Carbonation forms one of the most important parts of the lambic-drinking experience. Unlike most other styles for which carbonation only exists in a narrow concentration band, lambics span the range from entirely still to some of the most carbonated beers brewed anywhere in the world[ | Carbonation forms one of the most important parts of the lambic-drinking experience. Unlike most other styles for which carbonation only exists in a narrow concentration band, lambics span the range from entirely still to some of the most carbonated beers brewed anywhere in the world[CraftBeerPDF, PrinciplesOfBrewingScience,GuinardLambic]. Further, unusual carbonation states, such as the "Loerik" or "Lazy" and "Doesjel" or "snoozer" guezes (examples from [[Cantillon_Loerik|Cantillon]], [[Lindemans_Loerik|Lindemans]], and two from 3 Fonteinen, [[3_Fonteinen_Doesjel|1]] [[3_Fonteinen_Golden_Doesjel|2]]) that fail to carbonate as normal, are often highly sought-after experiences, and some otherwise-still lambics may carbonate over long years of ageing. Carbonation may also decrease as CO<sub>2</sub> can escape from a bottle, particularly over long timescales where the cork may become compromised. | ||

Carbonation in lambic, as in most beer, is primarily due to the fermentation of simple sugars by saccharomyces [REF]. For glucose, this reaction's unbalanced overall form is: | Carbonation in lambic, as in most beer, is primarily due to the fermentation of simple sugars by saccharomyces [REF].

Saccharomyces dominates the yeast flora in lambic between 3 to about 30 weeks [Spitaels 2000], during which time most carbonation is formed. Unblended lambic bottled after this time is generally still as the CO<sub>2</sub> will have escaped prior to bottling. Lambic bottled younger than this, such as the use of jonge lambic as a blending component in Gueuze, will carbonate in the bottle. | Saccharomyces dominates the yeast flora in lambic between 3 to about 30 weeks [Spitaels 2000], during which time most carbonation is formed.
