The Benefits of Fermenting Your Own Yogurt at Home

Why homemade yogurt has become one of my favourite gut-health rituals

There has been a lot of hype around yogurt lately — and honestly, much of it is justified.

We are learning more every year about the importance of the gut microbiome and how deeply it impacts our overall health. From digestion and immunity to mood and inflammation, the tiny microbes living in our gut play a massive role in how we feel day to day.

One voice that has influenced my curiosity in this area is Dr. William Davis, author of Wheat Belly and Super Gut. While I always encourage people to do their own research and listen to their bodies, his work sparked a new passion for me this past year: making homemade fermented yogurt.

And once I started, I never went back.

Why Make Yogurt at Home?

At first glance, yogurt seems like something easier to buy than make. But once you understand what’s possible with homemade fermentation, it becomes a completely different food.

When you ferment yogurt at home, you gain full control over:

• The probiotic strains you use

• The fermentation time

• The thickness and texture

• The milk base

• Additives (or lack of them)

In other words, it transforms yogurt from a passive grocery item into an intentional, functional food.

For me, this control matters. I am lactose intolerant, so I ferment using lactose-free cream to create a thick, rich yogurt that is gentle on my system. But one of the beauties of fermentation is flexibility — you can use whole milk, A2 milk, goat milk, or higher-protein dairy depending on what works for your body.

Not All Yogurt Is the Same

This is one of the biggest misconceptions I see.

Most commercial yogurts contain relatively low probiotic counts and are fermented for short periods of time. Many are also sweetened, flavoured, or stabilized with additives.

Homemade yogurt — especially long-fermented yogurt — can contain dramatically higher bacterial counts and more targeted strains.

Over time, I’ve experimented with:

• Store-bought yogurt as a starter (with unknown strains)

• Specialty probiotic starters

• Targeted strains recommended by fermentation communities

This experimentation is part of the joy. Fermentation invites curiosity.

The Strains I Love Working With

While there are many beneficial bacteria, a few have become favourites in my kitchen.

L. reuteri (a popular gut-health strain)

This strain has gained attention in fermentation circles for its potential connection to gut balance and overall wellness. Many people explore it because of research suggesting possible links to:

• Microbiome diversity

• Immune resilience

• Skin and metabolic health

• Hormonal signalling (including oxytocin pathways)

While experiences vary from person to person, many home fermenters are drawn to this strain because it behaves beautifully in yogurt and produces a mild, creamy result.

L. rhamnosus + L. gasseri (a powerful pairing)

Another combination I enjoy fermenting includes Lactobacillus rhamnosus and Lactobacillus gasseri. Together, they are often used in functional probiotic fermentation because they may support:

• Gut barrier strength

• Digestive balance

• Reduced inflammation

• Immune support

• Metabolic health

This pairing tends to create a thicker, tangier yogurt with a lovely complexity.

The Joy of Controlling Fermentation Time

One of the most fascinating aspects of making yogurt at home is adjusting fermentation length.

Short fermentation = milder flavour and lower bacterial counts

Long fermentation = tangier yogurt and higher probiotic density

This is where homemade yogurt really shines. You can tailor the process to your goals, whether that’s flavour, digestibility, or probiotic density.

It becomes less about “making yogurt” and more about cultivating living food.

Equipment: What You Actually Need

The good news? You don’t need a lab to do this.

Over time, I’ve experimented with a few different tools.

Instant Pot (My current favourite)

The yogurt setting on an Instant Pot has given me the most consistent results. It maintains stable temperatures and removes much of the guesswork, making it ideal for beginners.

Dedicated Yogurt Makers

I’ve recently added a few yogurt makers to my kitchen and am excited to compare results, including:

• Individual-jar yogurt makers (great for portion control)

• Larger single-vessel fermenters with timers

Each tool offers a slightly different experience, and part of the fun is discovering what works best for your rhythm and lifestyle.

But truly — you can start simple.

At its core, yogurt fermentation only requires:

• A clean vessel

• A starter culture

• Milk (or alternative)

• A warm, stable environment

That’s it.

Why Fermented Yogurt Matters

Beyond flavour and texture, what keeps me coming back to homemade yogurt is how empowering it feels.

Fermentation reconnects us with traditional food wisdom — the idea that food can be both nourishment and transformation.

When you make yogurt at home, you are:

• Cultivating beneficial bacteria

• Reducing reliance on ultra-processed foods

• Lowering packaging waste

• Supporting gut diversity

• Reclaiming a lost kitchen skill

From a sustainability perspective, fermentation is deeply aligned with slow food values. It’s low-energy, low-waste, and rooted in ancestral knowledge.

A Few Real-Life Lessons From My Kitchen

If you’re new to yogurt fermentation, here are a few things I’ve learned along the way:

• Your first batch may not be perfect — and that’s okay

• Texture varies widely depending on milk and strains

• Clean equipment matters more than fancy equipment

• Fermentation teaches patience

• Every batch teaches you something

Like sourdough or gardening, fermentation rewards curiosity.

A Gentle Encouragement

If you’ve been yogurt-curious but hesitant to try, consider this your invitation.

Start simple. Use what you have. Choose a milk that works for your body. Let the process teach you.

You don’t need to chase perfection — just begin.

Homemade yogurt has become one of my favourite food rituals. It sits at the intersection of nourishment, sustainability, and self-reliance — three things that are deeply woven into the philosophy of EcoChef Academy.

And perhaps that’s the real magic of fermentation.

It reminds us that transformation doesn’t always require complexity — sometimes it just needs warmth, time, and a little life.
