Harvesting the spikes just as the lower flowers begin to open preserves the delicate balance of constituents, including linalool, linalyl acetate, and camphor, which define the therapeutic and olfactory character of the final oil. In a dedicated still, steam passes through the dried plant material, causing the oil glands to rupture and release their aromatic contents.

Once the flow slows to a trickle, you can shut off the heat and allow the apparatus to cool before separating the oil from the hydrosol. This method uses a food-grade hexane or ethanol solvent to dissolve the aromatic molecules from the dried lavender, creating a concrete that retains the plant's full character.
The distillation itself usually requires one to three hours, during which time the oil droplets gradually accumulate in the collection vessel. Electric stills with precise temperature controls offer convenience and safety for small-batch production, while stovetop models provide a more hands-on approach for experienced hobbyists.

It is crucial to ensure all connections are airtight to prevent the loss of precious aromatic molecules and to maintain consistent pressure throughout the distillation cycle. Understanding the botanical profile of Lavandula angustifolia, the specific chemistry of the oil, and the practical methods available allows you to select the process that aligns with your goals and equipment.
