It was mistakenly called fermentation because of the decarboxylation that occurs in the process. While we tend to think specific gravity measures the sugar in your … Continue reading The Impact of Malolactic Fermentation on Specific Gravity

The 3-Phases of Natural Fermentation

The phases of a wild/natural cider fermentation Apple juice fermented using its native microflora (yeast and bacteria) or what is sometimes called a wild fermentation, normally goes through three natural phases(1). Note that the length of each phase is impacted by temperature. The chart reflects a fermentation at temperatures of 14-22C (60-72F).

There is an often referenced but just as often confusing process in hard cider making called malolactic fermentation. You might see it abbreviated by the acronym MLF and sometimes referenced as LAB. In reality, it’s not actually a fermentation process at all but is a bacteria reaction that converts malic acid to lactic acid (1). … Continue reading Hard Cider Tip #28: Malolactic Fermentation
