How to Make Stevia Extract

You will need:

Fresh stevia leaves (Dry leaves can work too–see the note below)


Clean glass jar with lid

The amount of ingredients you need will depend on how much stevia extract you want to make. I made a fairly small batch this time around, so I only ended up using about 1 cup of vodka, and a handful of chopped leaves. Depending on how many stevia plants you have, you can make a big batch, or just a small one.

1.Wash the leaves and remove them from the stem. Discard any wilted or brown leaves, and coarsely chop the rest.

2.Place the leaves into a clean, glass jar. I filled my jar to the top, but I didn't pack the leaves down.

3.Fill the jar with vodka, making sure the leaves are completely covered.

Place the lid on securely, and give it a good shake and set it aside.

Let the leaves steep in the vodka for around 48 hours. This is a much shorter time frame than many other extracts, but if you let it sit more than a day or two, the resulting stevia extract is pretty darn bitter.

After 48 hours, strain the leaves from the vodka (I also gave my leaves a good squeeze to smoosh out every last bit of extract).

Pour the extract into small saucepan and heat it gently for 20 minutes. Do not let it boil, just warm it up to remove the alcohol and improve the sweetness. It will also thicken up a bit and reduce in volume.

4.Pour your finished extract into a small bottle (I like one with a dropper–it makes it easier to use) and store it in the fridge. It should last several months.

stevia leaf uses

How to make stevia extract without alcohol

There are several ways to make your liquid stevia, which can be used by the drops or dropper-full in drinks and recipes. To create these solutions you can basically choose between three different solvents or combinations of all three:


pure water


These substances will dissolve the plant material or powder and hold it in suspension.

Below we have several recipes on how to make stevia extract using these assorted menstruums utilizing either fresh stevia, dried leaves, ground leaf powder as well as white stevia sugar.

how to make stevia extract with water

To make a stevia liquid solution using straight water, we tend to use either the green powder or a white powdered extract. Both have their advantages and disadvantages.

Green leaf powders are higher in nutritional components and are a whole food sugar that is potentially better for the body long term. However, these powders, ground from the dried leaves, do tend to have an strong aftertaste.

This dark green version can be made by infusing the powder in hot water or making an unheated solution, depending on your preference. We prefer using freshly ground dried stevia leaves and opposed to purchased pre-powdered leaves.

The white stevia sugars, like the one from Omica Organics, dissolve better in water and don't need to be filtered out, plus they are more palatable for some people. You also don't need to use as much per recipe as they are highly concentrated in steviol glycosides. This type of liquid concentrate is very simple to make and does not require a hot water infusion.

Although this variety is closer to manufactured stevia liquids, it is much cheaper to make yourself.

When making water based stevia solutions it is sometimes good to use a little bit of alcohol or glycerin to preserve it.

How to make stevia extract at home

How to make stevia extract at home

To make stevia extract, you need three simple things:

Stevia Leaves (fresh or dried)

Neutral Vodka

A Jar

That’s it. It’s hard to make this sound like a recipe because it isn’t. Pull the stevia leaves off the branches, put them into the jar, cover them with vodka. Chop the stevia leaves before putting them in the jar, or don’t, it’s up to you. Let the leaves steep in vodka for about 2 days, any longer and the extract can get bitter. Unlike when you’re making a homemade tincture, you don’t want to extract everything out of the leaves, just their simple sweetness.


If you are wanting to make sure your stevia is pure, then try making it yourself. Growing stevia is super easy. You can pick up a stevia plant at your local nursery and I have also seen them at home improvement stores in their garden centers. Stevia plants have become very easy to find these days.

Stevia can be grown in pots, in landscapes, and in gardens. You can even grow stevia indoors. It requires very little maintenance. It can be harvested all summer long but is sweetest in the fall when the temperatures become cooler.

When your stevia is ready to harvest (you can view my stevia that is ready for harvest in the video below) then follow these simple steps to make your own pure stevia and liquid stevia.

Harvest your stevia plant by cutting off the branches at the base of the plant.

Wash the branches/leaves in clean filter water.

Pick leaves off stevia plant, discard the stems, and dry the leaves for 12 hours in the sun.

Once your leaves are dry, grind them in a food processor or coffee grinder to make pure stevia. I find that a coffee grinder makes for the finest powder and works very nicely.

Note ~ homegrown stevia powder is not as sweet as store bought stevia (300 times sweeter than sugar). To cook with home grown stevia simply replace every 1 cup of sugar with 3-4 teaspoons of homegrown stevia.

To make liquid stevia, dissolve 1/4 cup pure homegrown stevia powder with 1 cup hot filtered water. Stir and leave out at room temperature for 24 hours. After 24 hours strain the stevia out of the liquid and store the liquid stevia in the refrigerator.

How to make stevia syrup

How to make stevia syrup

Your dry stevia leaves can be used to make a healthy syrup for sweetening beverages, sauces, or even other syrups. A teaspoon of stevia syrup is as sweet as a cup of sugar.

Take 2 cups of warm water and add it to half a cup of dried stevia leaves. Put the mixture in a glass jar and let it steep for 24 hours. Strain the leaves from the mixture.

Cook the strained mixture on low heat, reducing it to a concentrated syrup. The syrup should last for at least a year if kept in an airtight container in your refrigerator.

How to make white stevia powder

Homemade stevia powder isn’t any harder than extract.

If you have fresh stevia leaves, they’ll need to be dried first. Lay them out in a well-ventilated area, or chop the plants off at the base and hang them whole from a rafter. Either way, they’re reasonably dry to start with and it should only take a few days to dry them completely.

If you’re in a very humid area, try drying them in the oven on the lowest setting. Once they’re dry enough to completely crumble in your hands, they’re ready.

Starting with store-bought dried stevia leaves, you’re ready to go.

A handful of fresh stevia leaves ready to be dried for homemade stevia powder.

The next step, turn the leaves into a powder.

The easiest way to do this is a clean coffee grinder, one of those tiny cheap blade grinders. It’s important that it’s never been used, not even once, to grind coffee though. I keep one separate just for grinding herbs, and the herbs don’t leave their flavor in it as coffee would.

Place a few dried leaves in the grinder and pulse until it’s a powder.

Since homemade stevia powder is actually powdered stevia, instead of lab-made powdered erythritol flavored with stevia, it takes considerably more in to get the same effect in recipes. It’s still much sweeter than sugar, and you only need about 1/8 to 1/4 cup of homemade stevia powder to replace a cup of sugar.

When using it in recipes calling for powdered stevia, you may need to add a bit more than the recipe calls for. It’ll depend on your tastes, and the sweetness of your particular plant.

How to make stevia crystals

Re-crystallization is a process where the stevia extract from step 5 is dissolved in a mixture of water and food grade ethanol. The mixture is then cooled down at which point the steviol glycoside found in the highest concentration will start to crystallize. By doing this a separation of different steviol glycosides can be obtained.

How to use stevia powder

It is used as a non-nutritive sweetener and herbal supplement. A non-nutritive sweetener is one that contains little to no calories. Stevia is used as a healthful alternative to added sugar in many meals and beverages.

When taken by mouth: Stevia and chemicals contained in stevia, including stevioside and rebaudioside A, are LIKELY SAFE when taken by mouth as a sweetener in foods. Rebaudioside A has generally recognized as safe (GRAS) status in the U.S. for use as a sweetener for foods. Stevioside has been safely used in research in doses of up to 1500 mg daily for 2 years. Some people who take stevia or stevioside can experience bloating or nausea. Other people have reported feelings of dizziness, muscle pain, and numbness.
