The Hearth Keeper: A Sourdough Starter Companion

To bake sourdough is to be a custodian of a living thing. The starter—that bubbling, breathing culture of wild yeast and bacteria—is the heart of the loaf. It’s a partner in the baking process, with its own rhythms, needs, and moods. And as any baker knows, its vitality is profoundly tied to temperature.

The Sentient Chamber: A DIY Wireless Fermentation Controller

Fermentation is a dance between control and surrender. We create the conditions, add the culture, and then step back to let an invisible world of microbes work its magic. But any fermenter knows that the environment is everything. The wild sourdough that thrives in a cool, humid kitchen might struggle in a warm, dry one. The perfect kimchi requires a consistent chill. A home-brewed beer like a lager demands a precise, unwavering cold fermentation, while an ale needs a steady warmth. The mash for a future distillation, perhaps using surplus lemons or plums from your own garden, needs to be kept at an optimal temperature to ensure a clean ferment, free of off-flavours. Even a simple Hard Lemon brew can turn if the temperature swings too wildly.

Fermentation as a Revolutionary Act

What if one of the quietest ways to resist our broken food system is simply… to let food sit? To watch it bubble, fizz, and transform — guided not by factories or corporations, but by microbes, time, and our own hands?

Microbial Lessons for a Living Planet

When we begin to see fermentation not as a human trick but as a conversation between species, something shifts. The jar on the counter becomes a small model of the world — alive, adaptive, and full of intelligence that isn’t our own. These microbial communities show us, in miniature, how life sustains itself through cooperation, balance, and exchange.

The Intelligence in the Jar

If you’ve ever stood over a jar of fermenting vegetables — watching bubbles rise, catching that sharp, tangy scent — you’re witnessing something extraordinary: an invisible ecosystem, busy at work.
