Understanding Food Grade Lavender Extract

Food grade lavender extract is a concentrated flavoring agent derived from lavender flowers. It captures the essential oils and aromatic compounds responsible for lavender’s distinct flavor and scent. Unlike essential oils, which are highly concentrated and not meant for direct ingestion in most cases, food grade extract is prepared in a way that makes it safe and suitable for adding to food and drinks.

The primary difference between culinary and non-culinary lavender products lies in the variety of lavender used and the extraction process. Food grade lavender must be made using lavender varieties known for their sweet and less camphoraceous flavor profiles. It must also be prepared using food-safe solvents and equipment.

Choosing the Right Lavender for Extraction

Selecting the appropriate lavender variety is crucial for achieving the desired flavor profile in your extract. Not all lavender is created equal, and some varieties are better suited for culinary use than others.

Lavandula angustifolia, also known as English lavender or true lavender, is the most commonly recommended variety for culinary applications. It has a sweet, floral aroma and a less pronounced camphoraceous taste compared to other species. Within the Lavandula angustifolia species, cultivars like ‘Munstead,’ ‘Hidcote,’ and ‘Vera’ are popular choices due to their excellent flavor.

Avoid using Lavandula x intermedia, also known as lavandin. While lavandin produces a higher yield of essential oil, it has a stronger, more camphoraceous scent and flavor that can be overpowering in food.

Ensure that the lavender you choose is organically grown and free from pesticides or herbicides. This is particularly important for food grade applications, as you don’t want to introduce any harmful chemicals into your extract. If you are growing your own lavender, avoid using any synthetic fertilizers or pest control products.

Selecting the Right Solvent

The solvent used in the extraction process plays a vital role in determining the quality and safety of your lavender extract. For food grade applications, it’s essential to use a solvent that is both effective at extracting the flavor compounds and safe for consumption.

Food grade alcohol, such as vodka or brandy, is the most common and recommended solvent for making lavender extract. Choose a high-proof alcohol (80 proof or higher) to ensure efficient extraction. The higher the alcohol content, the better it will extract the essential oils and preserve the extract. Vodka is a popular choice due to its neutral flavor, which allows the lavender’s flavor to shine through. Brandy can add a subtle fruity note to the extract.

Avoid using isopropyl alcohol or rubbing alcohol, as these are toxic and not safe for consumption. Make sure the alcohol you select is explicitly labeled as “food grade.”

Glycerin can also be used but results in a less potent extract. However, some people prefer glycerin-based extracts for alcohol sensitivities or to reduce overall alcohol content.

Essential Equipment for Making Lavender Extract

Before you begin, gather all the necessary equipment to ensure a smooth and efficient extraction process.

A clean glass jar with an airtight lid: The size of the jar will depend on the amount of extract you want to make.
A sharp knife or scissors: For chopping or cutting the lavender flowers.

Step-by-Step Guide to Making Food Grade Lavender Extract

Now that you have your ingredients and equipment ready, let’s walk through the step-by-step process of making food grade lavender extract.

Prepare the Lavender: Harvest the lavender flowers when they are at their peak bloom, typically in the morning after the dew has dried. Gently rinse the flowers to remove any dirt or debris. Pat them dry with a paper towel. Remove the flowers from the stems and coarsely chop them. Chopping the flowers helps to release their essential oils and aromatic compounds.
Combine Lavender and Alcohol: Place the chopped lavender flowers into the clean glass jar. A general guideline is to use about 1/2 cup of fresh lavender flowers per cup of alcohol. However, you can adjust the ratio to your preference. Pour the food grade alcohol over the lavender flowers, ensuring that they are completely submerged. Use a spoon to gently press the flowers down if necessary.
Infuse the Lavender: Seal the jar tightly with the lid. Place the jar in a cool, dark place, such as a pantry or cupboard. Allow the lavender to infuse for at least 4-6 weeks, or even longer for a more concentrated flavor. Shake the jar gently every few days to ensure that the lavender flowers are evenly exposed to the alcohol. This helps to facilitate the extraction process.
Filter the Extract: After the infusion period, it’s time to filter the extract. Place a fine-mesh sieve or several layers of cheesecloth over a clean bowl or jar. Pour the lavender-infused alcohol through the sieve or cheesecloth, allowing the extract to drip into the container. Gently press the lavender flowers to extract as much liquid as possible. Discard the spent lavender flowers.
Store the Extract: Transfer the filtered lavender extract into a dark glass bottle with a dropper. Label the bottle with the date and ingredients. Store the extract in a cool, dark place, away from direct sunlight and heat. Properly stored lavender extract can last for several years.

Tips for Making the Best Lavender Extract

Use Fresh Lavender: While dried lavender can be used, fresh lavender flowers will yield a more vibrant and flavorful extract. If you must use dried lavender, reduce the amount by half, as dried herbs are more concentrated.
Be Patient: The longer the lavender infuses, the stronger the flavor of the extract will be. Don’t rush the process.
Adjust the Ratio: Experiment with different ratios of lavender to alcohol to find the flavor intensity that you prefer.
Use High-Quality Alcohol: The quality of the alcohol will affect the taste of the extract. Choose a high-proof, neutral-flavored alcohol for the best results.
Store Properly: Proper storage is crucial for preserving the quality and flavor of your lavender extract. Store it in a dark glass bottle in a cool, dark place.

