How to Make Stevia Extract

I’m a drug addict. Some days it’s all I think about, that white stuff that makes me feel so good. But it’s not just the ubiquitous white granulated crystals that we all have stashed away. I’m equal opportunity. Molasses, coconut sugar, date sugar, honey, maple and agave syrup, c’mon over. I have an entire shelf dedicated to you guys. Sugar may be one of the biggest addictions today and we hook the kids when they’re young, barely old enough to walk.

At some point this year, about the time I realized two desserts a day were no longer enough to satisfy me, I faced the sober truth that I had a problem. No amount of healthy greens and grains – and I eat a lot of kale and quinoa – was going to offset this much sugar. I decided to eliminate sugar from my diet for one week, and because this is the age of social media, I found a buddy group through a Twitter party so I wouldn’t be traveling alone. I figured I could do anything for a week.

It wasn’t easy. Sugar is added to more foods than you would imagine. I was overwhelmingly aware of nightly bombardments of sugar-infused TV commercials after dinner. And all those sugar and chocolate treats deliberately placed within easy reach for the impulse buy while I waited to put my kale on the conveyor belt at the grocery store was just mean.

I wavered. Completely eliminating sugar just wasn’t realistic. I hopped online to research alternative sugars. Stevia shot to the top of the list with its carb- and calorie-free benefits. But like anything else connected with food these days, there was controversy. A lot of stevia on the grocery shelves is highly processed, with much of it mixed with various forms of sugar like dextrose. I couldn’t win.

And then I found a couple of plants at the nursery. You’d have thought I found a suitcase of money. I was that excited.

My first experiment was to dry some leaves and whirl them in a spice grinder. I added a pinch of the stevia powder to my morning yogurt and was thrilled with the result. It doesn’t take much to do the trick since the leaves are 30 – 50 times sweeter than sugar, and the sweetest part of the leaf is a mind-boggling 300 times sweeter.

The down side was the powder didn’t melt in my tea and I was tired of leaf bits in my mouth. It was just a little too natural. I needed to make stevia extract. It took two ingredients and 36 hours, but most of that time was spent sleeping, hanging out with friends, and writing.

The big question is always “How does it taste?” I’ll be honest, there’s a faintly bitter aftertaste, similar to some sugar substitutes, but less than I noticed in the powdered form. Whether I notice it at all is completely dependent on the food or drink I add it to. I notice a little aftertaste in my tea, although it’s not objectionable, but not at all in my plain yogurt or salad dressings. I should emphasize: the aftertaste can be managed somewhat through the amount of time the leaves steep in alcohol, and by the level heat applied at the end.

I can’t say I’ve completely kicked sugar. It’s work in progress, like most things. But when I get sugar cravings in the afternoons or evenings, I reach for a cup of tea sweetened with my stevia extract and some fruit. Often, that’s all I need. I’m down to only a couple of desserts a week, a huge improvement. Well, except for the month of October, of course, when we all take the October Unprocessed Challenge with Andrew.

Here’s how to make your own at home.

Homemade Stevia Extract

By: Susan Pridmore
Making your own stevia extract couldn’t be easier. But first you need a stevia plant. I’ve heard you can buy the leaves in some specialty stores, but have yet to see them. I’d love to hear from you if you’ve seen them out there. As a note, some people use both the leaves and stems, but I feel the stems add to the bitter aftertaste. I strongly recommend only using the leaves.
Prep: 10 minutes
Cook: 1 day 6 hours
Total: 1 day 6 hours 10 minutes
Servings: 1 bottle


  • Enough stevia leaves to fill a jar, don’t pack them too tightly, but they should be scrunched in
  • Enough vodka to cover the leaves


  • Wash the leaves, dry them, and stuff them into a clean jar. Fill the jar, loosely packing the leaves. The more leaves you have, the less time it will take to infuse the liquid.
  • Pour enough vodka into the jar to completely cover the leaves. Vodka is commonly used for many extracts because of its neutral flavor. Place a lid on the jar and set it on the counter for at least 24 hours. Test the liquid for sweetness. You’ll taste alcohol too, but just focus on the sweetness level. Continue to steep the leaves until you reach the amount of sweetness you want, but don’t go past 48 hours. Longer than 48 hours results in a dominant bitter flavor. I steep my leaves for 30 - 36 hours.
  • Place four layers of cheesecloth or a couple of coffee filters over the jar and strain the liquid into a small pot on the stove. Discard the leaves.
  • Warm the liquid over medium-low heat, being careful not to bring it to a boil. I keep it at barely a simmer with an occasional bubble or two. You’ll notice the alcohol burning off right away. Continue heating the liquid for 30 minutes. The extract will darken to pale amber, and dark particles will be apparent.
  • Strain the liquid again and pour into a small jar. The extract can be refrigerated for up to three months, so be sure to label the jar.

Hi, grew my first stevia plants, harvested today and am ready to load a jar with the leaves and add vodka. My son in NC has grown stevia for years and the plant has come back bigger each year. I am also going to hang and dry some for powder. It is amazing how sweet a leaf is. I purchased my seeds from Bear Creek Heirloom seeds.

My name is Joseph and I love your skill.
I must say u absolutely a champ… You though me nothing but perfection in these systematic way of preparing a STEVIA EXTRACT. I am a Ghanaian and most of us do much with sugar and other artificially made sweetners… I wish u can have a personal open forum down here in Ghana to educate us to a Better lifestyle…
U can also send me WhatsApp on +233241778105 ,so we have ample discussion. SUSAN, u are a Pro. Thank u

Great article thanks SO much! I purchased organic Stevia leaves c/s on Amazon through Starwest Botanicals in January this year (2018). I’m excited to make this! Can you tell me if I should use a nice Vodka or is cheapo ok since I will cook it off? Thanks!

I used to use Everclear to extract the Steviocides but recently switched to 151 proof Puerto Rican Rum because I do not eat grains. Any Grains. My process uses a warm water bath first. After careful multiple filtering I then wash the solution with the rum at a rate of 3 parts rum to 1 part stevia solution. After filtering several times the solution is decanted in a 1/2 gallon wide mouth Mason jar. After sitting for several days the solution is carefully siphoned off leaving a layer of very fine stevia leaf powder in the bottom of the jar. The Stevia extract does have an interesting “rum” flavor that completely masks the stevia flavor. Oh yeah one more thing…. Humans are NOT Herbivores. Humans need animal fat for optimal metabolic function. There is no rationalization that can change that nutritional fact. I am a retired chef with a doctorate… Read more »

Can you give me an idea of how much liquid to expect when finished with the heating process? For example if I use a 2 cup jar and then heat the infused vodka for 30 minutes how much of the original 2 cups of liquid should I be shooting for there to be left? Thanks!

You can use hot filtered water instead of vodka, although vodka is actually not a “no-no” for low-carbers (Atkins gives it a value of “0” net carbs).

I believe Betty (first comment) misunderstood the directions, as she was supposed to keep the extract simmering for 30 minutes to burn off the alcohol – not heat it up, then let it simply “steep” for 30 mins.
