Extractions

Mushrooms are structurally different from most herbs and plant materials you might work with. Their cell walls are built from chitin, the same indigestible material found in crustacean shells. Chitin does not dissolve in water, and it resists alcohol as well. For any meaningful mushroom extraction to occur, the cell wall needs to be broken down before the solvent can reach what is inside, whether that means heat, mechanical grinding, or a combination of both. A mushroom that has been soaked in vodka, strained into a dark bottle, and sold as a tincture has not been properly extracted at all. T

High-proof food-grade ethanol at 190 proof covers the alcohol-soluble side efficiently. At 95% concentration, it dissolves triterpenes like the ganoderic acids in Reishi and hericenones in Lion’s Mane without demanding extended soak times. The 5% water content in 190 proof also provides partial access to water-soluble compounds, though a dedicated hot water extraction step is needed to fully reach the beta-glucans. Lower-proof spirits, the 40% vodka that beginners typically start with, are accessible but severely limited.

The species you start with sets the ceiling for what you can produce. Lion’s Mane, Reishi, Chaga, and Cordyceps are the most widely used in medicinal mushroom extraction, and each carries a distinct compound profile that requires the method to be adapted accordingly. Reishi, for example, is dense with triterpenes that need alcohol at 190 proof or above to extract efficiently. Lion’s Mane holds polysaccharides that require hot water to become properly bioavailable. A tincture using only one solvent for either species extracts selectively, not fully.

The phrase food-grade alcohol appears on bottles sold to herbalists, distillers, home producers, and professional manufacturers across every scale of operation. Most buyers assume the label means it’s safe. That assumption is usually correct, but the label alone is not the complete picture. Understanding what food grade alcohol actually requires, and where those requirements stop, changes how you evaluate products and what you ask for before buying.Ethyl alcohol and ethanol describe the same molecule:
