PART 1: What is Rhubarb Soda?

Understanding Rhubarb Soda and Its Origins

Rhubarb soda is a lightly carbonated beverage made by combining rhubarb syrup or juice with soda water. It has a crisp, tangy flavor that’s both refreshing and energizing. This drink has seen a revival among homemade beverage lovers due to its simplicity, flavor, and nostalgic roots. In fact, soda fountains in the early 20th century often served it as a tonic for digestion and mild ailments.

Now, it’s making a comeback in modern kitchens as people explore fizzy, colorful drinks without artificial additives. Its naturally blush-pink hue also makes it an Instagram-worthy addition to any beverage menu.

Check out our White Linen Cocktail Guide for more DIY drink inspiration that blends classic and contemporary flavors.

The History of Rhubarb as a Beverage Flavor

While rhubarb might be best known for its role in pies, its transition to beverages was a natural one. Historically used in traditional Chinese medicine for its detoxifying qualities, rhubarb’s tart stems became a beloved ingredient in everything from syrups to tonics. In Europe, especially Germany, “Rhabarberschorle” is a popular fizzy rhubarb drink still enjoyed today.

The plant’s punchy taste makes it ideal for soda-making especially for those avoiding overly sugary drinks. Want to keep your flavors balanced and healthy? You might enjoy our roundup of Gluten-Free Italian Salad Dressing and how to build flavor naturally.

PART 2: Health Benefits of Rhubarb Soda

Nutritional Profile of Rhubarb

Rhubarb may look like a stalky fruit, but it’s technically a vegetable and a nutritional powerhouse at that. When used to make rhubarb soda, especially in homemade versions, it retains some of its natural benefits without the excessive sugar found in commercial sodas.

Here’s a quick breakdown of rhubarb’s nutritional value per 100g (raw):

The vitamin K content in rhubarb is especially notable—it helps with blood clotting and bone metabolism. The stalks also contain polyphenols and antioxidants that fight inflammation and support digestion, which makes rhubarb soda a better choice than traditional carbonated soft drinks when made with real rhubarb.

How Rhubarb Soda Supports Digestion and Wellness

Rhubarb has long been used in herbal medicine as a digestive aid. Its mild laxative effect can help relieve bloating and constipation when consumed in moderation. When you sip on rhubarb soda especially a fermented version you’re also getting the added benefit of probiotics if prepared properly.

Fermented rhubarb soda made with whey, kefir, or ginger bug not only boosts gut health but also supports your immune system. It’s a great alternative for those looking to transition away from sugary sodas while still enjoying a carbonated beverage.

And let’s not forget hydration. Since rhubarb soda is water-based, it contributes to your daily fluid intake without artificial ingredients or caffeine.

PART 3: Homemade Rhubarb Soda Recipes

Classic Rhubarb Simple Syrup Base

At the heart of every good rhubarb soda is a bright, tart, and vibrant rhubarb syrup. This simple syrup is made by simmering chopped rhubarb with water and sugar until it breaks down into a beautiful pink elixir. Once strained, you can mix it with chilled sparkling water to create a refreshing homemade soda that’s as visually appealing as it is flavorful.

Basic Rhubarb Syrup Recipe:

Steps:

1. Combine rhubarb, sugar, and water in a saucepan.
2. Bring to a boil, then simmer for 20–25 minutes until rhubarb breaks down.
3. Strain using a fine mesh sieve or cheesecloth.
4. Let the syrup cool, then store it in the fridge for up to two weeks.

This syrup serves as the perfect base for rhubarb soda, but can also be used in cocktails or drizzled over desserts. For other easy-to-prep bases, check out our post on Gluten-Free Italian Salad Dressing—a great reference for mastering flavor balance.

Natural Fermentation vs. Soda Water Method

There are two main ways to carbonate your homemade rhubarb soda: the quick-and-easy soda water method or the slow-but-natural fermentation approach.

1. Soda Water Method

This is the simplest method. Just add 3–4 tablespoons of rhubarb syrup to a glass of cold soda water or sparkling mineral water, stir, and enjoy. You can adjust the syrup ratio depending on how sweet or tart you prefer your soda.

2. Fermentation Method

This method creates a naturally fizzy drink and can even introduce beneficial probiotics.

Fermented Rhubarb Soda Base:

Steps:

1. Combine all ingredients in a swing-top glass bottle.
2. Seal and let ferment at room temperature for 2–3 days.
3. Open carefully to release pressure and check carbonation.
4. Once fizzy, refrigerate and serve cold.

This method results in a mild tang and a bubbly texture, much like kombucha. If you love experimenting with fermentation, our article on Cloud Coffee Drink may inspire other unique homemade beverages.

PART 4: Rhubarb Flavor Explained

What Does Rhubarb Taste Like?

If you’ve never tasted rhubarb, you’re in for a surprise. Rhubarb has a distinctively tart, almost lemony flavor that’s both sharp and refreshing. When cooked, it mellows slightly and develops a soft, almost floral aroma. This tang is exactly what makes rhubarb soda so invigorating it’s a crisp alternative to sugary fruit sodas.

Raw rhubarb has a crunchy texture and astringency that can make your mouth pucker, but once simmered into a syrup, its acidity balances beautifully with sweeteners like honey, cane sugar, or agave. The resulting flavor in soda is bright, zesty, and clean perfect for hot summer days or pairing with rich meals.

