Whole Roasted Kernels vs Tea Bags

Whole roasted barley takes longer to brew but it’s my preferred method to make hot barley tea since the taste is so much more well-rounded and smooth than barley from tea bags.

Barley in tea bags are not whole barley kernels but crushed barley. Having smaller pieces means the brewing process is made quicker but it lacks the depth of flavor you get from the whole kernel.

For hot barley tea use whole kernels, and for iced barley tea use tea bags.

Questions You May Have

What does barley tea taste like?
It has a toasted, nutty taste. I hear it’s a bit of an acquired taste if you’ve never had it.

Is there caffeine?
Barley tea doesn’t contain any caffeine, which is why it’s great to drink all day and night.

Are there any calories?
Each serving has a whopping 2 calories.

Is barley tea a real tea?
Barley tea is a tisane, or an herbal tea so it’s not a real tea. Real tea has caffeine and comes from the camellia sinensis plant.

Do you add milk or sugar?
Milk or sugar isn’t added to traditional Korean barley tea. 

How do I store barley tea?
It’s best to store any type of tea and tea bags in an airtight container to avoid exposure to light, odor, and humidity.

How to Make Barley Tea Properly

STEP 1: Combine water and barley kernels in a kettle.

The best way to make hot barley tea is using whole roasted barley kernels instead of tea bags. (Tea bags are best for making iced barley.)

The formula is 1.5 teaspoons of barley kernels for every cup of water.

I usually make 4 cups at a time using a kettle with a mesh strainer so that’s using 2 tablespoons of loose whole roasted barley. 

The best tea is one made with the best water. Use filtered water. 

STEP 2: Bring to a boil, turn off heat, and steep for 5 minutes.

On the stovetop, bring the water to boil. After water comes to a boil, turn off heat and steep for 5 minutes. If you want a strong brew, steep it for 10-15 minutes.

Brewing it for longer will result in a darker color and stronger taste.

STEP 3: Strain barley kernels and pour hot tea into a teacup.

You’ve now got yourself a nice cup of barley tea!

Iced barley tea

How to Make Iced Barley Tea Properly

The best way to make iced barley tea is to cold brew it. Cold brewing is a method where you use cold water to slowly steep tea. 

Cold brewing takes longer than making hot tea and then cooling it down, but it’s my preferred method to making any type of iced tea.

STEP 1: Put barley tea bag and water in a pitcher or glass container.

No need to boil any water when it comes to cold brewing tea. Use cool or room temperature water.

As with any tea you make, use filtered water for the best tasting drink.

Each barley tea bag makes 4 cups, or one quart, of tea. I like using this cold brew glass pitcher.

STEP 2: Cover pitcher and put in the refrigerator for 1-2 hours.

STEP 3: Discard tea bag and pour tea into a cup. 

Because cold brewed tea is already chilled, you don’t need to add ice if you don’t want to.

    Thank you for this post. How to roast barley grains? In my country I don’t think I can find Barley tea bags but can find barley kernels. I want to try barley tea.

      Hi Maxat, I’ve never had to roast barley so I’m not sure I can provide an answer. I would start with toasting barley kernels on the stovetop, dry, for about 5-10 minutes until they brown.

    A simple popcorn maker is the ideal barley roaster. I use the whole grain Here is the method.
    How I make my mugachi. The most reasonable barley available to me is pot barley from bulk barn. It is slightly processed to remove most of the hulls, yet retain most of the berry. About 15 grams are used for a cup of finished tea, this is about a heaping tablespoon. I make a liter at a time which is very convenient about five cups.
    Method: Toast 3 minutes in a sunbeam popcorn maker. Stir while roasting to make homogeneous. The toasted barley is then put in the blender with one liter of water and beat into a slurry. This slurry is placed in a double boiler for steeping about 1.5 hours. This is just below boiling.The pulp and liquid mix well and make a complete drinkable liquid. I might add in the old days people did not have a blender, so my method hopefully improves on the process. This unique process utilized the whole barley grain.

    I roast my organic barley in the oven for 35 minutes at 350 degrees..
    it is a light roast which tastes more like a malted barley.
