Unlike traditional oude gueze which consists of a blend of one-, two-, and three-year lambic, Girardin Black is a blend of twelve-, eighteen-, and twenty-four-month lambic. According to Paul Girardin, he "blend[s] lambics of 12, 18, and 24 months to make the Oude Gueuze. The 2-year-old lambic is for complexity, light acidity and maturity; the year-old version is to spark a refermentation, and the 18-month-old lambic is used to balance the 1- and 2 year-old versions."<ref name=ASNGirardin)>Chuck Cook, Exclusive, Self-Sufficient, Independent - Girardin Survives, Ale Street News, 2009, http://www.alestreetnews.com/travel/321-exclusive-self-sufficient-independent-girardin-survives.html</ref>
Though there is no complete bottle log for this gueuze. Girardin Black, as it is colloquially referred to, dates back to at least the 1990's. The bottles are not dated; however, beginning in the mid 2000's the corks began to show bottling batch numbers. For example ''EFx2012Ax2013'' may be read as a 2012 2013 batch. However, this should only be used as a reference and may not necessarily indicate the bottling yearas certain batches have arrived on store shelves prior to the year marked (e.g., Ax2013 arrived on store shelves in late-2012).
Girardin Black is available around the world, but it is only available in 37,5cl bottles in the United States. Both 75cl and 37,5cl bottles can be ordered from various Belgian webshops.
