How to Create Your Own Sourdough Starter
Creating a sourdough starter is like starting a relationship with your very own wild yeast colony—one that will reward you with delicious, crusty loaves for years to come! Here's how we like to get things bubbling at The Sourdough Kitchen, with a few personal tips that make all the difference.

What You'll Need:
● High-grade flour: This will give you the best results, trust us! It’s strong, full of good nutrients, and gives your yeast the energy it needs to thrive.
● Water: Clean, filtered water if possible. Yeast and bacteria are sensitive little creatures and they don’t appreciate chlorine or impurities.
● A clean glass jar: Clear so you can admire your starter’s progress.
Step-by-Step Guide:
Day 1:
Mixing the Base:
Combine 50g of high-grade flour with 50g of water in your jar. Stir until smooth, ensuring there are no lumps of flour. Cover loosely with a lid or cloth to allow airflow. Yeast and bacteria need to breathe, but we don’t want any unwanted guests. Place it somewhere warm and cozy. In our kitchen, the hot water cupboard works wonders. In cooler months, be patient—growth will naturally be slower.
Day 2:
Feeding it
By now, you might notice some bubbles or even a slightly sour smell. This means things are on track! Discard about half of your starter (don’t worry, this is normal) and add another 50g each of high-grade flour and water. Stir again and return it to its warm spot. If it's winter, you may see slower progress but don't worry, things will still happen! You may need an incubator to keep the temperature high enough.
Days 3-5:
Keep the Feeding Going
For the next few days, you'll repeat the same steps: discard half, feed it 50g flour and 50g water, and stir. Bubbles should appear more frequently, and the smell will become more pronounced.
If it’s still looking sluggish, especially during winter, don’t be discouraged. A cozy spot (back in the hot water cupboard!) can help, but sometimes it just takes a little extra time for the yeast to flourish.



How to Know It’s Ready:
Your starter should be bubbly, active, and have a pleasant sour smell after 5-7 days. It will also have doubled in size between feedings. Once it reaches this point, it's ready to become the star ingredient in your sourdough bread recipes!
Final Tip:
Once your starter is established, keep it happy by continuing regular feedings. You’ll soon have a robust, lively starter that becomes more flavorful with time.


Frequently Asked Questions
How long does it take to make a sourdough starter from scratch?
Patience is essential! Some starters become active in 5–7 days, while others can take 10–14 days or even longer, especially in cooler weather. Don't give up if yours seems slow—it often just needs more time and consistent feeding.
My starter doesn't seem to be doing anything. Should I start again?
Not necessarily. A lack of bubbles in the first few days is completely normal. Keep feeding it as directed and maintain a warm environment. In colder climates or during winter, using a starter incubator or proofing box can make a big difference and help encourage healthy activity.
My starter smells strange. Is that normal?
Yes! As the natural yeasts and bacteria develop, your starter may smell fruity, tangy, cheesy, or even a bit like dirty socks. These changing aromas are usually a sign that fermentation is happening. However, if you see coloured mould or pink or orange streaks, it's best to discard the starter and begin again.
Should I keep using the same flour?
Yes. Sticking with the same type of flour during the early stages gives your starter the best chance to establish a stable microbial community. Once it's active, bubbly, and rising reliably, you can experiment with different flours if you wish.
How important is cleanliness?
Cleanliness is very important when creating a sourdough starter. Always start with a clean jar and clean utensils to reduce the risk of unwanted bacteria or mould. We often sterilise our equipment by pouring boiling water over jars and tools before use, then allowing them to cool completely. This simple step helps give your wild yeast and beneficial bacteria the best chance to thrive.
