'''Open-source cola''' is any [cola](/source/cola) soft drink produced according to a published and shareable [recipe](/source/recipe). Unlike the secretive [Coca-Cola formula](/source/Coca-Cola_formula), the recipes are openly published and their re-use is encouraged.<ref name="OpenCola formula" >{{Cite web

The colas are produced as a flavour concentrate or syrup that is then mixed with bulk ingredients to produce the drink. Completed flavour concentrates are sold by some of the open cola producers.<ref>{{Cite web

  }}</ref> The bulk ingredients include those such as sweeteners ([sugar](/source/sugar) or [artificial](/source/artificial_sweetener)), [caffeine](/source/caffeine) and the source of acidity, [phosphoric](/source/phosphoric_acid) or [citric acid](/source/citric_acid) as these are added later, after the flavour blending stage, sugar and caffeine levels per batch can be tailored to a market's particular taste.

Coca-Cola's own flavouring syrup is known in-house as "Merchandise 7X", which is cross-referenced in the open recipes.<ref name="OpenCola recipe" />

A typical recipe is based on eight [essential oil](/source/essential_oil)s, listed here in approximate order of decreasing volume:<ref name="OpenCola recipe" />
* [orange oil](/source/orange_oil)
* [lime](/source/lime_(fruit)) oil
* [cassia](/source/Cinnamomum_aromaticum) oil
* [lemon](/source/lemon) oil
* [nutmeg](/source/nutmeg) oil
* [coriander](/source/coriander) oil
* [lavender](/source/lavender) oil
* [neroli](/source/neroli) oil

These are based on the "[Pemberton](/source/John_Pemberton) formula."<ref name="Pendergrast" >{{Cite book

One ingredient that is missing from these recipes is the eponymous [kola nut](/source/kola_nut),<ref name="Meyers" >{{Cite journal

The use of lavender oil is considered something of a personal taste.{{according to whom|date=July 2016}} Neroli is frequently omitted altogether, owing to its high cost and relatively small contribution to the overall flavour.<ref name="Cube-Cola, recipe" /> Neroli alone may represent a third of the concentrate ingredients' cost.<ref name="Cube-Cola, finance" >{{Cite web

As well as the basic list of flavouring ingredients, there are other ingredients such as food grade [gum arabic](/source/gum_arabic) and a considerable degree of "art" in its manufacture. The precise quality and sourcing of ingredients makes an appreciable difference, particularly in the process of [emulsify](/source/emulsify)ing the concentrate.<ref name="Cube-Cola, recipe" /> 

Small quantities of alcohol may be used to facilitate this process; as an open recipe, this is under the control of the manufacturer who may avoid such ingredients if [prohibition](/source/prohibition), [halal](/source/halal), or similar rules would require it.
