Homemade yogurt has billions of high-quality probiotics with fresh, healthy ingredients.
Commercial yogurts have generic probiotics and are fermented fast, then cooled, sweetened, and shipped. When you ferment it yourself, you decide the milk, the strain, the time, and the flavors.

Consistent temperature is the key to quality fermentation.
Live cultures eat the lactose in milk and turn it into lactic acid. The acid thickens the milk and gives yogurt its tang. You need to hold it at the right temperature for the right amount of time.
This is why temperature accuracy matters. A yogurt maker that doesn't hold steady will not ferment as well.
-
Warm the milk, add the cultureAdd a spoonful of live yogurt or a starter into whole milk. Stir. Pour into the jars.
-
Set your temperature and timer100°F for 24 hours is the popular long-ferment method. For plain yogurt, run 8–10 hours at 110°F.

Let it workProbiotics grow, lactose becomes lactic acid, and the milk proteins transform into yogurt. You do nothing.

Common questions
Can I make L. reuteri yogurt in it?
Yes — that's what the 48-hour timer is for. Set it to 100°F and run a 24- or 36-hour ferment with your L. reuteri starter and half-and-half or whole milk. The Ultimate Probiotic Yogurt Maker holds a steady temperature the entire time.
How long does it take?
Five minutes of prep time. Everything else is waiting. A classic batch sets in 8–10 hours overnight; a long ferment for high probiotics runs 24–36 hours. Then we recommend refrigerating for four hours to firm up.
Does it work with non-dairy milk?
It does — the machine holds temperature regardless of what's in the jar. Coconut, cashew and soy all ferment well. Nut milks have no lactose for the culture to eat, so add a spoon of inulin or sugar as food for the cultures, and a thickener if you want it spoonable rather than pourable. The included 50-recipe eBook has non-dairy versions.
Is it dishwasher safe?
The glass jars, containers, and lids are all dishwasher safe — top rack for the lids. The base unit wipes clean with a damp cloth; don't submerge it.
What if my first batch doesn't set?
We include simple instructions and a free yogurt guide so your first batch comes out perfect. If you run into any trouble, our 5-star customer support team is ready to help.
What if it stops working?
We replace it. The unlimited lifetime warranty covers product failure for as long as you own it — no need to hunt down your receipt. Call, text, or email us, and our customer support team replaces it for free.
Why glass instead of plastic or metal?
Yogurt is acidic. Metal reacts with it, and plastic can leach into it. Glass does neither, which is why every jar and container that touches your yogurt is professional-grade glass. The casing is stainless steel; the base is BPA-free.
How much does it hold?
Two quarts (64 oz) with the two containers, or 1.5 quarts (48 oz) across eight 6-oz glass jars. Enough for a week of breakfasts for two.
Unlimited lifetime warranty on product failure, plus 30-day returns if it isn't for you. Real support by phone, text or email — no chatbot maze.
