What is Herbal Beer?

Herbal beer uses an herbal mixture as the primary bittering and flavoring agent instead of hops. These botanical brews rely on everything from yarrow and mugwort to chamomile and spruce tips to create their unique character. It’s beer made the way people did it for thousands of years before hops became the standard.

The most famous type of herbal beer is called gruit (pronounced “groo-it”), which is a herb mixture used for bittering and flavouring beer, popular before the extensive use of hops. When you compare herbal beer to traditional craft beer, you’re looking at two completely different flavor experiences. Regular beer gives you that familiar hoppy bitterness, while herbal beer can taste earthy, floral, spicy, or piney, depending on what herbs are used.

Modern herbal ales and botanical beers aren’t just historical curiosities. Craft brewers who use gruit on its own or alongside hops for a more complex and often unpredictable flavor profile are bringing these ancient recipes back to life. The real appeal lies in their unpredictability – while hopped beers deliver consistent bitterness, herbal beers can surprise you with sweet, spicy, floral, or earthy notes depending on the botanical blend.

What makes herbal beer special is that every batch can taste different. The herbs you choose, when you add them, and how much you use all dramatically affect the final product. It’s a style that rewards experimentation and gives homebrewers tons of creative freedom.

The History of Herbal Beer

Before hops became the go-to beer ingredient, people were already perfecting herbal brewing thousands of years ago. The history of herbal beers, ales, meads, and wines goes back to at least 10,000 BC, making this one of humanity’s oldest culinary traditions. Medieval Europe particularly embraced gruit brewing, where specific gruit recipes were often guarded secrets.

The real turning point came during the Middle Ages when politics got mixed up with beer. During the 11th century, the Holy Roman Emperor Henry IV awarded monopoly privileges of the production and sale of gruit (Grutgerechtigkeit ‘grut licence’) to different local authorities. This wasn’t just about flavor – it was about control and taxation. If you wanted to brew beer in certain areas, you had to buy the official gruit blend, and the authorities controlled who could make it.

The decline of herbal beer happened gradually as hops spread across Europe between the 11th and 16th centuries. The main factor for the replacement of spices by hops is that hops were cheaper and were better at rendering the beer more stable. Hops were simply more practical – they grew easily, preserved beer effectively, and provided consistent results. The German Purity Law (Reinheitsgebot) pretty much sealed the deal by restricting beer ingredients to just water, hops, malt, and yeast.

But herbal beer never completely disappeared. Although largely replaced by hops in the 14th and 15th centuries, gruit-flavored beer was locally produced in Westphalia until at least the 17th century. Today, we’re seeing a revival as craft brewers rediscover these ancient techniques, with International Gruit Day celebrated every February 1st to honor this brewing tradition.

Benefits of Brewing with Herbs

Brewing with herbs opens up flavor possibilities that hops simply can’t match. Here are the key advantages that make herbal brewing so appealing:

• Flavor complexity – While hops provide consistent bitterness and familiar citrusy or piney notes, herbs can deliver everything from floral sweetness to earthy astringency in the same glass. Combining these and other herbs creates a complex and often unpredictable flavor profile, ranging from herbal and earthy to floral and spicy.
• Natural preservation – Many herbs contain essential oils that act as natural preservatives, just like hops do. Much like hops, its bittering, antibacterial, antiseptic, and antimicrobial actions could balance an ale and protect it from infection. This means your herbal beer won’t just taste different – it’ll stay fresh longer without relying on modern preservatives.
• Health appeal – There’s also the health appeal factor that’s driving renewed interest in herbal brewing. These days, we “drink to our health,” but there was a time when that toast had a bit more meaning, as the brew itself was intended to be medicinal. While we’re not making medical claims here, many traditional brewing herbs have been used for wellness purposes for thousands of years.
• Creative freedom – From a practical standpoint, brewing with herbs gives you creative freedom that’s impossible with hops alone. You can craft seasonal beers using locally foraged ingredients, create signature blends that reflect your local area, or recreate historical recipes that tell stories. Some brewers even combine herbal brewing with wildcrafting, sourcing their botanicals directly from nature – though always sustainably and legally, of course.
• Cost effectiveness – Many herbs are cheaper and easier to find than specialty hops, especially if you grow them yourself. Plus, you’re not limited to what hop varieties are available – the herb world is massive and mostly unexplored by modern brewers.

