Every December the same thing happens: someone doubles Grandma's eggnog recipe by feel, runs out of cream, and the party drinks store-bought anyway. This calculator scales a classic eight-serving base - six eggs, two cups of milk, one cup of cream, half a cup of sugar - to any headcount from 4 to 24, and prices the batch so you know what the pitcher actually costs before the party does.
Bottom line: eggnog for 16 guests means a dozen eggs, four cups of milk, two cups of cream and a cup of sugar - about $7 of ingredients, 43 cents a glass virgin; add the traditional 1.5 cups of bourbon-or-brandy per base batch and the same party runs $24, $1.50 a glass. The alcohol is 70% of the budget, which is exactly why the spiked bowl empties first and the host eats the difference.
The honest part: classic eggnog is a raw-egg custard, and raw eggs carry salmonella risk the FDA would rather you not gamble on for a crowd - the safe routes are a cooked base (heat the custard to 160 F, chill, then finish) or pasteurized shell eggs (they say so on the carton). Store-bought sits at $4-10 a quart and pours $1.25-2.50 a glass, so homemade is cheaper mostly when you skip the bourbon - the flavor, however, is not on the same scoreboard.
How to use
- Enter your guest count and how many glasses each will realistically have (two is the honest average).
- Read the scaled ingredient list and the batch cost, virgin or spiked at the classic 1.5-cups-per-batch ratio.
- Choose your egg route - cooked base to 160 F or pasteurized eggs - before you crack anything for a crowd.
Frequently asked questions
How much eggnog do I need per guest?
Plan on two 6-ounce servings per adult for a party where eggnog is the feature - about 1.5 cups per person - and one serving if it is just an option on a full bar. Twelve guests at two glasses each is nine cups, which is one and a half base batches (a base batch of 8 servings pours exactly half a gallon). The calculator's guest count assumes two glasses; halve the ingredient list if your crowd drinks like tasters.
Is homemade eggnog safe with raw eggs?
The classic recipe is a raw-egg custard, and the FDA's egg-safety guidance treats raw shell eggs as a salmonella risk worth managing - about 1 in 20,000 eggs carries it. Three honest routes: cook the base to 160 F (eggs, sugar and half the milk, stirred to 160, then chilled - the texture barely changes and the safety question ends), buy pasteurized shell eggs, or use a carton of pasteurized egg product. Serving vulnerable guests - pregnant, elderly, immune-compromised - the cooked base is not optional.
Why is spiked eggnog so much more expensive per glass?
Alcohol arithmetic: the classic ratio is about 1.5 cups of bourbon, brandy or rum per 8-serving batch, and a $18 bottle holds roughly 3 cups - so the booze alone adds $9 a batch, $1.07 a glass, on top of the 43-cent base. The spiked glass at $1.50 still beats the bar, but it is 3.5 times the virgin cost, which is why the smart party pours the virgin bowl big and offers the bottle alongside - guests self-segregate and the budget survives.
Can I make eggnog ahead, and how long does it keep?
Yes - and aged eggnog is the connoisseur move: a cooked, well-refrigerated base (below 40 F) actually mellows over days as the alcohol and cream integrate. FDA cold-storage guidance gives homemade egg dishes 3-4 days; spiked versions buy a little more time because alcohol is preservative, and avid agers push a bourbon-heavy batch two weeks in a sealed jar at their own (informed) risk. Anything unpasteurized served to guests should still be made inside the 3-4 day window - the flavor peak and the safety window conveniently overlap around day two.
