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.
