Description

Mark Stone, Asa Stone, and Adam Harbaugh: Lambic at the Crossroads of Climate Change and Cultural Practice: The Impacts of Climate Change on Lambic Production

Inoculation of lambic and other spontaneously fermented beers is known to be highly sensitive to ambient conditions surrounding the koelschip. One of the most important environmental variables impacting the character of the spontaneous inoculation is the overnight low temperature. For example, traditional lambic brewing methods require nighttime low temperatures between approximately -8°C and +8°C to promote inoculation from desirable wild microbial flora. In the Zenne Valley, the average overnight temperature has increased by nearly 2°C over the past 65 years. As a result, the number of nights in a brewing season with low temperatures in the desired range has dropped dramatically from around 155 days in the 1950s to 130 days currently. In this talk, we will discuss the ramifications of these changing climatic conditions on lambic production in the Zenne Valley including projections through the end of the 21st Century and also provide context for these changes with respect to cultural heritage, practice, and tradition.
