A Midwestern ice cream nobody agrees on, built on a flavor base whose formula has never been published.
What flavor is Blue Moon ice cream?
Blue Moon tastes mostly of sweet citrus over vanilla and marshmallow, often with an almond or raspberry edge, and many people compare it to Froot Loops milk. The company that owns the name calls it citrus and has never published the formula.
Flavor profile
- Family
- Candy
- Character
- Sweet, fruity and creamy; citrus over vanilla-marshmallow, often with almond or raspberry notes
- Key components
- Not published. Citrus, vanilla and a benzaldehyde-type almond note match what people describe
- Impact
- Medium
- Typical dosage
- Set by the base supplier; ice cream runs higher than drinks because cold suppresses flavor
- Heat stability
- Not usually a concern; the flavor goes into pasteurized mix before freezing
- pH stability
- Not a concern at ice cream pH
- Natural availability
- Blue moon-type flavors are sold by several flavor houses; the profile is constructed
Blue Moon is a regional ice cream. Weber Flavors, the Illinois company that owns the trademark, says demand is highest in Wisconsin, Michigan and Illinois, with smaller pockets elsewhere.1 Outside the Upper Midwest, most people have never seen it.
What people say it tastes like
Ask ten people and you get ten answers. These are the common ones.
| Claim | Who says it | What it suggests |
|---|---|---|
| Citrus | Weber Flavors, which sells the base | The only description from the owner |
| Froot Loops or cereal milk | Customers, and at least one Wisconsin creamery about its own version | Several fruit and citrus notes over vanilla |
| Marshmallow or vanilla | Customers | Vanilla carrying the sweetness in the dairy base |
| Almond or marzipan | Customers and food writers | A benzaldehyde-type note |
| Raspberry or cotton candy | Customers | Candy-style fruit esters |
Weber has described it simply as a citrus flavor and will not say what is in it.2 The cereal comparison is the most useful clue for a developer. It points to a blend of fruit and citrus notes over a creamy base, not to any single fruit.
A rumor says the original used castoreum, an extract from beaver glands. Nobody has produced evidence for it.
Where it came from is disputed
No one has proven who invented it.
- Milwaukee. The best-known story credits Bill "Doc" Sidon, a chemist at Petran Products, in the 1950s. His daughter has said he never claimed it.
- The paperwork problem. Petran's 1970s trademark filing claimed use of the name since at least 1939, before Sidon is said to have arrived. A 1931 Ohio dairy ad already listed "blue moon" as a flavor, though nobody can say what it tasted like.1
- Michigan. Sherman's in South Haven and House of Flavors in Ludington are both linked to it. Sherman's has said it bought its Blue Moon flavoring from an outside supplier.
What is settled: Weber bought the Blue Moon trademark from Petran in 1982.2
Blue Moon is also usually the blue part of Superman ice cream, which carries its own unproven origin story.
Building a blue moon-type ice cream
Check the name before the carton. Weber holds the trademark for Blue Moon ice cream flavoring. If your base comes from Weber, ask what naming rights come with it. If it comes from anyone else, get advice before "Blue Moon" goes on the pack.
Brief by description, not by name. Tell the flavor house which of the claims above your customers expect. A citrus-forward version and a marzipan-forward version are each "authentic" to someone. Loyalty is local: people who grew up on one dairy's version often reject another's.
Cold hides flavor. Ice cream is eaten cold enough to dull aroma, so the mix needs more flavor than it seems to at room temperature. Judge it frozen. The dairy hub covers why. Citrus is the most fragile part of the profile, so taste it again at the end of shelf life.
The almond note needs a light hand. Benzaldehyde, the compound behind amaretto, turns medicinal fast. In a sweet, creamy base it should read as a hint, not a flavor.
The blue does a lot of the work. Weber sells its base with and without color, and the colored version sells far better.1 Most cartons use Blue 1. If you move to a natural blue, check the shade against the cream-colored base, which can push a blue toward teal. As with blue raspberry, a version that is not blue reads as a different product.
The honest limit: there is no reference sample. You can match one dairy's Blue Moon closely. You cannot make one that every Blue Moon fan will accept.