Popular Herbs Used in Beer

The world of brewing herbs is huge, with each botanical bringing its character to your beer. Yarrow stands out as one of the most versatile options, earning the nickname “earth hop” in Scandinavia. Yarrow is one of the most versatile brewing herbs, useful for bittering, flavoring, and as a preservative. It delivers a sage-like, mildly spicy character with subtle citrus and woody notes.

Mugwort is another brewing powerhouse that’s been used for centuries. Artemisia vulgaris is one of my favorite hop substitutes. A preservative as well as a flavoring and bittering agent. It brings an earthy, grassy quality to beer, with some varieties even called “dreamweed” for their unique properties. If you want to homebrew with mugwort, you can use eight grams of the herb per gallon of water.

Chamomile might seem like an unlikely beer ingredient, but it’s fantastic for balancing sweetness and adding floral complexity. Chamomile adds a balancing flavor to homebrewed beer. It dulls the excessive sweetness of the beer, making it one of the most effective hop replacements. Use between one to three ounces per gallon, as it can quickly overwhelm delicate flavor profiles.

Spruce tips deserve special mention for anyone wanting to capture that piney, resinous character. They are a popular beer flavor and hop replacement for those seeking an earthy flavor. Spruce also possesses a powerful aroma that permeates the beer. They’re particularly popular in Nordic brewing traditions and can add serious complexity to dark beers.

Other excellent choices include juniper berries for forest-like notes, heather for floral sweetness, and sweet gale – one of the traditional gruit herbs. Other adjunct herbs include marsh rosemary, laurel berries, laserwort, ginger, caraway seed, aniseed, nutmeg, cinnamon, mint, and resin. The key is understanding that myrcene and humulene – aromatic compounds that give herbs their distinctive scents – will translate directly into your finished beer.

Brewing Equipment You’ll Need

Getting into herbal brewing doesn’t require completely new equipment, but some specific considerations will make your brewing much easier. Your basic homebrew setup remains the foundation, with a few herbal-specific additions:

• Fermenter – Plastic buckets (budget-friendly), glass carboys (watch fermentation), or stainless steel conical fermenters (professional control)
• Airlock – Allows carbon dioxide to escape while preventing contaminants from entering your fermenter
• Wort chiller – Essential for preserving delicate herbal flavors and aromatic compounds through quick cooling
• Fine-mesh bags – For containing loose herbs during the boil to prevent plant matter in finished beer
• Extra sanitized containers – For making herbal teas and handling botanical additions
• Multiple airlocks – Herbal fermentations can be more vigorous, so keep spares handy
• Temperature control – Fermentation belts, swamp coolers, or dedicated chambers for consistent temperatures

How to Brew Herbal Beer at Home

1. Start your mash – Begin with your mash just like any all-grain brew. Heat water and target a mash temperature of 154°F. Slowly add crushed grain to hot water, stirring well to prevent clumping or dough balls. Rest mash for 60 minutes. While your grains are converting starches to sugars, this is the perfect time to prepare your herbal additions and organize them by when they’ll go into the boil.
2. Prepare for the boil – The boil is where herbal brewing gets interesting. Unlike hops, which follow predictable timing schedules, herbs require more careful attention. I used mugwort in the boil to impart an earthy bitterness, and yarrow at flameout to add a more complex bitterness and a spicy, sage-like aromatic note. Bittering herbs typically go in early in the boil, while delicate aromatics should be added late or even during primary fermentation.
3. Monitor the steep phase – During the steep phase, you’re extracting essential oils and flavor compounds that’ll define your beer’s character. The process starts with brewing a herbal tea using the herbs and water, which is then sweetened to create what’s known as the wort. Monitor temperatures carefully – too hot and you’ll extract harsh tannins that make your beer taste astringent; too cool and you won’t get full extraction of the good flavors.
4. Handle primary fermentation – Primary fermentation with herbal beers can be more active than you’d expect. Otherwise, there is a high risk that other microorganisms will outcompete the pitched yeast, resulting in undesirable qualities or off flavors in the beer. Keep your sanitation game tight, maintain proper fermentation temperatures, and be patient – herbal beers often need extra time to develop their full complexity. Don’t rush the process.

