Where to Buy Sourdough Starter in the UK?

Sourdough bread is rapidly growing in popularity, increasingly becoming a staple in many households. With its rich, tangy taste and numerous health benefits, it's no surprise that more and more people are discovering this incredible bread. However, making sourdough bread involves a sourdough starter, which is essentially a fermented dough made from flour and water. For some, making a sourdough starter from scratch can seem intimidating, time-consuming, and require a lot of trial and error. Luckily, many options are available to purchase sourdough starters in the UK. In this article, we'll explore some of the best places to buy sourdough starters in the UK.

Understanding Sourdough Starters

Before diving into where to buy sourdough starters, let's take a quick look at what sourdough starters are and why they're necessary for making sourdough bread.

Sourdough bread has become increasingly popular in recent years, with many people opting for this type of bread over commercially produced bread. This is because sourdough bread is not only delicious but also healthier.

What is a Sourdough Starter?

In simple terms, a sourdough starter is a fermented mixture of flour and water that contains wild yeast and beneficial bacteria. Once mixed and left at room temperature, these microorganisms ferment the mixture, producing carbon dioxide gas that gives the bread its characteristic rise. More importantly, the lactic acid bacteria and acetic acid bacteria present in sourdough starter improve the bread's taste, texture, and nutritional value, and it can also improve the bread's keeping quality. Once established, a sourdough starter needs to be maintained regularly.

The process of creating a sourdough starter can take several days, but the results are worth it. The starter can be used to make a variety of bread, including sourdough loaves, baguettes, and even pizza dough.

The Benefits of Sourdough Bread

Sourdough bread is a healthier option than commercially produced bread. It's easier to digest and has a lower glycemic index. It also contains higher amounts of antioxidants, vitamins B and E, iron, magnesium, and other essential nutrients that are vital for good health.

In addition to its nutritional benefits, sourdough bread has a unique flavour that is hard to replicate with commercially produced bread. This is because the fermentation process in sourdough bread is longer, allowing the flavours to develop more fully.

How to Maintain a Sourdough Starter

To keep a sourdough starter active, it needs to be fed with fresh flour and water regularly. The feeding process involves discarding some of the starter and replacing it with fresh flour and water. For optimal growth, the sourdough starter should be kept at room temperature away from direct sunlight and drafts.

It's important to note that sourdough starters can be sensitive to changes in temperature and humidity. If the starter is not maintained properly, it can become inactive or even die. However, with regular feeding and proper care, a sourdough starter can last for years.

So, if you're looking to make your own sourdough bread, investing in a sourdough starter is a great place to start. Not only will you be able to enjoy delicious and healthy bread, but you'll also have the satisfaction of knowing that you made it yourself.

Local Bakeries and Sourdough Suppliers

If you prefer to buy locally, you can purchase sourdough starters from local bakeries and sourdough suppliers. Here's how:

Finding a Local Bakery

When looking for a local bakery to purchase sourdough starters, consider checking out reviews online or asking friends for recommendations. You may also want to look for bakeries that specialise in sourdough bread, as they are more likely to sell starters. Once you find a bakery, try to visit during their busiest times, as this is when they are most likely to have fresh starters available.

When you visit the bakery, be sure to ask the baker about their sourdough starter. They may be able to tell you about the history of the starter, how long they've been using it, and any tips or tricks for using it.

Sourdough Starter Exchanges

Joining a sourdough starter exchange can be a fun way to obtain a starter for free and connect with other bakers. These exchanges operate online and allow bakers to swap starters with each other. Not only does this allow you to try out a unique strain of sourdough starter, but it also helps to keep the tradition of sourdough baking alive.

When participating in a sourdough starter exchange, it's important to follow the guidelines set by the group. These guidelines may include rules about how to package and ship the starter, as well as how often to participate in the exchange.

Farmers' Markets and Food Festivals

Visiting farmers' markets and food festivals can be a great way to buy sourdough starters directly from artisan bakers and suppliers. These events often feature local vendors who are passionate about their products and are happy to share their knowledge with customers.

When purchasing a sourdough starter at a farmers' market or food festival, take the time to talk to the vendor about their product. They may be able to tell you about the specific strain of starter they use, how to care for it, and any unique characteristics it may have.

Overall, buying a sourdough starter from a local bakery or supplier is a great way to support small businesses and connect with other bakers in your community. Whether you choose to participate in a sourdough starter exchange or visit a farmers' market, there are many options available to help you find the perfect starter for your baking needs.

Supermarkets and Health Food Stores

If you're in a rush, several supermarkets and health food stores also sell sourdough starters, although your options may be limited. However, it's important to note that making your own sourdough starter can be a fun and rewarding experience. Not only will you have control over the ingredients, but you'll also have the satisfaction of creating your own unique bread.

If you decide to make your own starter, all you need is flour, water, and time. The process can take anywhere from 5 to 10 days, depending on the temperature and humidity of your environment. There are many resources available online to guide you through the process, including step-by-step instructions and troubleshooting tips.

Major Supermarket Chains

Major supermarket chains, such as Tesco and Sainsbury's, sell a variety of sourdough starters, mostly in powder form or with a short shelf life. While these options may be convenient, they may not offer the same quality as a fresh, homemade starter. If you're looking for a more authentic sourdough experience, consider making your own starter or seeking out a local bakery that sells their own.

It's also important to consider the environmental impact of purchasing pre-made starters. By making your own, you can reduce packaging waste and potentially save money in the long run.

Independent Health Food Stores

Local independent health food stores may also sell a variety of sourdough starters. These stores often prioritise organic and locally-sourced products, which can be a great option for those who value sustainability and supporting small businesses.

When shopping at independent health food stores, be sure to ask the staff for recommendations and advice. They may be able to provide valuable insight into the different types of starters available and which would be best suited for your needs.

Organic and Specialty Food Shops

Organic and specialty food shops also sell a great selection of sourdough starters. These are often sold as fresh or dried cultures, which you can easily activate at home. Some shops may even offer classes or workshops on sourdough baking, which can be a fun way to learn more about the process and connect with other bread enthusiasts.

When purchasing a starter from an organic or specialty food shop, be sure to read the ingredient list carefully if you have any dietary restrictions. Some starters may contain ingredients like dairy or honey, which may not be suitable for everyone.

Overall, there are many options available for purchasing sourdough starters. Whether you choose to make your own or purchase from a store, the most important thing is to have fun and enjoy the process of creating delicious, homemade bread.


There are ample opportunities to buy sourdough starters in the UK, whether online, in a local bakery, or even from a supermarket or health food store. By following the recommended maintenance and care instructions, you can make fresh sourdough bread daily that is both delicious and healthy. Happy sourdough-making!
