Buy Sourdough Starter — Live UK Cultures, Ready to Bake

If you want to buy sourdough starter and actually bake this week, the thing that matters most is whether the culture arrives alive. A live starter wakes up in about two hours. A dried one can take a week of feeding before it lifts a loaf. This page explains the difference, what a fair price looks like in the UK, and how to pick the right one.

Live vs dried: which sourdough starter should you buy?

This is the only decision that really changes your experience, so it is worth two minutes.

Most people who buy a dried starter expecting to bake at the weekend end up disappointed, because it simply is not ready yet. If that is your plan, buy live.

What should you pay for a sourdough starter in the UK?

UK prices sit between roughly £8 and £15. Below that you are usually buying a dried packet with very little culture in it. Above it you are typically paying for a jar and a gift box rather than a better culture.

Watch for three things that quietly change the real price:

• Delivery. A £8.99 starter with £3.50 postage costs more than a £11.99 one shipped free.
• Quantity. Some sellers post 10–15g, which is a thin start. Ask what weight you actually receive.
• The jar in the photo. Several listings picture a glass jar and then ship a plastic pouch. Read the description before you buy.

You only need to buy a starter once. Fed properly, the same culture lasts indefinitely, so a pound or two either way matters far less than whether it arrives alive.

Buy sourdough starter for spelt, rye or wholemeal

You do not need a different culture for every flour. An active starter adapts. Feed it spelt for two or three cycles and it becomes a spelt starter; do the same with rye or wholemeal and it converts just as readily.

Rye tends to ferment fastest and smells sharper. Wholemeal is a good middle ground. Spelt is gentler and a little slower. Buying one culture and converting it is both cheaper and easier than maintaining several jars.

Why buy from Dough Dough at Home

• Lab-verified culture. Our starter is tested for Lactobacillus sanfranciscensis, the bacterium associated with true San Francisco sourdough.
• Ready in about two hours. One feed and you can build a levain the same day.
• 46-year heritage. A mature culture with a properly developed sour note, not a young starter bulked up for sale.
• Free UK delivery. No postage surprise at checkout.
• Printed instructions included. Clear, readable, in the box — plus full guides online.
• Real support. If it misbehaves, message us and we will work it out with you.

What to do the day it arrives

1. Open and transfer. Snip the pouch and scrape the culture into a clean jar of at least 500ml, so it has room to rise.
2. First feed. Add 50g flour and 50ml lukewarm water. Stir until no dry flour remains.
3. Somewhere warm. Leave it loosely covered at 21–26°C. Expect bubbles and roughly double the volume within two to twelve hours.
4. Bake, then keep. Use what you need, leave a little behind, feed it again and store it in the fridge until next time.

Step-by-step detail lives on our instructions page, and if anything looks odd there is a troubleshooting guide too.

Frequently asked questions

Where can I buy sourdough starter in the UK?

You can buy sourdough starter directly from us at Dough Dough at Home. We are a British small-batch producer and ship free across the UK. Every order is a live culture posted in a heat-sealed pouch with printed instructions, so it arrives ready to feed rather than needing days of reviving.

How much does a sourdough starter cost?

Expect to pay between £8 and £15 for a starter in the UK. Ours is £11.99 with free delivery and no jar or subscription required. A single purchase is enough to keep baking indefinitely, because you feed and reuse the same culture rather than buying again.

Should I buy a live or a dried sourdough starter?

Live starter is ready far sooner. A live culture wakes up in roughly two hours after its first feed, while a dried or dehydrated starter typically needs three to seven days of repeated feeding before it can raise a loaf. If you want to bake this week, buy live. Dried is mainly useful as a long-term backup you keep in a drawer.

Is it better to buy a sourdough starter or make one from scratch?

Making your own from flour and water takes roughly 7 to 14 days and often fails on the first attempt, particularly in a cold kitchen. Buying an established culture skips that period entirely and gives you a mature starter with a developed flavour that a two-week-old homemade one cannot match.

What flour do I need after I buy a sourdough starter?

Any decent wheat or rye flour will do. We recommend a strong white bread flour or a stoneground rye for feeding. Plain supermarket flour works perfectly well. Avoid self-raising flour, and use filtered or bottled water if your tap water is heavily chlorinated.

How quickly will my sourdough starter arrive?

UK orders ship free and typically arrive within two to three working days. The culture is shelf-stable in transit and does not need refrigeration on the way to you. Once it arrives, give it one feed and it is ready to bake with.

Can I buy a spelt, rye or wholemeal sourdough starter?

Our culture is fed on wheat flour but converts happily to spelt, rye or wholemeal. Simply feed it with your chosen flour for two or three cycles and it will adapt. Buying one starter and converting it is cheaper than buying a separate culture for every flour.

What happens if my starter does not work?

Get in touch and we will help you troubleshoot, or send a replacement. Most problems come down to kitchen temperature or chlorinated water rather than the culture itself, and both are easy to fix once you know what to look for.
