Starting a sourdough starter from scratch is one of the most rewarding steps in your baking journey. By using fresh milled flour, you’ll not only enhance the flavor and nutrition of your bread but also create a robust and lively sourdough starter that will serve as the foundation for many delicious loaves. In this guide, I’ll walk you through the simple process of how to start a sourdough starter with fresh milled flour, and share essential tips for keeping it healthy and strong.
Why use fresh milled flour?
Fresh milled flour is packed with nutrients and natural yeast, making it the perfect foundation for your sourdough starter. Unlike commercial flours, fresh milled flour contains all parts of the grain, including the bran and germ, which contribute to a deeper, more complex flavor in your bread. The wild yeast and beneficial bacteria present in fresh flour also help your starter become active and robust more quickly. Additionally, because fresh milled flour hasn’t been sitting on a shelf, it retains more of its natural oils and nutrients, which can lead to better fermentation and a stronger rise in your bread.

Step-by-Step Guide to Starting Your Sourdough Starter
Day 1: Create the Foundation
To begin, combine 10g of fresh milled flour with 10g of filtered water in your glass jar. Stir the mixture until it forms a thick, paste-like consistency. Cover the jar lightly, allowing air to circulate while keeping out dust and other particles. Place the jar in a warm spot in your kitchen, ideally around 72-85°F (22-29°C.). Starting with a small amount of flour minimizes waste, especially since the process involves daily discarding of a portion of the starter.
Day 2: Feed the Starter
On the second day, you may begin to see some bubbles or notice a slight rise in your starter. These are signs that the natural yeast and bacteria are beginning to activate. Discard half of the starter (about 10g) and add 10g of fresh milled flour and 10g of filtered water. Stir until smooth, cover lightly, and return the jar to its warm spot. This daily feeding routine is essential to developing the strength and vigor of your starter.
Days 3-7: Continue Feeding and Observe the Changes
Each day, discard all but 10g of the starter and feed it with 10g of fresh milled flour and 10g of filtered water. As the days progress, you’ll notice the starter becoming more active, with increased bubbling and a tangy aroma developing. The smell of the starter will change over time, often starting mildly sweet and evolving into a more sour and complex scent as the wild yeast and bacteria establish themselves. Continue this process daily to build up the strength of your starter.
Day 8: Your Starter is Ready to Use
By around day 8, your starter should be bubbly, active, and ready to use in baking. A well-developed starter will double in size within 4-6 hours of feeding for at least 3 days in a row, indicating it’s strong enough to leaven your dough. If you’re not planning to bake immediately, you can store your starter in the refrigerator and feed it once a week to keep it alive. At this stage, your starter has become a reliable leavening agent that can be used to create delicious sourdough bread with a unique flavor profile.
How to Care for and Store Your Fresh Milled flour Sourdough Starter
Now that your sourdough starter is established, it’s important to care for it properly to ensure it remains healthy and active. A well-maintained starter can last indefinitely and can be used to bake countless loaves of bread, pancakes, waffles, and more.
Feeding Your Starter
Once your sourdough starter is established, feeding it in larger ratios can help make it stronger and less acidic. This approach is particularly useful if you want to maintain a mild flavor in your bread and ensure that your starter remains robust and active.
How to Feed Your Established Starter:
When your starter is well-established, you can begin to feed it using larger ratios of flour and water. To do this, first, use your starter in baking until all that remains in the container are the scrapings. These scrapings contain enough yeast and bacteria to revive the starter. To feed the starter, add equal parts fresh milled flour and filtered water to the scrapings in the container. You can adjust the amount of flour and water based on your needs. For example, if you plan to bake multiple loaves in the upcoming week, you might feed the starter with a larger amount of flour and water. This method allows you to maintain a strong and active starter while keeping the acidity in check.
Feeding your starter in this way ensures that it remains active and ready for use, whether you’re planning to bake immediately or store it for future use. By adjusting the feeding ratio based on your anticipated baking schedule, you can keep your starter in peak condition, producing consistently great results in your sourdough bread.
Understanding Sourdough Feeding Ratios
Feeding ratios are a key concept in maintaining a healthy and active sourdough starter. Understanding how these ratios work can help you customize the feeding process to fit your baking needs and keep your starter in top condition.
What Are Sourdough Feeding Ratios?
A sourdough feeding ratio refers to the proportion of starter, flour, and water used when feeding your starter. The most common ratio used by bakers is 1:1:1, which means equal parts starter, flour, and water by weight. For example, if you have 50g of starter, you would feed it with 50g of flour and 50g of water.
