As an expert sommelier and brewer, I can provide you with a detailed answer to your question about the number of calories in a shot of 90 proof coconut rum.
To start, let's break down what exactly 90 proof means. In the United States, the proof of an alcoholic beverage is twice the percentage of alcohol by volume (ABV). So, a 90 proof rum would have an ABV of 45%.
Now, let's talk about calories. Alcohol contains empty calories, meaning they provide energy but lack essential nutrients. In fact, alcohol is the second-highest calorie per gram substance after fat, with 7 calories per gram. This is higher than carbohydrates and protein, which both contain 4 calories per gram.
Considering the ABV of 45% in the Captain Morgan Parrot Bay 90 Proof Coconut Rum, we can estimate the number of calories in a shot. A standard shot in the US is 1.5 fluid ounces, which is approximately 44 milliliters.
To calculate the calories in a shot of this rum, we need to know the specific gravity of the alcohol. The specific gravity determines the density and therefore the calorie content. Unfortunately, specific gravity values are not commonly provided for individual alcoholic beverages.
However, we can estimate the number of calories by assuming that the specific gravity of the rum is similar to that of other spirits. Generally, spirits have a specific gravity of around 0.79 to 0.85. Let's use the average value of 0.82 for our calculation.
First, we need to convert the volume of the shot to milliliters. Since 1 fluid ounce is approximately 29.57 milliliters, a 1.5 fluid ounce shot would be approximately 44 milliliters.
Next, we multiply the volume in milliliters (44 ml) by the specific gravity (0.82) to get the weight in grams. This gives us a weight of around 36.08 grams.
Now, we multiply the weight in grams by the calorie content of alcohol (7 calories per gram) to get the total number of calories. In this case, it would be approximately 252.56 calories.
Therefore, a shot of Captain Morgan Parrot Bay 90 Proof Coconut Rum would contain approximately 252.56 calories.
It's worth mentioning that these calculations are estimates, as the specific gravity of the rum may vary slightly and affect the calorie content. Additionally, different brands and variations of coconut rum may have slightly different calorie counts.
It's important to be mindful of the calorie content in alcoholic beverages, especially if you are watching your calorie intake. Drinking in moderation is key, and it's always a good idea to enjoy alcohol responsibly and consider the overall balance of your diet.
I hope this detailed explanation helps you understand the approximate calorie content in a shot of 90 proof coconut rum. If you have any more questions, feel free to ask!
