Barley Coffee

What is barley coffee?

Barley coffee starts with barley grain that has been roasted to develop its brown colour and roasted aroma. Depending on the product, the grain is sold whole, ground for brewing, or as a soluble preparation that can be stirred straight into hot water or milk.

“Coffee” describes its role as a replacement drink, not its botanical identity. A packet containing only roasted barley contains no coffee beans. It belongs among the coffee substitutes, but deserves to be understood as a drink in its own right rather than judged solely on how convincingly it imitates espresso.

The preparation instructions matter as much as the name. Ground barley and instant barley can look superficially similar in a packet, yet they behave differently in the cup: ground grain leaves material to filter out, whereas a soluble product is intended to dissolve.

Italian caffè d’orzo, mugicha and boricha

In Italy, caffè d’orzo is the familiar name for barley coffee. Manufacturers supply roasted, ground barley for moka preparation, alongside espresso-compatible products and instant versions.

An orziera is equipment designed for preparing barley drinks. Bialetti, for example, describes its barley brewer as using traditional moka technology with an additional separator to retain barley residue. Espresso preparation is a separate option, requiring a suitable barley product and compatible equipment.

Japanese mugicha and Korean boricha belong to the roasted-barley tea tradition. Here, the emphasis is on an infusion made from roasted grain, including products packed into large brewing bags, rather than necessarily a concentrated coffee-style serving.

These categories overlap in their ingredient, but they are not interchangeable brewing instructions.

What does barley coffee taste like?

Expect toasted cereal, malt and a rounded roasted aroma rather than an exact copy of coffee. Producers describe barley drinks using terms such as roasted grain and malty character. The useful expectation is a drink that recalls the browned crust of bread more readily than the bright fruit of some coffees.

Preparation changes that impression. A concentrated serving puts the roasted character at the front; a longer infusion makes a different drinking experience. Milk is an established serving option, including cappuccino-style preparations made with suitable barley products.

Taste the drink plain before adding anything. That gives you a clearer basis for deciding whether you want more concentration, a longer serving or milk, rather than immediately covering an unfamiliar flavour with sweetness.

Why roasting makes barley smell coffee-like

Roasting is not simply a way of darkening the grain. Heat drives chemical changes, including the Maillard reaction, a group of reactions involving sugars and amino compounds that helps create browned-food aromas.

Research on roasted barley has identified compounds associated with roasted and caramel-like characteristics. This helps explain the resemblance to coffee, without making the two ingredients chemically or sensorially identical.

The grain and its processing also matter. Laboratory research has found that changing barley’s composition and treatment changes the aroma compounds formed during roasting. “Barley coffee” therefore describes a category, not one fixed flavour.

Gluten: who should avoid barley coffee?

Ordinary barley coffee is not gluten free and should not be offered to someone with coeliac disease. Coeliac UK lists barley among the grains to avoid, and NHS guidance includes foods and drinks made from gluten-containing grains.

Barley’s relevant gluten proteins are called hordeins. Immunological research has examined their ability to provoke responses in people with coeliac disease. The concern is the barley itself, not merely accidental contact with wheat.

Brewing does not provide a reliable way round this. The National Celiac Association specifically identifies barley-seed tea, including Korean boricha, as not gluten free. A clear-looking infusion is not evidence that a drink is safe, and straining out the visible grain is not a validated gluten-removal process.

For someone avoiding gluten, choose an appropriate product with suitable gluten-free labelling instead. Our guide to caffeine-free hot drinks provides a broader starting point, but each product still needs checking.

Reading the label in the UK

Look for barley, not just the word “gluten”. Food Standards Agency guidance for England, Wales and Northern Ireland requires gluten-containing cereals to be identified by their specific cereal name and emphasised in ingredients lists where required. Food Standards Scotland gives corresponding guidance for Scotland.

Also check added ingredients and precautionary allergen statements. A caffeine-free claim says nothing about gluten suitability, and “coffee substitute” is not an allergen guarantee.

If you have a diagnosed barley allergy or a prescribed gluten-free diet, follow your clinician’s or dietitian’s advice rather than trying a small serving to judge your reaction.

How to make barley coffee

Start by reading the packet and checking that the product matches your brewing method. There is no single recipe that sensibly covers soluble powder, ground barley, espresso pods and barley tea bags.