Using Your Homemade Lavender Extract

Once you have your homemade food grade lavender extract, the possibilities are endless. Start small, as the flavor can be potent.

What kind of lavender should I use for food grade extract?

When making food grade lavender extract, it’s crucial to use lavender varieties specifically designated as culinary or food grade. English Lavender (Lavandula angustifolia) is generally the best choice, particularly varieties like ‘Munstead,’ ‘Hidcote,’ or ‘Vera.’ These varieties are known for their sweet, floral aroma and flavor, making them ideal for culinary applications. Avoid using ornamental lavender varieties as they may have a higher camphor content, resulting in a less desirable, sometimes bitter, taste.

Always ensure the lavender you use is organically grown or sourced from a trusted supplier who doesn’t use pesticides or herbicides. This is important because these chemicals can be harmful if ingested and will certainly compromise the purity of your food grade extract. Thoroughly inspect the lavender flowers for any signs of insects or debris before starting the extraction process.

What type of alcohol is best for making lavender extract?

The best type of alcohol to use for making food grade lavender extract is a high-proof, neutral-flavored spirit. Vodka is the most common and readily available choice, with a proof of 80 (40% alcohol) or higher being recommended. Higher proof vodka extracts more flavor and aroma from the lavender, resulting in a more potent and flavorful extract. Avoid using flavored vodkas, as they will interfere with the pure lavender taste.

Alternatively, food grade ethanol (ethyl alcohol) can also be used, often available through specialty suppliers. This is generally a 190-proof (95% alcohol) spirit and needs to be carefully handled and measured. If using food grade ethanol, it may be necessary to dilute it slightly with distilled water to reach a suitable proof for extraction. Always ensure the alcohol source is explicitly labeled as food grade to ensure its safety for consumption.

How long should I let the lavender steep in the alcohol?

The optimal steeping time for lavender in alcohol typically ranges from four to six weeks. This period allows sufficient time for the alcohol to extract the essential oils and flavors from the lavender flowers. During this time, store the mixture in a cool, dark place away from direct sunlight, as light and heat can degrade the quality of the extract.

Gently shake the jar every few days to ensure even extraction. After the initial four to six weeks, you can sample the extract to determine if the flavor intensity is to your liking. If you desire a stronger lavender flavor, you can let it steep for an additional week or two, checking the flavor periodically until you achieve the desired strength.

How do I strain the lavender extract?

The straining process is crucial for removing the solid lavender flowers from the alcohol and obtaining a clear, usable extract. Begin by lining a fine-mesh sieve with several layers of cheesecloth or a coffee filter. This will help to remove any small particles and ensure a clean final product. Place the sieve over a clean glass jar or container.

Slowly pour the lavender-alcohol mixture through the lined sieve. Allow the liquid to drip through without pressing on the lavender flowers, as this can release bitter compounds. Once all the liquid has passed through, discard the spent lavender flowers. The resulting liquid in the jar is your lavender extract, ready to be used in your culinary creations.

How should I store my homemade lavender extract?

Proper storage is essential to preserve the quality and potency of your homemade lavender extract. Transfer the strained extract to a clean, airtight glass bottle, preferably a dark-colored bottle like amber or blue, as this helps to protect the extract from light degradation. Ensure the bottle is completely dry before pouring in the extract.

Store the bottle in a cool, dark place, such as a pantry or cupboard, away from direct sunlight and heat sources. The extract should remain stable and retain its flavor for several months, even up to a year, when stored properly. Check the aroma and flavor periodically to ensure it hasn’t degraded over time.

Can I use dried lavender instead of fresh?

Yes, you can use dried lavender flowers for making lavender extract, and in some cases, it may even be preferred. Dried lavender often has a more concentrated flavor than fresh lavender because the moisture content has been removed. When using dried lavender, you’ll typically need to use a smaller quantity compared to fresh lavender.

Ensure the dried lavender is culinary grade and has been properly stored to maintain its quality and prevent it from becoming stale. Check for a strong, pleasant aroma before using it. Follow the same extraction process as with fresh lavender, adjusting the quantity based on the intensity of the dried lavender’s scent.

What is the shelf life of homemade lavender extract?

Homemade lavender extract, when properly stored, typically has a shelf life of at least one year, and potentially longer. The high alcohol content acts as a preservative, preventing the growth of bacteria and molds. However, the flavor and aroma may gradually diminish over time, so it’s best to use it within a year for optimal results.

To maximize shelf life, always store the extract in a cool, dark place in an airtight, dark-colored glass bottle. Periodically check the extract for any changes in color, aroma, or clarity. If you notice any signs of spoilage, such as cloudiness or an off-putting odor, it’s best to discard the extract.
