Alcohol shock is a harsh, sharp or solvent-like flavour that can occur when wine or spirits are added to a dish and the alcohol has not had enough time to integrate with the other ingredients. It is a sensory description rather than a formal chemical reaction. The intensity depends on the type and amount of alcohol, cooking method, time and the rest of the recipe.
Adding a concentrated spirit or wine late in cooking can leave a prominent alcoholic aroma and taste. A large addition may also disturb the balance of acidity, sweetness and seasoning. Simply bringing the liquid to a boil for a few seconds does not guarantee that the alcohol has evaporated.
After searing meat, a chef may deglaze the pan with a measured amount of wine or cognac. The liquid is simmered or reduced to integrate its flavour and concentrate the fond before stock, cream or butter is added. If a large amount of spirit is added immediately before service, the finished sauce may taste harsh and unbalanced.
A sauce can taste sharp because of excess acidity, raw alcohol or both. Alcohol has a distinctive warming aroma and taste, while acidity produces a sour sensation. Taste and adjust the appropriate component rather than automatically adding sugar or more stock.
Chef’s tip: taste the sauce after the alcohol has cooked with the other ingredients and again after the final reduction. A mellow flavour does not mean all alcohol has evaporated.
