Swiss Mistress™ began with a simple obsession: beautiful bread made with real, wild culture and a touch of attitude.
Born from heritage Swiss grains and a living lineage of natural yeast, our starter was nurtured to be strong, voluptuous, and unapologetically wild — the kind of culture that refuses to be rushed and always rises to the occasion.
From its Alpine origins to its American evolution, Swiss Mistress™ has been passed from baker to baker, hand-fed, tended with devotion, and treated like the living being she is. The result is a sourdough culture with remarkable strength, rich flavor, and personality to spare.
Somewhere along the way, she stopped being “just a starter” and became someone to me.
So, I gave her a name: Marissa.
Marissa is the original Swiss Mistress™ — moody, dramatic, resilient, and endlessly generous.
She’s the mother culture behind every jar we ship, the wild heart of this brand. Naming her wasn’t just cute; it was a reminder that this is a relationship, not a product.
And here’s the fun part:
You get to name yours, too.
When your starter arrives in your kitchen, she’s still Marissa’s lineage — but she’s also fully yours.
Name her, feed her, talk to her, complain about her, brag about her.
Make her part of your rituals and your story.
Because this isn’t just about flour and water.
It’s about connection, ritual, and the feminine energy of creation.
Sourdough is deeply physical — it requires patience, intuition, and willingness to get your hands messy. It rewards slowness, attentiveness, and consistency.
It invites you to surrender control and enjoy the process, not just the outcome.
Swiss Mistress™ exists to honor that sensual, embodied craftsmanship.
We believe that:
Every jar of Swiss Mistress™ starter is hand-fed, carefully maintained, and shipped to you alive, hungry, and ready to thrive.
No shortcuts, no additives, no factory sterilization — just nature, nurture, and a healthy dose of attitude.
When you invite her into your kitchen, you’re not just buying a starter —
You’re beginning an affair with a living culture.
She’ll rise for you, fall for you, surprise you, and occasionally misbehave.
Treat her with care, and she’ll reward you with bread that stops conversations and melts butter at first touch.
Swiss Mistress™ was created for:
So welcome to the family —
or rather, welcome to the affair.
Feed her well
Name her
Watch her rise
Enjoy every bite
Swiss Mistress™
