The finest refined alcohol is used to assure the highest purity and maximum herbal absorption. Large doses of healing herbs are then added at different times during the preparation process. These herbs have been soaked in strong alcohol and water to extract the best flavours and smells. The mixture ripens for a long time, allowing all the herbs, and the main ingredient, wormwood (artemisa absinthium), to mix and mellow. The final product is distilled for a second time to give a 55 percent alcohol (110 proof) content and a hallucinogenic quality 6 times stronger than its UK competition. In addition to artemisa absinthium, the main herbal ingredients are anise and fennel, followed by camomile, coriander, mint, lemon balm and others, which are Sebor's secret.
