Open-source cola

Recipe

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.{{Cite web |access-date=2012-09-19 |archive-date=2017-10-18 |archive-url=https://web.archive.org/web/20171018153951/http://cube-cola.org/index.php?route=product%2Fcategory&path=20 |url-status=dead

Coca-Cola's own flavouring syrup is known in-house as "Merchandise 7X", which is cross-referenced in the open recipes.

A typical recipe is based on eight essential oils, listed here in approximate order of decreasing volume:

• orange oil
• lime oil
• cassia oil
• lemon oil
• nutmeg oil
• coriander oil
• lavender oil
• neroli oil

These are based on the "Pemberton formula."{{Cite book |orig-year=1993 |access-date=19 September 2012 |archive-url=https://web.archive.org/web/20130719221553/http://news.sciencemag.org/sciencenow/2011/05/scienceshot-how-natural-is-your.html?rss=1 |archive-date=19 July 2013 |url-status=dead

The use of lavender oil is considered something of a personal taste. Neroli is frequently omitted altogether, owing to its high cost and relatively small contribution to the overall flavour. Neroli alone may represent a third of the concentrate ingredients' cost.{{Cite web

As well as the basic list of flavouring ingredients, there are other ingredients such as food grade 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 emulsifying the concentrate.

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, halal, or similar rules would require it.
