Leuconostoc mesenterodies and other cocci initiate fermentation and produce 0.7 to 1-.0 per cent lactic acid. Lactobacilli then multiply and continue the fermentation, increasing the acidity to as much as 2.4 per cent lactic acid. Acids, esters, and diacetyl give pleasant aromas and flavours. Fermentation requires three to four weeks 21 to 29"C.
