Sparkling elderflower cordial is a simple recipe that lets biology do the “cooking,” while dazzling your taste buds with bubbly deliciousness. In this article, you’ll find out how to make it!   

Each year in late spring (usually between the last week of May and the first week of June in our area), a brief two week window of time opens, wherein one of the world’s most delightful culinary treats presents itself for harvest: elderflowers.

Elderflowers are the clusters of delicate white flowers adorning elderberry plants, a large shrub/small tree that thrives in temperate regions around the world. Ripe elderberries are also a prized food and medicinal crop.

We use our cultivated elderberries to make elderberry syrup. Interestingly, research has shown that elderberries boost the immune system and make a potent weapon against the cold, flu, and other viral pathogens.

How to harvest and process elderflowers

To make sparkling elderflower cordial, you’ll need to get elderflowers then remove them from the stems and pedicels.  

Step 1: Grow your own or identify wild elderberry plants to source elderflowers.

We have five large, mature elderberry plants growing in our yard, and within a few miles of our house, there are dozens of other wild elderberry plants growing. If elderberry plants are native to where you live (they likely are) and you know how to ID them, you’ll see elderberry plants everywhere while they’re in bloom.

However, even without foraging the wild plants growing nearby, our five elderberry plants produce more than enough flowers and berries to last us the year without negatively impacting fruit production. 

Step 2: Remove whole flower clusters when flowers are open but still bright white.

We harvest whole flower heads when the tiny star-shaped flowers are still bright white, since the flavor is at peak during this stage. Once the flowers have turned tan/brown, they won’t contain the nectar and pollen to produce their famous, delicate flavor.

We cut whole flower heads off of the plant in the early morning before our pollinators have had a chance to forage their pollen and nectar. Obviously, this means those branches won’t be able to produce berries, so we only take as many flower heads as we need.

Also, we only remove flowers from branches on the outermost branches that would be likely to snap under the full weight of a ripening berry cluster (their branches are quite brittle). We leave the flowers on the strongest, most upright branches for a berry harvest, allowing us to maximize the full benefits of the plant.

When harvesting, we’ll place the flower heads in large 5 gallon buckets or a woven harvest basket. We can harvest all the elderflowers we need for the year in about 30 minutes.

Step 3: The hard part – removing all the flowers from the stems/pedicels.

Once harvested, we immediately bring the flower clusters inside to be removed from the stems by hand. This is by far the most laborious part of the process. 

This is what a pile of elderflowers should like (removed from the stems) before you make them into sparkling elderflower syrup.

It should take one person an hour or less to strip four cups of elderflowers from their stems. We don’t know of any easy way to do it – we just swipe down the stems towards the flowers with our fingertips repeatedly until all the flowers are removed. 

Oh, and since each elderberry plant and flower cluster is its own ecosystem, you will encounter some tiny insects during this process. That’s ok. Put them back outside.

Worst case scenario is a few tiny insects become part of your sparkling elderflower cordial, which isn’t a problem. You already eat about 2 pounds of insects every year, so a few more won’t hurt you.

If insects really bother you, you can also make this recipe using these dried organic elderflowers that someone else already processed.

How to make sparkling elderflower cordial 

Sparkling elderflower cordial achieves its delightful bubbles via a natural fermentation process. The beneficial microbes you harness in the process (primarily native yeasts and bacteria on the elderflowers) create the magic for you, similar to the beer and wine-making process.

Sparkling elderflower syrup has an incredible flavor that words just won't do justice to.

Sparkling elderflower cordial makes a delightful, lightly alcoholic disgestif (probably no more than 2-3% alcohol) to sip after a meal or just because you want to. Of course, before serving, you can also fortify your sparkling elderflower cordial with a non-flavored, colorless spirit like vodka to make it more akin to the famous St-Germain elderflower liqueur made in France.

Here’s the simple recipe we’ve developed to make our sparkling elderflower cordial:

Course: Drinks, Health Drink / Syrup

Prep Time: 1 hour
Fermentation time: 7 days
Servings: 100 shot glasses

A simple fermented sparkling (bubbly) cordial made with fresh or dried elderflowers.


