I had never seen it spelled like that. After doing some digging I found a few really old references in English that did use that or similar spellings. I’ve always spelled it kumis but it looks like that’s the more modern or standard spelling based on " кумыс" and coumiss or koumiss is an older variant. Older still is “cosmos” which is what some English bloke in the 13th century called it.
Welp, of the somethings new, that’s the one I learned today.
I’ve seen a variety of spellings, which is typical for a term adopted from a foreign language. My daughter-in-law is Turkish; they say kimiz. Mongols call it something entirely different.
I don’t have any actual mare’s milk. I make a faux mare’s milk from cow’s milk by adding lactose.
My wife tried it without heat because that’s what the recipe said. I look forward to trying with heat.
Right, I’m not going to sterilize the 'chokes, but I may try to get 1-2 bacterial species to dominate. My AI says, “Some LAB strains, particularly those belonging to the genus Lactobacillus (e.g., Lactobacillus paracasei, Lactobacillus plantarum), have been shown to metabolize inulin. They break down inulin into simpler sugars (fructose) that can be further fermented into lactic acid and other metabolites.” I’ve got commercial products prepared for fermentation of lactic acid in milk (e.g., for koumiss, cheese) that include the named strains.
In my own attempts, taste is great – but I like sour. I never tasted what I’d consider perceptible ethanol though there is probably 1-2%.
The biggest challenge is texture. As I’ve learned, the coagulation of milk depends on pH. Peak coagulation comes in the mid 4’s, below the more neutral pH of milk but above the acidic pH of the final product. As the product ferments – milk becomes koumiss – there’s progressively more lactic acid so pH drops. To get a smooth texture, it seems that I need the fermentation to proceed quickly so that the pH drops rapidly through the zone where coagulation is fastest. It seems that if the fermentation is fast, then the curd is very smooth, it tends to resist quick separation from the whey, so the product is drinkable.
It seems we’re having a miscommunication. For fermentation you don’t use heat. I referenced two different processing methods. Acid + heat is the fast, ready in thirty minutes method. Fermentation is the ready in a couple weeks method.
I plead guilty. My 1st sentence was about the (quick) heat + acid treatment. The next paragraph was meant to be responsive to your comment about the (slow) fermentation process. Sorry for the confusion.
