Confidence first
Clear guidance, dependable products and support when a bake does not go to plan.
Our story
We help home bakers begin with a dependable sourdough starter, clear guidance and tools chosen for real kitchens.


Why we began
Sourdough by the Sea is a small independent baking business, founded in Brighton in 2022 and now based by the sea in Newhaven.
Sourdough is simple at heart, but the first steps can feel uncertain. We began with one aim: to make it easier to start with a dependable culture and know what to do next.
That original starter has grown into a range of practical baking tools and gift sets designed for real home kitchens—not professional bakeries.
Our starter cultures and gift sets are prepared and packed by hand in Sussex. Clear guides, tested recipes and friendly support help our customers keep baking long after the parcel arrives.
What matters to us
Clear guidance, dependable products and support when a bake does not go to plan.
Useful tools, carefully chosen ingredients and recyclable packaging, selected for how people actually bake at home.
Bread brings people together. Our products are designed around that simple pleasure.
A small independent business shaped by the coast, its community and a slower way of living.
Meet the founder
I’m Jim Callender, founder of Sourdough by the Sea. I started the business in Brighton in 2022 after discovering how satisfying—and sometimes confusing—sourdough baking can be.
What began with a dependable starter culture has grown into a range of kits, tools and practical guides designed to help more people bake confidently at home.
Today, our starters and gift sets are prepared and packed at our workshop by the sea in Newhaven. When I’m not working here, you’ll usually find me running or cycling across the South Downs, walking the Sussex coast with my family, or working with wood in my other workshop.
