About the Blue Moon

A gin highball, dry Martini and ruby bitter gin cocktail in a botanical bar.

Two violet liqueurs

Crème de violette was effectively unavailable in the United States for decades, which is why so many mid-century books quietly drop it or hand the job to crème Yvette. It came back in the mid-2000s and there are now several bottlings. Giffard leans candied and sweet, Rothman & Winter is drier and more clearly floral, and the two are not interchangeable at this dose.

Measure it, don't pour it. Fifteen milliliters is already at the top of the sensible range, and past that the drink turns into soap and parma violets. If you want the color without the perfume, drop to 10 ml and add 5 ml of simple syrup so the sour still balances against the lemon.

Common questions

Blue Moon FAQ

How is this different from an Aviation?

Same violet-and-gin idea, minus the maraschino. An Aviation splits its sweetness between maraschino and violette, so it lands drier and stonier. Here the violette carries the sugar on its own, which pushes the floral side forward and rounds off the finish.

Pink instead of blue. What did I do wrong?

Nothing. Violet pigment shifts toward pink as acidity rises, so a generous pour of lemon pulls the color out of lavender and into rose. It tastes the same either way. Drop the juice to 12 ml if the color is what you're after.

Can I use crème Yvette in its place?

Yes, and older printings of this drink actually call for it. Yvette carries berry and vanilla alongside the violet, so the result comes out sweeter and less perfumed. Pull it back to about 12 ml, since it sits heavier on the tongue than a straight violette.

My violette has turned dull brown in the bottle. Still usable?

Almost certainly. Violet color fades with light and time while the flavor holds on, so a browned bottle mostly costs you the lavender tint. Keep it in a cupboard rather than on a windowsill, and buy the smallest size you can find.

What ingredients are in a Blue Moon?

A classic Blue Moon calls for 60 ml (2 oz) Gin, 15 ml (0.5 oz) Crème de violette, 15 ml (0.5 oz) Fresh lemon juice. That single-serve spec scales cleanly — the recipe above converts it to oz and multiplies it for 2–4 drinks.

How strong is a Blue Moon?

A standard Blue Moon is roughly 30% ABV once mixed (before ice melt softens it further). That makes it spirit-forward — closer to a Martini than to a beer, so sip it slowly.

Is a Blue Moon shaken or stirred?

A Blue Moon is shaken — the rule of thumb is to shake anything with citrus juice. About 13 seconds with plenty of ice chills and dilutes it correctly.
