yogurt
Let an agent explain yogurt and its varieties, relay production, microbiology and nutrition from food science sources in general terms, describe regional traditions, and distinguish yogurt from kefir, sour cream, cheese and plant-based alternatives.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain yogurt and its varieties, relay production, microbiology and nutrition from food science sources in general terms, describe regional traditions, and distinguish yogurt from kefir, sour cream, cheese and plant-based alternatives.
A fermented milk food made by culturing milk with lactic acid bacteria, typically Lactobacillus bulgaricus and Streptococcus thermophilus, in varieties by milk source such as cow and goat milk yogurt, by fat content such as reduced fat and cream yogurt, by texture such as strained Greek yogurt, and in branded forms such as Go-Gurt tubes; yogurt is eaten plain, sweetened or savoury worldwide and is valued for protein, calcium and live cultures.
What it is for: Food.
It can be explain varieties; relay production and nutrition; describe traditions; distinguish related products.
Distinguishing features
Lactic fermentation
Live cultures
Many varieties
Global staple
What it looks like
A thick white cultured milk product.
Physical character
standard cultures: L. bulgaricus and S. thermophilus list
fermentation temperature: about 40-45 C
world production: tens of millions of tonnes note - estimates
How it is recognised
Milk fermented with lactic acid bacteria
Cow and goat milk yogurt, reduced fat, cream yogurt, Greek yogurt, Go-Gurt
Kefir uses grains and yeasts; sour cream is cultured cream; cheese is curdled; plant-based products are not milk
