A SWEETENED/FLAVORED VODKA ABV @ 20 °C = 35.0% ABWt @ 20 °C = 27.6% {see Eq. 1} 11.6°P = real extract °P = degrees Plato, g/100g or % by weight
0.05 = protein % by weight 0.00 = ash % by weight 1.00105 = SG of the spirit 44.36 = 1.5 US fl. oz. in mL
Calories per 100 grams of spirit = 6.9 * (27.6) + 4 * (11.6 - 0.05 – ^0.00) = 236.6 Calories per 1.5 fl. oz. (44.36 mL spirit) = 236.6 * (44.36 * 1.00105/100) = 105.1 [105.0 Calories or kcal.]
tradition
The more sugars in spirits the greater the calories — quite significantly more for some modern-day spirits with 20-35 Plato sugar content (25-30 grams sugar per 100 grams of spirit!) Certain honey-flavored whiskey brands and very often cream-based liqueurs

As noted above – the author points out that solids determination methods for wine and spirits as presented by the TTB are not, according to theory, correct or the most acceptable means to an end. The methods rely on computations involving sample and alcohol specific gravities to determine the real extract gravity (and subsequently the solids content or extract value in mass terms). Such an approach only works within certain limits, as addressed elsewhere (Spedding, 2016) or as might be discussed upon consultation with the author. In addition, sugars, when present in high concentration, lead us to some erroneous alcohol readings; this is based on other chemical properties of the sugars in an ethanol-water solvent system. This issue was addressed, and resolved, by a graduate student from
