The standard hummingbird feeder recipe is one part refined white sugar to four parts water. Audubon and Cornell both publish this 1:4 ratio. You do not need red dye, honey, brown sugar, molasses or artificial sweetener.
The recipe scales directly
1 cup water → 1/4 cup sugar
2 cups water → 1/2 cup sugar
4 cups water → 1 cup sugar
8 cups water → 2 cups sugar
The ratio stays the same: divide the water amount by four to get the sugar amount by volume.
Use plain refined white sugar
Audubon recommends refined white sugar and advises against honey, molasses, brown sugar and artificial sweeteners. Cornell likewise recommends ordinary table sugar and says food coloring is unnecessary.
The feeder itself can provide the visual attraction. Red plastic parts or nearby flowers are enough; the liquid does not need to be red.
Do you have to boil hummingbird nectar?
You need the sugar fully dissolved in clean water. Audubon recommends bringing the mixture to a boil and cooling it before use; Cornell notes that small fresh batches can be made without boiling, while boiling is useful when preparing larger batches for refrigeration.
The practical priority is not the argument over boiling. It is using the correct ingredients, keeping the solution fresh and maintaining a clean feeder.
Make only as much as you can keep fresh
Large batches are convenient only if the extra solution is stored properly. Refrigerate unused prepared nectar and do not keep refilling a feeder with old solution simply because some remains.
Heat speeds spoilage. The next step after mixing the recipe is therefore maintenance, not tweaking the sugar concentration. See the hummingbird feeder cleaning guide for a practical schedule.
Do not make the mixture stronger to attract more birds
The prepared OwlRatings workflow uses the established 1:4 recipe as the normal feeder standard instead of encouraging improvised stronger solutions. If hummingbirds are not visiting, look first at feeder placement, local flowers, season, territorial behavior and cleanliness rather than changing the basic recipe.
A feeder is supplemental habitat
Audubon recommends native flowering plants as an important natural food source alongside a well-maintained feeder. A clean sugar-water feeder can supplement the yard; it should not replace habitat.
The main takeaway
Use one part white sugar to four parts water, dissolve it fully, cool before filling, refrigerate extra solution and skip red dye and alternative sweeteners. The recipe is simple on purpose; most feeder problems are maintenance problems, not recipe problems.