For a first attempt, use an established food product sold for making drinks. This removes the extra uncertainty of selecting and roasting grain yourself.

A simple cafetière method

Caffè Pazzini publishes a press-filter method using approximately 4 g of ground roasted barley per serving, water at approximately 80°C, and 5 to 10 minutes of infusion. The method below adopts those instructions, with 200 ml chosen as an editorial serving size because the manufacturer does not specify the water volume.

You need: ground roasted barley suitable for infusion, scales, a measuring jug, thermometer and cafetière.

1. Check the product. Use ground roasted barley, not soluble powder.
2. Measure the ingredients. Put 4 g of barley into the cafetière and measure 200 ml of drinking water.
3. Add the water at about 80°C. Stir to wet the grounds.
4. Infuse for 5 minutes initially. The manufacturer’s stated range extends to 10 minutes, so record the time that gives your preferred concentration.
5. Separate the drink from the grounds. Lower the plunger gently and pour into your cup.
6. Taste before adjusting. On the next brew, change the dose or infusion time separately so you can identify which adjustment helped.

This is a manufacturer-based starting method, not a universal barley standard or a first-hand tested recipe. Follow your own product’s directions if they differ.

Soluble barley

Soluble barley needs dissolving, not extraction. Crastan’s published preparation method starts by mixing the product with a little hot water or milk, then adding the remaining liquid.

Use the dose on your packet. Stirring a small amount of liquid into the powder first is a useful way to make the drink evenly before filling the mug.

Moka pots, orziere and espresso equipment

Use barley labelled for the equipment concerned and follow both sets of instructions. Do not assume that the basket should be filled as it would be for coffee.

For example, Nestlé’s Orzoro Moka directions specify filling the filter only halfway, without pressing the barley down, and using a low flame. That is a product-specific instruction, not a rule to transfer automatically to every barley brewer.

Espresso-compatible barley products also exist. Hausbrandt’s instructions, for example, specify a dedicated filter for its barley pod. Do not put barley into a bean-to-cup machine’s hopper or ground-coffee chute unless the machine manufacturer explicitly permits it.

Barley tea

For a tea-style preparation, follow the bag or loose-grain instructions. Ippodo’s published hot-brew method uses one of its mugicha brewing bags with 1 litre of freshly boiled water at 100°C, infused for 10 minutes.

That quantity applies to its particular bag. Smaller bags and other products may require different water volumes.

Is barley coffee a healthy alternative?

The clearest practical distinction is caffeine: a pure barley drink is naturally caffeine free. That can make it an option when you want a roasted hot drink without caffeine, provided gluten is not a problem.

Check the ingredients rather than relying on the product name. Barley-and-coffee blends are sold, so “contains barley” does not necessarily mean “contains no coffee”. Blends may also include other cereals or roots.

Avoid transferring the nutritional reputation of whole barley directly to the drink. A 2024 laboratory study, not a clinical trial, examined roasted-barley teas made from three barley varieties and found that the prepared teas were not a source of dietary fibre or antioxidants under the conditions tested.

That does not establish the composition of every instant barley product or every brewing method. It does show why claims about the grain need separate verification before being applied to the beverage.

Likewise, measuring antioxidant activity in a laboratory does not establish that drinking a product prevents disease. Treat barley coffee primarily as a food choice, not a treatment for digestive symptoms or other medical conditions. Speak to a GP, pharmacist or dietitian about individual health concerns.

Choosing a barley drink you will actually enjoy

Choose by ingredients, preparation and serving style, in that order. First establish whether you can eat barley, then decide whether you want an instant mug, a brewed coffee-style drink or a lighter tea-style preparation.

For a plain starting point, look for barley as the sole ingredient. If you prefer a blend, read the complete list so you know what you are comparing. A drink containing chicory, coffee or several cereals should not be treated as representative of pure barley.

For a root-based comparison, read about chicory coffee. If you are comparing products promoted for additional functional ingredients, mushroom coffee needs separate consideration rather than being assumed equivalent.

The useful test for barley coffee is simple: does its roasted-grain character suit the drink you want? It need not impersonate espresso to earn a place in your cupboard.
