Who we are

Welcome to Sustainable Sourdough—a certified residential bakery rooted in passion, purpose, and the joy of truly good bread. I'm Jen, a lifelong baking enthusiast who turned a love for sourdough into a mission-driven microbakery.

At Sustainable Sourdough, we focus on thoughtful, small-batch baking using locally sourced ingredients and grains and eco-friendly practices—including biodegradable packaging, local banking and conscious consumerism. Based in Boston, MA, we offer “Bread Drops” of freshly baked breads, jams, and more. Additionally, you can look forward to seeing us at markets and pop-up events across the area.

This isn’t just about bread—it’s about building community, celebrating local ingredients, and making choices that support our planet. Follow along on Instagram for market updates, behind-the-scenes peeks, and the evolving journey of this little bakery with a big heart.
