About Swiss Mistress Sourdough

Our Story

 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:

  • Fermentation is art 
  • Bread is ritual 
  • Food should be beautiful 
  • And nothing good is ever rushed
     

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:

  • Bakers who believe in ritual
  • Food lovers who crave depth
  • Creators who appreciate slow craftsmanship
  • And anyone who wants a little seduction in their sourdough
     

So welcome to the family —
or rather, welcome to the affair.


Feed her well
Name her
Watch her rise
Enjoy every bite

INSTRUCTIONS

Swiss Mistress Liquid Starter

Congratulations on beginning your journey with Swiss Mistress™ — an authentic, mountain-bred sourdough culture nurtured with patience, purity, and a little alpine attitude.

Your starter has traveled far, and she will be hungry.
Feed her as soon as she arrives to help her wake, stretch, and reclaim her strength.


💧 Water Matters

Avoid:

  • Distilled
  • Reverse osmosis
  • Ozonated
  • Alkaline water 

These types can starve or kill yeast. Use natural spring water whenever possible.
It’s cheap, reliable, and yeast-friendly.


🌾 Flour Matters Too


Avoid:

  • Bleached flour
  • Enriched flour
     

They contain additives that weaken or kill wild yeast.


Best options:

  • King Arthur Unbleached All-Purpose Flour OR
  • King Arthur Bread Flour
     

🥣 Texture & Measuring


If using cups/tablespoons, you may need to adjust a little.

You are aiming for:

  • Thick, smooth, and spreadable 
  • Like smooth peanut butter 
  • No dry spots
     

🧰 What You’ll Need


  • 1 quart (32 oz) glass jar with lid
  • Unbleached flour
  • Natural spring water
  • Spoon, patience, maybe wine
     

🥖 First Feeding — “Wake Up Call”


  1. Place starter into a 32 oz jar.
  2. Add 3 tablespoons lukewarm spring water and stir
  3. Add ½ cup unbleached flour (AP is fine).
    • Optional: ¼ cup AP + 2 tablespoons whole wheat

  1. Mix until thick and smooth.
  2. Add a little extra flour or water if needed to get peanut-butter texture.
  3. Cover loosely (not airtight).
  4. Let sit at room temperature.

 

She should double or triple in 1–3 days.
Travel makes her sluggish — don’t panic.

Visual signs of life:

  • Bubbles
  • Risen & fallen streaks
  • Clear liquid on top (hunger, not failure)
     

If she gets hungry before doubling, move to the second feeding early.


🥖 Second Feeding — “Establishing Rhythm”


When she’s doubled OR liquid appears:

  1. Keep 2 tablespoons starter, discard the rest.
  2. Add ¼ cup lukewarm water and stir.
  3. Add ½ cup unbleached flour
    • Optional: ¼ cup AP + 2 tablespoons whole wheat 
    • Mix until smooth.

  1. Cover loosely and rest.
     

This time, she should double in 6–12 hours depending on temperature.


🥖 Daily Maintenance — “Building Strength”


Once she’s reliably doubling:

Feed daily:

  1. Keep 3 tablespoons starter
  2. Add ¾ cup flour
  3. Add ½ cup water
  4. Mix smooth
  5. Let rise fully before feeding again 


Only feed after she has doubled in size. This builds strength, flavor, and structure.

Do this for about one week before baking.


❄️ Long-Term Storage — “The Alpine Sleep”


After a week of daily feedings:

To store in the fridge:

  1. Feed as normal 
  2. Let her double at room temp 
  3. Place in fridge
     

Once refrigerated, feed once per week:

Always clean the jar to keep her healthy.

Swiss Mistress Dry Starter

 

Congratulations on beginning your journey with Swiss Mistress™ — an authentic, mountain-bred sourdough culture preserved in a dormant state, waiting to be revived with patience, purity, and a little alpine attitude.

Your dried starter is asleep.
 

Rehydration is her wake-up call.


💧 Water Matters


Avoid:

  • Distilled 
  • Reverse osmosis
  • Ozonated

These starve yeast.

Use natural spring water — it keeps the culture happy, stable, and active.


🌾 Flour Matters Too


Avoid:

  • Bleached flour 
  • Enriched flour

Best options:

  • King Arthur Unbleached All-Purpose Flour OR
  • King Arthur Bread Flour

  3. Let rest at room temp.


She may take 24–72 hours to show activity.

She’s been asleep — let her wake up slowly.


Signs of life:

  • Bubbles
  • Expansion
  • Clear liquid on top (hunger, not failure)
  • Stretchy texture
     

If she’s hungry before doubling, feed early.


🥖 Step 2 — First Real Feeding


When the starter is showing activity (rising, bubbling, or hungry):


  1. Keep 2 tablespoons starter, discard the rest.
  2. Add ¼ cup lukewarm water and stir.
  3. Add ½ cup unbleached flour.
  4. Mix until smooth and thick.
  5. Cover loosely and rest.

  2. Add ¾ cup flour
  3. Add ½ cup water
  4. Mix smooth

🥖 Tips for Faster Activation

If she seems slow at first (very normal):

  • Use a little whole wheat flour (1–2 tbsp)
  • Keep her in a warmer spot (75–80°F) 
  • Be patient — dried cultures take time to reawaken
     

❤️ A Note from Swiss Mistress™


Your starter is alive, old-soul, and fiercely independent.

She responds to:

  • Good flour
  • Clean water
  • Consistency
  • And a bit of love
     

In return, she will give you:

  • Strong rise
  • Tangy, complex flavor
  • Open, luxurious crumb
  • And breads worthy of an alpine bakehouse
     

Treat her well — and she’ll make magic.