The ratio you choose to use can influence the activity level, flavor, and consistency of your starter. A higher ratio of flour and water (e.g., 1:2:2) provides more food for the yeast and bacteria, which can lead to a more vigorous rise and a milder flavor, as the starter has more fresh flour to consume. Conversely, a lower ratio (e.g., 1:1:1) results in a faster fermentation process, often producing a more tangy and acidic starter.
How to Apply Feeding Ratios to Your Sourdough Starter
Applying feeding ratios is simple once you understand the concept:
- Determine the Amount of Starter: Decide how much starter you want to feed. For instance, if you have 10g of starter, you’ll base your flour and water amounts on this weight.
- Choose Your Feeding Ratio: Select a feeding ratio based on your needs. For a mild, less acidic starter, you might choose a 1:2:2 ratio, meaning you’ll add 20g of flour and 20g of water to your 10g of starter. If you’re looking for a quicker fermentation or a tangier flavor, you could use a 1:1:1 ratio, adding 10g of flour and 10g of water to your 10g of starter.
- Feed the Starter: Mix the flour and water with the starter until fully incorporated. If you’re feeding with a higher ratio, the starter may take longer to become active, but it will typically have a milder flavor. A lower ratio will ferment more quickly, leading to a stronger, more acidic flavor.
- Adjust Based on Your Baking Plans: If you plan to bake frequently, you can feed your starter with a lower ratio to keep it more active. For less frequent baking, use a higher ratio, which can sustain the starter for a longer period without feeding.
Example Feeding Scenario
Let’s say you’re planning to bake once a week and want a strong but mild starter. You could use a 1:3:3 feeding ratio. If you have 10g of starter, you would add 30g of flour and 30g of water. This larger feeding will result in a less acidic starter that stays active over several days.
On the other hand, if you plan to bake multiple times during the week and prefer a tangier flavor, you might opt for a 1:1:1 ratio. With 10g of starter, you’d add 10g of flour and 10g of water, which will ferment more quickly and be ready to use in a shorter time frame.
By understanding and applying these feeding ratios, you can tailor your sourdough starter’s feeding schedule to match your baking routine and flavor preferences. Whether you want a mild starter that can go a few days between feedings or a tangy starter that’s ready to bake within hours, feeding ratios give you the flexibility to maintain your starter just the way you like it.
Storing Your Fresh Milled Flour Starter
Refrigeration is the best way to store your sourdough starter when not in regular use. To store your starter, simply place it in a clean jar with a lid and keep it in the refrigerator. The cold temperature will slow down the fermentation process, allowing the starter to go longer between feedings. If you’re planning to take a break from baking, you can also dry some of your starter and store it in an airtight container. To dry the starter, spread a thin layer on parchment paper and let it air dry completely. Once dry, break it into pieces and store it in a jar. To reactivate a dried starter, simply rehydrate it with water and feed it over several days until it becomes bubbly and active again. It’s great to keep a backup in case your starter is ever accidentally thrown out or ruined in any way.
Signs of a Healthy Whole Grain Starter
A healthy sourdough starter should have a pleasant, tangy smell and be full of bubbles. It should double in size within a few hours of feeding, and the texture should be thick and stretchy. If your starter develops a layer of liquid on top (called “hooch”), it’s a sign that it needs to be fed more frequently. Simply pour off the liquid and feed your starter as usual. Be cautious of any unusual odors, mold, or drastic changes in texture, which can indicate that the starter has become unhealthy. In such cases, it’s best to discard the starter and begin again.
Troubleshooting Common Issues
Starter Not Rising: If your starter isn’t rising as expected, it may need more frequent feedings or a warmer environment. Make sure your kitchen is warm enough, and consider increasing the frequency of feedings to boost activity.
Sour Smell Too Strong: A very strong sour smell can be a sign of over-fermentation. This can happen if the starter is left too long between feedings or if it’s kept too warm. Adjust the feeding schedule and storage temperature accordingly.
Mold or Unusual Odors: If you notice mold or any unusual odors that are not typical of a sourdough starter, it’s safest to discard the starter and start fresh. Mold can be harmful, and it’s better not to take any risks with your health.
Starting and maintaining a sourdough starter with fresh milled flour may seem like a daunting task at first, but with patience and care, you’ll soon have a thriving culture that can be used to create delicious, nutritious bread. The process not only enhances the flavor and texture of your bread but also connects you to a long tradition of artisanal baking. Whether you’re a seasoned baker or new to the world of sourdough, starting your own starter is a rewarding experience that will bring you closer to the bread you love.
