A gin and tonic is undeniably a classic and refreshing drink. The story of its origin, with its anti-malarial properties derived from quinine that protected the British in India and Africa, adds a layer of historical complexity. However, commercial tonic water from big brands has seen a decline in quality, often containing barely any quinine. While several high-quality tonic options exist, such as Q, Fever Tree, and Fentiman’s, their cost and availability can be limiting. This article explores how to craft your own diet tonic syrup, offering a cost-effective and customizable alternative.
Why Make Your Own Tonic Syrup?
Creating your own tonic syrup offers several advantages:
- Cost-Effectiveness: Homemade syrup can be significantly cheaper than purchasing premium tonic waters.
- Customization: You have complete control over the ingredients, allowing you to adjust the flavor profile to your liking.
- Quality Control: You can ensure that your tonic contains high-quality ingredients and the desired level of quinine.
- Dietary Control: By making your own syrup, you can control the sugar content and create a diet-friendly version.
Key Ingredients and Their Roles
Making diet tonic syrup requires sourcing some specific ingredients, but the ability to tailor the flavor and reduce sugar makes the effort worthwhile. Here's a breakdown of the key components:
- Cinchona Bark (Quinine Source): This is the essential ingredient that provides the characteristic bitter flavor and anti-malarial properties of tonic. Cinchona bark contains quinine, the active compound.
- Citrus: Lemon, lime, and orange peels are commonly used to add tartness and complexity to the tonic syrup.
- Botanicals: A blend of herbs and spices contribute to the aromatic profile. Common choices include:
- Juniper Berries: Adds a piney, gin-like note.
- Coriander Seeds: Lends a citrusy and slightly spicy flavor.
- Cardamom Pods: Provides a warm, aromatic spice.
- Angelica Root: Offers an earthy, slightly bitter flavor.
- Sweetener: To keep the recipe diet-friendly, a sugar substitute is required.
- Water: The base for the syrup.
- Everclear (or High-Proof Neutral Spirit): Used to extract quinine from the cinchona bark.
- Gentian (Optional): For more assertive bitterness.
Adapting Jeffrey Morgenthaler's Inspiration
Many homemade tonic recipes are inspired by Jeffrey Morgenthaler's recipe from 2008. His recipe serves as a great starting point, but many find that it can be a bit muddy. This article will explore adjustments to achieve a cleaner, more refined flavor.
Crafting the Quinine Tincture
The first step involves extracting quinine from the cinchona bark. This is typically done by creating a tincture:

- Mix the cinchona powder with Everclear (or another high-proof neutral spirit).
- Cover the mixture and let it sit overnight.
- Strain the mixture through a coffee filter fitted on your finest mesh strainer (or filter cone) into a container. This process may take some time.
- Strain again through a second coffee filter to remove any remaining fine particles.
This tincture will be the source of quinine in your tonic syrup. It is important to limit the amount of quinine added to the final beverage.
Preparing the Botanical Syrup
The next step is to create a syrup infused with the flavors of citrus and botanicals:
- Add all the botanical ingredients (citrus peels, juniper berries, coriander seeds, cardamom pods, angelica root, etc.) to a medium saucepan.
- Add water and sweetener to the saucepan.
- Heat over medium-high heat until the mixture comes to a boil.
- Reduce heat to low, cover, and simmer for 20 minutes.
- Strain the syrup through a mesh strainer and let it cool.
Combining Tincture and Syrup
Once the quinine tincture and botanical syrup are prepared, they need to be combined:
- Measure out the specified amount of the quinine tincture (e.g., 45 ml or 1 1/2 ounces).
- Mix the tincture into the cooled botanical syrup.
- Store the remaining quinine tincture in an airtight container (it will keep indefinitely).
- Store the finished syrup in an airtight container in the refrigerator.
Serving and Enjoying Your Diet Tonic Syrup
To enjoy your homemade diet tonic, simply mix it with soda water. The ratio can be adjusted to taste, but a common starting point is 1 part syrup to 4 or 5 parts soda water. Add gin (or an alcohol-free spirit alternative) for a classic gin and tonic.
Considerations for a Diet Version
To make a diet tonic syrup, it's essential to replace traditional sugar with a suitable sugar substitute. Some popular options include:

- Erythritol: A sugar alcohol with a mild sweetness and minimal impact on blood sugar.
- Stevia: A natural sweetener derived from the stevia plant.
- Monk Fruit Sweetener: Another natural sweetener with zero calories and a low glycemic index.
- Allulose: A rare sugar that is not metabolized by the body, resulting in very few calories.
The choice of sweetener will depend on personal preference and dietary needs. It's important to experiment with different sweeteners to find one that provides the desired level of sweetness without any unpleasant aftertaste.
Customization and Flavor Variations
One of the best things about making your own tonic syrup is the ability to customize the flavor profile. Here are some ideas for variations:
- Citrus Variations: Experiment with different combinations of citrus peels, such as grapefruit, blood orange, or Meyer lemon.
- Spice Variations: Add other spices like star anise, cloves, or allspice for a warmer, more complex flavor.
- Floral Notes: Infuse the syrup with edible flowers like lavender or rose petals for a delicate floral aroma.
- Herbal Infusions: Add fresh herbs like rosemary, thyme, or basil for a savory twist.

Additional Tips and Considerations
- Sourcing Ingredients: While some ingredients like cinchona bark and angelica root may not be available at your local grocery store, they can be easily found online.
- Adjusting Sweetness: The amount of sweetener can be adjusted to taste. Start with a smaller amount and add more as needed.
- Filtering: Filtering the syrup through a coffee filter can help remove any sediment and create a clearer final product.
- Storage: Homemade tonic syrup should be stored in an airtight container in the refrigerator and will typically last for several weeks.
- Sustainability: Consider using recyclable packaging and sourcing ingredients from responsible suppliers to minimize your environmental impact.
Addressing Potential Issues
- Bitterness: If the tonic syrup is too bitter, try adding a small amount of sweetener or a pinch of salt to balance the flavors.
- Cloudiness: If the syrup is cloudy, try filtering it again through a coffee filter.
- Flavor Imbalance: If the flavors are not well-balanced, experiment with adjusting the amounts of different ingredients until you achieve the desired taste.
