What is Skyr?
Skyr is a fermented fresh acid-curd soft cheese made from skim milk.
Skyr is made through a specific double fermentation process: skim milk + lactic acid bacteria
- Needed for good quality skyr: Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus, as in a classic yogurt
- Feed on the sugar content of milk (mainly lactose) yielding lactic acid lowering sugar content, lowering pH that coagulates milk proteins
- Lactobacilli produce aromatic diacetyl & acetaldehyde
- Occasional in skyr: Lactococcus spp & Lactobacillus casei
- Feed on sugars to yield organic acid
After fermentation, an intense straining gives it a dense texture, so thick that a spoon will stand up in it.
The cultural origins
Skyr is a central part of the Icelandic diet and culture, brought 900 years ago by the Vikings from Norway.
Originally made from ewe’s milk, it is produced from cow’s milk since the 20th century.
