the sugar, which helps to give Crystal Malts their distinct flavor and aroma.

You can grow the barley yourself, although Crystal Malt is widely available to buy. Many online resources will help you grow this homebrewing ingredient, although the most straightforward method is simply purchasing Crystal Malts.

When to add Crystal Malts

The amount of Crystal Malt that you add depends on the type you are putting into your homebrew. For example, very dark Crystal Malt should only be used sparingly as it can ruin the flavor of your beer, ale, or stout by adding a lot of bitterness.

The recipe you are following will tell you how much Crystal Malt to add; however, typically, it is between 5 – 20% for this type of malt, which will add color, aroma, and flavor to your brews.

Storing Crystal Malts

Storing Crystal Malts is simple, and the process shouldn’t be much different than storing any other malt type.

You should keep your Crystal Malt in an airtight container, away from direct sunlight, and in a cool and dry location. Crushed malts should be good for around three months, although they will probably last longer than this. After a more extended period of time, the taste and aroma will begin to be impacted.

Uncrushed malt can be kept in good condition for years as long as they are free from moisture and high temperatures.

Complimentary Malt Varieties

You can use Crystal Malts alongside other malts and hops to create fantastic tasting beers, ales, and stouts.

Base malts such as Pilsner Malt and Vienna Malt are often used in conjunction with Crystal Malt. Wheat Malt is another complimentary malt variety and is often used with a lighter Crystal Malt to create English Pale Ales.

Many homebrewers also use a variety of hops with a small amount of Crystal or Caramel Malts. Citra is a popular choice as its intense citrus aroma with refreshing flavor helps balance out the darker Crystal Malt. You can also use Simcoe Hops, which provides a myriad of flavors, including apricot, pine, citrus, and grapefruit, which also contrasts the dark malt. Lastly, many brewers have found success with Amarillo Hops as it offers a lemony and tropical flavor profile which has worked well in IPAs and beers.

Crystal Malts – Alternatives

If you can’t get your hands on some Crystal Malts or if you want to use an alternative in your homebrew, there are some different malts that will work well.

Munich Malts

Munich Malts

Munich Malts can be used to make darker-colored beers and ales, and it is a malt that is widely used for Oktoberfest. The flavor of Munich Malts is a deep, rich, and grainy taste, while you get a slightly roasted aroma from brews made from the malt too. Munich Malts have low diastatic power, so they aren’t usually suited for a base malt but are excellent for adding flavor and aroma to darker beers and ales.

Vienna Malts

Vienna Malts can be used as a base malt, and this malt also provides great aroma, flavor, and color to beer and ales. Vienna Malt gives off flavors of biscuit with some subtle sweetness. It isn’t as dark as Munich Malt or the darker Crystal Malts, and Vienna is often used in amber or lighter beer.

Briess Goldpils Vienna Malt is a superb example of this classic malt. Less sweet than Pale Ale Malt, it is a rich malty 2-Row base malt that offers complexity and depth with a toasted note at the finish for your classic Vienna, Oktoberfest and Marzen beers.
