20-25 days), low temperature (starts at 7-8 "C) process, but eventually the yeast concentration reaches 3 or 4 x lo8 cells ml-', and the fermentation rate increases, as does the temperature (15-1 6 "C). In commercial sak&brewing, the natural acidification of the mash by lactobacilli is usually replaced by addition of lactic acid, something which allows the fermentation to proceed at elevated temperatures in a shorter period of time, thus truncating brewing time. Another commercial "short cut" is to add an inoculum of yeast (called moto).
When viewed from a modern maltsters’ and brewers’ point of view, none of the other cereals is as “user-friendly” as barley. This can be attributed to the lack of a husk around the seed coat, and to other variables, such as the nature and amount of protein surrounding the starch granules, the nature of the starch in the granules, and the composition of the endosperm cell walls. Wheat (Tritium aestivum), for example, which is probably the most extensively grown crop, worldwide, has a “naked” cereal grain (no The Beginnings 15 husk) and so, after milling and mixing with hot water, does not contribute effectively to the provision of a filter medium in the mash-tun after mashing.
Whatever the recipe, fermentation of chicha from manioc is basically induced either by masticating cassava and letting the salivary enzymes do their work, or by allowing a mould culture to develop. In the regions conquered by the Incas, chicha is made from maize, their most important crop in terms of quantity and prestige. The beverage is prepared in a variety of ways, but the two major variants in this maize beer preparation involve the source of the diastase. In much of the Americas, a common source of diastase is saliva (as with chicha from manioc).
