Why Is Everyone Suddenly Obsessed With Sourdough?

There was a time when bread was just your average breakfast. A quick rise, a fast bake, sliced, toasted, bagged, done. And then came sourdough. It is slow, slightly temperamental, sour, and common plus-one alongside avocado toast and other wellness-focused sandwiches. From bakery queues to Instagram reels, this ancient method of bread-making has recently become one of the most talked-about foods. But unlike most food trends, sourdough isn’t built on hype but on time.

​As they say, good things come to those who wait, and yes, it’s this concept of patience that transforms something as simple as flour, water, and salt into a loaf that tastes richer, lasts longer, and feels far more considered than your average supermarket bread.

​The initial spark that brought sourdough back to our plates was the pandemic. With far too much time on our hands and not enough things to do, people were looking towards hobbies to find purpose at home. Sourdough, naturally, became one of the right answers.

In an era obsessed with clean eating, mindful consumption, and “back to basics” living, sourdough fits right. It’s prepared with no additives, no shortcuts and yet delivers  better flavour, improved digestibility, and even a gentler impact on blood sugar compared to regular bread. Add to that the cultural shift towards craft. People want to know more about the source of their food and how it’s made. And sour bread is very up with the times.

How Sourdough Is Made

When it comes to sourdough, the main thing to remember is that it isn’t a type of bread as much as it is a process. Instead of using commercial yeast, it relies on natural fermentation by wild yeast and bacteria already present in flour and the environment. The signature tang and complexity come from this slow fermentation, which tends to take anywhere from 12 to 48 hours. During this time, the dough develops lactic and acetic acids—the same compounds responsible for that slightly sour flavour.

​What gets the process going? The starter, often romantically called the mother dough is where the magic lives.

​A sourdough starter, in layman’s terms, is simply flour and water left to ferment. It captures wild yeast and bacteria from its surroundings and turns them into a living culture. Over days (sometimes weeks, months, and years), it’s fed, nurtured, and kept alive, essentially functioning as a natural leavening agent that replaces commercial yeast. When added to fresh dough, it produces gas that helps the bread rise, while it develops a flavour that instant yeast could never yield. 

​For many, this starter is barely an ingredient. And for those dedicated to sourdough-baking for generations, it’s as important as the final product. Each starter is slightly different— shaped by the flour you use, the air in your kitchen, and even the bacteria on your hands. It evolves, adapts, and, if you take care of it, can live on indefinitely!

The oldest mother doughs have been passed down by ancestors as parts of wills, shared across generations as heirlooms, and even named (yes, really). And perhaps that’s why sourdough has endured centuries. In a world that moves fast, it insists that some things are worth waiting for.

A Brief History Of Sourdough

Long before supermarket loaves and sachets of instant yeast, there was sourdough. According to many historians, this was the original way humans actually learned to make bread rise.

The story goes back thousands of years, around 1500 BC to 3000 BC, to the earliest days of agriculture in regions like the Fertile Crescent and ancient Egypt, where grains were first cultivated and ground into flour. However, somewhere along the way, a mixture of flour and water was left out long enough for the wild yeast in the air to react and ferment. The rest, as they say, is history. The dough bubbled, rose, and baked into something lighter, tangier, and unexpected: the sourdough we know and love.

By around 3700 BCE, we already have archaeological evidence of sourdough bread being made in parts of Europe, and references from ancient writers like Pliny the Elder show how widespread the technique had become. For most of human history, this was the way to make bread. There were no shortcuts. It wasn’t until the Middle Ages that alternatives like barm (a byproduct of beer brewing) began to replace it, and much later, in 1868, commercial yeast entered the market, changing bread-making forever.

As trade routes expanded and cultures intertwined, sourdough travelled with them. Every region adapted it to local grains, climates, and tastes—from the dense, tangy loaves of Northern Europe to the iconic San Francisco sourdough, shaped by the city’s unique microflora. What stayed constant, though, was the idea of the mother dough.

And that brings us to the almost mythical question: how old can a sourdough starter really be? While many bakeries proudly use starters that are decades or even centuries old, tracing a single, continuous lineage is tricky. What we do know is this: scientists have successfully revived yeast from ancient Egyptian vessels over 4,500 years old, using it to bake bread today. It’s not quite the same jar of starter sitting untouched for millennia, but it does connect modern baking directly to one of the earliest known bread-making cultures.

The Best Sourdoughs To Try In India

Weirdough The Artisan Bake, Mumbai

Born as a lockdown micro-bakery, the brand is all about slow fermentation and clean baking, using an in-house starter and keeping ingredients minimal and additive-free.

The offerings are also tightly curated around this philosophy. Their core lies in artisanal sourdough loaves—from classic country bread and whole wheat to more indulgent variations like jalapeño cheddar, olive-roasted garlic, sundried tomato chilli, and even dark chocolate sourdough. For those who love sourdough in almost everything, there’s also sourdough pizzas, flatbreads, focaccia, and pull-apart breads.

La Folie, Mumbai

Known primarily for its desserts and chocolate, the brand’s approach to bread follows the same philosophy—detail-oriented, ingredient-led, and meticulous. Their loaves are built on natural fermentation, using a house starter and long proofing to develop flavour and structure. The result is a tight, even crumb loaf with a very balanced, subtle flavour.

You’ll find classic sourdough loaves alongside softer formats like brioche and milk breads, often used across their café menu for sandwiches and toast-based dishes.

Suchali’s Artisan Bakehouse, Delhi

Suchali’s Artisan Bakehouse has perfected most baked goods for the capital, and sourdough is no different.

Built around naturally leavened baking, you’ll find everything from classic country loaves and 100% whole wheat to more flavoured options like olive & rosemary, multigrain, seed feast, and jalapeño cheddar. Beyond loaves, sourdough shows up across the menu in softer sandwich breads and café-style plates like avocado or guacamole on toast, scrambled eggs on sourdough, and other brunch staples.

Miche Artisan Bakery, Delhi

At Miche Artisan Bakery, the loaves rely on a traditional starter, flour, water, and salt—no commercial yeast, no additives—keeping things as close to “real sourdough bread” as it gets.

The menu reflects that simplicity while offering enough variety to keep things interesting. You’ll find all the classics, country sourdough, whole wheat, and multigrain, alongside more flavour-forward loaves like walnut & cranberry or cheese and jalapeño. Their olive and rosemary sourdough, for instance, leans into a slow-fermented base layered with briny, aromatic notes, while seeded and wholegrain options bring in texture and a more wholesome bite.

Add to that seasonal variations and even subscription-style bread deliveries, and Miche is your one-stop shop for baked goods.

Sour House, Bengaluru

What started as a small, almost obsessive experiment with natural fermentation in Koramangala has become a full-fledged project, built around the idea of bringing slow, traditional food back into everyday eating.

At its core—as the name suggests—are their sourdough breads, all made using long fermentation and minimal ingredients. There’s also flavour-forward options for those who prefer their loaves with a kick of spice (or rosemary or cheese), but it doesn’t stop at loaves. The menu stretches into baguettes, ciabatta, focaccia, crackers, and even pizza bases, all built on the same naturally leavened foundation.

What makes Sour House particularly interesting is how far they take fermentation beyond bread. You’ll find kombucha, kefir, kimchi, and other gut-friendly foods sitting alongside their bakes, turning the space into something closer to a fermentation lab than a standard bakery.
