A fifth stage of fermentation in the bottle after most brettanomyces fermentation is complete may exist, however research towards the long-term aging of lambic is scant. The various stages of fermentation have a significant degree of overlap with one another as the yeast and bacterial populations live alongside one another, and the times at which they begin and end can vary by up to several months [2].

The microbes present in lambic may come from a variety of sources in the brewhouse and the surrounding environment, including the surrounding air, the walls and ceilings of the brewhouse, and the wooden barrels the beer is kept in [2]. The organisms in lambic are present in different parts of the environment and it is likely that the organisms responsible for lambic come from a number of different places.