Flavor Profiles and Pairings

Herbal beers offer a huge range of flavors that can completely change what you think beer should taste like. The beauty lies in their unpredictability and complexity. While hops deliver a standard bitterness, gruit can introduce sweet, bitter, spicy, or floral notes depending on the herbs used. You might encounter astringency from tannin-rich herbs, floral sweetness from chamomile or elderflower, earthy depth from mugwort, or piney resin from spruce tips.

The aroma is completely different, too. Where hopped beers give you familiar citrus, pine, and floral notes, herbal beers can smell like a fresh herb garden. Generally, the leaves and flowers have a mildly herbal spicy aroma (slightly sage-like), especially when crushed. Other characteristics sometimes associated include citrus, woody/earthy, peppery, pine, and mint.

When it comes to food pairings, herbal beers open up possibilities that regular beer simply can’t match. Because gruit has a more herbal flavor, it tends to pair well with roasted meats like venison, especially if those meats are cooked with complementary aromatic herbs like rosemary and thyme. The earthy, complex flavors complement wild game beautifully.

Cheese pairings get exciting with herbal beers. Gruit beers also go nicely with washed-rind cheeses like an Italian taleggio or something similar. The funky, aromatic qualities of these cheeses work well with the botanical complexity of herbal beers. Strong, aged cheeses can stand up to the intensity of yarrow or mugwort, while delicate herbs like chamomile pair beautifully with fresh goat cheese.

The best advice for pairing food with gruit beer is to check the label, since there’s a wide variety of herbs used in gruits, no two are ever quite the same. This variability is what makes herbal beer so exciting – each batch is a unique flavor experience waiting to be discovered.

Common Mistakes to Avoid

• Using too much herb – The biggest trap new herbal brewers fall into is using way too much of their chosen herbs. The strong aroma can be overwhelming if you brew too much mugwort, so test a few batches to see what suits your pallet. Start conservative – you can always add more herbs next time, but you can’t remove them once they’re in the boil. What tastes like a light herbal tea might create an overpowering beer.
• Poor timing – Timing mistakes can ruin an otherwise perfect herbal beer. Chamomile can become bitter in boiling and lose its precious citrusy, floral, and honey-like notes. Understanding each herb’s extraction characteristics is crucial – some need long boils to release their bittering compounds, while others should only be added at flameout or during fermentation to preserve delicate aromatics.
• Contamination risks – Contamination risks increase with herbal brewing because you’re introducing more variables into your process. My first gruit brew included mugwort, St. John’s wort, and horehound, and was, well… undrinkable. Fiendishly bitter, even for me, while at the same time tasting thin. This highlights another common mistake – not understanding how different herbs interact with each other and can create harsh, unpleasant flavors.
• Overbittering – Overbittering is perhaps the most common off-flavor in herbal beers. Unlike hops, which provide predictable bitterness levels, herbs can contribute harsh, astringent qualities that make beer unpleasant to drink. When creating your herbal brew, the key is to make a blend that tastes good as an herbal tea. This will guide you in making a beer that is not only drinkable but enjoyable.
• Neglecting sanitation – Don’t neglect proper sanitation just because you’re working with “natural” ingredients. Wild herbs can carry unwanted microorganisms, and the complex sugars in some botanicals can create environments where spoilage bacteria thrive. Always sanitize everything that touches your wort after the boil, and consider sourcing your herbs from reputable suppliers rather than wildcrafting until you’ve mastered the basics.
