What You Need to Know
Lactic acid bacteria such as Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus hydrolyze lactose to lactic acid, dropping the milk pH to 4.5–4.8 and inducing casein gelation. Proteolytic enzymes from these microbes release peptides that contribute to the creamy mouthfeel and nuanced flavor, while the calabash’s micro‑aerophilic environment and minor tannin content suppress spoilage organisms.
