Mesophilic Yogurt: A Recipe for Everyday Nourishment

There’s a subtle magic in leaving a jar of milk on your countertop and waking up to yogurt.

Mesophilic yogurt is a cooler-temperature ferment that thrives between 70°F and 80°F, making it a low-effort way to keep a nutritious batch of yogurt in your kitchen without special equipment. With a few spoonfuls of active culture in a jar of milk on your kitchen counter, you can begin a gentle ritual that invites microbial life into your daily rhythm.

Mesophilic yogurt is a smooth, drinkable or spoonable yogurt, more delicate than store-bought, but rich in flavor. It has been tended in Scandinavian kitchens for generations and is simple enough to make while the kettle boils or your porridge simmers. It’s the perfect yogurt for the busy fermenter looking to bring a little slowness into your life.

Equipment

• 1 pint or quart-sized glass jar
• A breathable cover: clean cloth, coffee filter, or paper towel
• A rubber band or jar ring to secure the cover
• A warm, draft-free spot (70–80°F is ideal) but I’ve had success with temperatures in the lower 60s (the yogurt just needs more time).
• A tablespoon

Ingredients

• 2–3 cups of whole or 2% dairy milk
• 1 tablespoon of active mesophilic yogurt or starter culture per cup of milk

🌱 Tip: You can use a freeze-dried mesophilic starter or a few spoonfuls of yogurt from a friend’s batch. See sourcing tips below.

Instructions

1. Prepare your jar.
   Pour 2 cups of milk into a pint jar or 3 cups into a quart jar, leaving some headspace.
   
2. Add the culture.
   Stir in 1 tablespoon of mesophilic yogurt per cup of milk. Mix gently until evenly combined.
   
3. Cover.
   Top the jar with a clean cloth, coffee filter, or paper towel, secured with a rubber band or ring.
   
4. Ferment.
   Leave the jar at room temperature (70–80°F) for 12–24 hours. Begin checking at 12 hours. The yogurt is ready when it thickens and pulls away cleanly from the sides of the jar when tilted. For a more tangy flavor, let it ferment longer.
   
5. Refrigerate.
   Once set, cover with a lid and store in the fridge. Chill before eating to thicken further. It will keep for 1-2 weeks, but try to culture a new batch every week to ensure that your starter is strong.

Yogurt-Making Notes & Resources

• For best results, use high-quality whole milk. Raw or pasteurized milk both work but avoid ultra-pasteurized as it doesn’t maintain a healthy culture over time.
• Save a few spoonfuls of your finished yogurt to culture your next batch.
• Freeze enough yogurt to start a new batch in case you lose your culture. The culture will remain robust in the freezer for up to 6 months.
• There are many varieties of mesophilic yogurt, so try a few to find your favorite.
• Culture sources:
  • Cultures for Health – Mesophilic Yogurt Starter
  • Positively Probiotic

To Serve

Spoon yogurt over Irish or rolled oats or muesli, drizzle with honey and fresh berries, blend into smoothies, or top with fruit as part of your daily breakfast ritual..

Final Thoughts
