Vacuum distillation is transforming British spirit production by preserving delicate botanical flavors through low-temperature extraction. Here's why this method stands out:
- Preserves Aromatics: Lower boiling points protect heat-sensitive botanicals.
- Precise Flavor Control: Ensures consistency and depth in spirit profiles.
- Energy Efficiency: Uses less energy compared to traditional distillation.
- Hybrid Techniques: Combines with traditional methods for balanced results.
Producers like Asterley Bros in South London are leading the way, using vacuum distillation to craft premium vermouths and amaros with intricate flavor profiles. This approach is shaping the future of British spirits by unlocking new possibilities for botanical extraction and flavor development.
Vacuum Distillation & The Rotavap
Vacuum Distillation Process
Vacuum distillation works by lowering boiling points, allowing botanicals to be distilled at cooler temperatures. This gentle approach helps protect delicate aromatics that might otherwise be damaged by heat. By reducing pressure, the process achieves distillation at much lower temperatures than traditional methods.
This lower-temperature operation is key to preserving volatile aromatics and fragile botanical flavors, as it minimizes the risk of thermal damage. These controlled conditions are central to modern botanical extraction techniques, especially in the production of British spirits.
Producers value this method for its ability to retain complex flavor compounds, especially when working with sensitive botanicals or ingredients. The result is a careful extraction process where each botanical's unique character is preserved, ensuring the final spirit reflects the quality and authenticity that British spirits are known for.
Current Uses in British Spirits
Botanical Extraction Methods
Producers of British spirits use vacuum distillation to extract flavors from herbs, spices, and fruits at lower temperatures. This method helps maintain the natural essence of ingredients, making it ideal for crafting intricate botanical spirits like vermouth and aperitifs. It’s a key technique for achieving subtle and layered flavor profiles.
British Producer Examples
Asterley Bros London, based in South London, showcases a commitment to handcrafted botanical spirits. Their lineup - including SCHOFIELD'S Dry Vermouth, ESTATE Sweet Vermouth, and Britannica London Fernet - highlights the importance of precision in botanical extraction to preserve delicate flavors.
Combined Distillation Approaches
Many British producers combine vacuum distillation with traditional methods. This hybrid approach allows them to use vacuum techniques for fragile aromatics while leveraging conventional methods for stronger botanicals. The result is a balance of complexity and consistency, enabling both creative new interpretations and the retention of classic flavor profiles.

Benefits for Spirit Production
Flavor Control Methods
Vacuum distillation takes flavor control to the next level by enabling precise extraction at lower temperatures. This method safeguards the unique characteristics of each botanical, ensuring the final spirit retains its complex and consistent flavor profile. It’s a game-changer for crafting intricate botanical blends while maintaining a high standard of quality.
Asterley Bros London showcases this approach in their SCHOFIELD'S Dry Vermouth. By using vacuum distillation, they preserve the distinct essence of each botanical, resulting in a balanced and refined flavor. This technique allows producers to consistently deliver exceptional quality while experimenting with new flavor combinations in their craft spirits.
Future Developments
New Applications
Vacuum distillation is opening up fresh possibilities for British spirits. By preserving delicate aromatics, this method is helping producers create more intricate flavor profiles. For instance, Asterley Bros London uses vacuum distillation to craft premium spirits with unique botanical combinations. This precise approach to extracting and maintaining delicate compounds is unlocking new potential in flavor creation.
Flavour Development
Thanks to its lower-temperature operation, vacuum distillation is making it possible to capture botanical notes that were previously out of reach. British producers are now experimenting with layering multiple botanical extractions, which could lead to:
- Preserving temperature-sensitive compounds
- Extracting subtle, nuanced botanical notes
- Achieving greater control over the overall flavor profile
Industry Standards
While there are no formal standards yet for using vacuum distillation in spirit production, British producers are experimenting and pushing boundaries. This method’s ability to handle complex botanical extractions is already shaping new practices. As the technique continues to evolve, it’s likely to influence future production protocols and refine how botanical extractions are approached.