Why Rhubarb is Often Paired with Strawberries

It’s no accident that rhubarb and strawberries are one of the most beloved food duos. Strawberry’s natural sweetness softens rhubarb’s sour edge, creating a perfectly balanced flavor profile. The juicy, fragrant notes of strawberries round out rhubarb’s tartness, resulting in a soda that tastes complex, fruity, and irresistibly fresh.

That’s why rhubarb soda variations often include strawberry slices or purée. Together, they bring a depth of flavor and a rich pink hue that’s both nostalgic and modern. If you’re into flavor balancing, check out our Gluten-Free Chips article for more ideas on pairing salty, sweet, and sour components.

For a full-on fruity twist, combine rhubarb syrup with muddled strawberries and a splash of lime over ice. You’ll get a homemade soda that rivals anything from boutique soda brands.

PART 5: Crafting Rhubarb Fizz and Other Variations

What is Rhubarb Fizz and How to Make It

A rhubarb fizz is a delightfully sparkling drink made by combining rhubarb syrup with soda water and sometimes a splash of citrus or spirit. It’s similar to rhubarb soda but typically includes added effervescence and layers of flavor—making it a perfect non-alcoholic cocktail or a refreshing low-proof sipper.

Here’s a simple recipe for a homemade rhubarb fizz:

Rhubarb Fizz Recipe:

PART 6: Is Rhubarb Safe and Healthy?

Is Raw Rhubarb Safe to Eat?

Yes rhubarb stalks are safe to eat raw, though they are extremely tart and fibrous. However, you should never eat rhubarb leaves, whether raw or cooked. The leaves contain high levels of oxalic acid and anthraquinone glycosides, which are toxic and can cause nausea, breathing difficulty, and kidney problems if consumed in large quantities.

When preparing your own rhubarb soda, always trim and discard the leaves immediately after harvesting or purchasing. The edible stalks are what you’ll be using to make syrup or juice. While they’re safe raw, most people find the taste more enjoyable once cooked with a sweetener.

Curious about how to build more naturally healthy meals? Our post on Gluten-Free Dairy-Free Soup showcases how to safely work with veggies and balance flavors cleanly.

Why You Shouldn’t Eat Too Much Rhubarb

While the stalks of rhubarb are non-toxic, eating excessive amounts of rhubarb especially raw can irritate the stomach due to its high oxalate content. This is more of a concern for people prone to kidney stones, since oxalates can bind to calcium and contribute to stone formation.

However, when rhubarb is cooked down into syrup for rhubarb soda, oxalate levels are significantly reduced. Plus, you’re consuming it in much smaller, diluted quantities than eating whole stalks. So unless you’re downing gallons of rhubarb syrup, there’s little cause for concern.

Safety Quick Tips for Rhubarb:

PART 7: Rhubarb – Fruit or Vegetable?

Botanical Classification of Rhubarb

Technically speaking, rhubarb is a vegetable. It comes from the Rheum genus and is closely related to buckwheat and sorrel. Rhubarb grows in long, celery-like stalks that range in color from green to deep crimson. These stalks are the only edible part of the plant—the large, fan-shaped leaves are toxic and must be discarded.

Despite being a vegetable, rhubarb is legally classified as a fruit in the United States. This happened in 1947 when a New York court ruled that rhubarb should be taxed as a fruit due to its culinary use—mainly in pies, jams, and drinks. Since then, it has held an unusual dual identity: a veggie by botany, a fruit by kitchen standards.

This odd identity is what makes rhubarb soda so unique. It’s a fizzy, fruity beverage technically made from a vegetable. If you love unexpected twists in your recipes, you’ll enjoy our Gluten-Free Soup, which flips the script on comfort food with plant-based ingredients.

How Rhubarb is Used in Culinary Contexts

In the kitchen, rhubarb plays the role of a fruit thanks to its sour flavor and compatibility with sugar, berries, and citrus. You’ll find it baked into desserts, pureed into sauces, and, of course, simmered into syrup for rhubarb soda.

Its natural acidity also makes it a great ingredient for savory-sweet glazes and pickling. In some modern dishes, chefs are even using rhubarb in salsas or to top meats—pushing it far beyond the classic pie stereotype.

Here’s how rhubarb is commonly used:

PART 8: Bottling and Serving Your Rhubarb Soda

Homemade Carbonation and Storage Tips

Making your own rhubarb soda is incredibly satisfying, but bottling it correctly is just as important for safety and flavor. Whether you’re using the soda water method or opting for natural fermentation, the right storage makes all the difference in taste and shelf life.

For Soda Water Method:

• Store your rhubarb syrup in a sterilized glass jar in the fridge. It’ll keep for about 2 weeks.
• Mix the syrup with soda water just before serving to maintain carbonation.
• Use chilled sparkling water or seltzer for best fizz results.

For Fermented Rhubarb Soda:

• Use swing-top glass bottles (also known as Grolsch bottles). These can withstand pressure and help build natural fizz.
• Allow fermentation at room temperature for 2–3 days. Then, “burp” the bottles daily to prevent pressure build-up.
• Once carbonated, refrigerate immediately to slow fermentation and preserve flavor.
