Orgeat is a sweet, non-alcoholic almond syrup flavored with orange flower water or rose water.
Orgeat gives tiki drinks and sours their almond-and-flower backbone; take it out of a Mai Tai and what is left is a rum sour. It separates in the bottle, so shake it before measuring. Check the label for two things. Real almonds make it an allergen a guest cannot see. Without orange flower water or rose water, it tastes of marzipan rather than orgeat.
Almond syrup
The closest swap, in the same amount. Many versions skip the floral note, so add a couple of drops of orange flower water per drink.
Almond-free orgeat
Made with flavorings, it swaps one for one. It is not a guarantee for a nut-allergic guest, so let them read the label.
Gives the almond with far less sugar and some alcohol. Use the same measure plus a little syrup, and expect a slightly stronger drink.
Rich syrup keeps the sweetness and body but loses the almond.
Sealed and commercial, months; homemade, a week or two refrigerated, because real orgeat is a nut emulsion and behaves like one. Separation is normal and shakes back in; a sour smell or a fizz is not.
