what type of liquor is in egg nog
Eggnog There are variations in ingredients in different recipes. Traditional eggnog has a significant fat content, due to the use of cream, and a high sugar content. Ingredients vary significantly between different recipes. Alcohol used in different national and regional versions of eggnog include brandy, cognac, bourbon, whiskey, sherry, rum and grain alcohol. Canadian chef Heidi Fink states that one of the reasons people are making less homemade eggnog is that the beverage is expensive to make, due to its use of substantial quantities of cream, eggs, and spirits.[26] Concerns about the safety of raw eggs may be another reason for the decline in homemade eggnog making.[26]
Azeotrope Many azeotropic mixtures of pairs of compounds are known,[5] and many azeotropes of three or more compounds are also known.[6] In such a case it is not possible to separate the components by fractional distillation. There are two types of azeotropes: minimum boiling azeotrope and maximum boiling azeotrope. A solution that shows greater positive deviation from Raoult's law forms a minimum boiling azeotrope at a specific composition. For example, an ethanol-water mixture (obtained by fermentation of sugars) on fractional distillation yields a solution containing approximately 95% by volume of ethanol. Once this composition has been achieved, the liquid and vapour have the same composition, and no further separation occurs. A solution that shows large negative deviation from Raoult's law forms a maximum boiling azeotrope at a specific composition. Nitric acid and water is an example of this class of azeotrope. This azeotrope has an approximate composition of 68% nitric acid and 32% water by mass, with a boiling point of 393.5 K (120.4 °C).