  • 4 cups fresh-picked elderflowers
  • 8 cups water
  • 4 cups organic raw cane sugar
  • 3/4 cup organic lemon juice ideally fresh-squeezed OR 2 tablespoons citric acid


  1. Place elderflowers in a large glass or non-reactive container (not plastic).
  2. Add sugar and water to a pot on the stove. Warm the water just enough to dissolve the sugar in the water while whisking - not so warm that it's uncomfortable to touch.
  3. Pour the sugar water mixture over the elderflowers, then add in your lemon juice or citric acid. Stir to ensure all ingredients are evenly mixed together. The flowers will soon float back to the surface.
  4. Cover the container with a BREATHABLE cloth/linen towel and secure the towel with a string or rubber band.
  5. Stir the mixture every 12 hours. Start taste-testing the syrup at the 48 hour mark. Exactly when it's "ready" is subjective and will also change based on indoor temperatures and the activity of resident microbes in the mix. Our sparkling elderberry syrup is usually perfect for us at the end of day 5-7, but your preferences may be different.

  6. Once done, pour the mix through a strainer and into another large container to remove all the flowers. Squeeze all the goodies out of the strained flowers by hand, then compost them.
  7. Pour the final syrup into jars/bottles and refrigerate immediately to make the microbes go dormant and halt the fermentation process. Refrigerated, sparkling elderberry syrup can last for months.


We hope you enjoy this recipe for years to come! If you want to grow your own elderberry plants for flower and berry harvests, you can buy them here.

    I’m about to make wisteria cordial.
    Is that 3 to 4 cups of lemon juice or 3/4 of a cup?

    Good morning! I’m curious when you fortify the cordial with vodka, what is the ratio of vodka to cordial?

    Thank you,

      Hi Ally! That’s going to completely depend on your taste preferences. However, since this elderflower cordial recipe is a living probiotic, you might want to only fortify it right before serving to try to keep the probiotic microbes alive.

    Hello! Can you substitute honey or agave for the sugar?

      You can substitute honey 1:1 with sugar in this elderflower recipe. We’ve done that before and it works well but it does make the final elderflower cordial flavor more honey-forward (sugar is more neutral in flavor). I’m not sure about agave – probably so, but just haven’t done it, so I can’t say for certain. Enjoy!

    Since the beverage has an alcohol content that is not negligible, what would you consider the classification? Unfortified wine?

      We’ve never actually measured the alcohol content in our elderflower sparkling cordial but it’s WAY under the level of an unfortified wine, which is usually in the 12% ABV range. If we had to guess, it’s somewhere in the 3% or less range. Which puts it more in line with something like kombucha. Kind of its own thing…

    Hello, I am new to this and wanted to make wisteria. Do I have to take off the little stem and cap that is on the bottom of the blossom?

      The tiny stems and caps at the very base of wisteria flowers are fine. What you don’t want to include is the main stem running the length of the wisteria flower cluster, leaves, or any other part of the wisteria plant. (The wisteria pods that form AFTER flowers have set and developed are also poisonous.)

    Hi! I am making this with wisteria petals, are all wisteria types edible? Not sure which plant in particular we have, Also, we are maybe at day 5 of making this and there are white specks floating on top, is this normal?

      Hi Amber! As far as we know, all wisteria petals/flowers are edible, but we’re hesitant to make that guarantee in the event that there are bred varieties or unknown hybrids out there that might not be edible. As the article mentions (and we should repeat here). all other parts of the wisteria plant are poisonous, including the pods. As for the white specks, hopefully that’s harmless kahm yeast, but it’s tough to say without seeing it. Perhaps you can google “kahm yeast” and see if that’s what you’ve got? If you’re vigorously stirring the mixture at least twice per day, kahm yeast shouldn’t be forming, so make sure to stir, stir, stir!

        Thank you! It could be Kahm yeast. Its the tiniest specks of it though so a little hard to tell and seem to be hard to see now that bubbles are starting. I’ll keep stirring!

    Whats the recommended amount of dried flowers instead of fresh?

      Aron, We’ve never used dried elderberry flowers since we have elderberries growing all around our house and only make this recipe when they’re flowering. Our guess is that you’d probably want to AT LEAST double the quantity of dry flowers relative to fresh flowers in this recipe. You should know whether or not the dried flowers you’ve put in add enough flavor within 4-5 days – if not you can always add more and keep going. If you give this recipe a try with dried elderberry flowers, please let us know how it turns out + any tips/recommendations for other people!
