About Us

Pakusane began in a winter kitchen during the pandemic, when our founder struggled to keep her sourdough starter alive. Finding no proper warming tool, she created one. In 2022, we launched the world’s first dedicated sourdough starter warmer. Today, Pakusane offers a full range of thoughtfully designed sourdough tools—helping bakers everywhere ferment with ease and joy.

Say Goodbye to Guesswork – Proof Like a Pro. Tired of wondering if your dough is warm enough to rise? Our proofing base integrates a stainless-steel dough probe that measures the core temperature inside the dough itself — not just the air around it. No more guesswork, just consistent fermentation results.
Precision is key! Our device offers degree-by-degree temperature settings from 70-110°F, with a built-in sensor for temperature display. The auto-warming on/off switch and 24-hour timer function allow you to easily adapt to changes in ambient temperature and jar thickness, ensuring consistent results.
Fits Most Jars & Containers – Compatible with mason jars, glass containers, and various fermentation vessels. The adjustable probe works with different jar sizes and shapes, making it versatile for all your sourdough starter needs.
Easy Setup & Use – Simply place your jar on the warming base, insert the probe into your starter, set your desired temperature, and let the device do the work. Perfect for beginners and experienced bakers alike.
Premium Quality & Safety – Made with food-grade materials and featuring automatic shut-off for peace of mind. The sleek walnut finish adds elegance to any kitchen counter while maintaining your starter at the ideal temperature.
Customers find the sourdough warmer works well during bulk fermentation and is essential for serious bakers, significantly speeding up starter rising and proofing times. The temperature control receives mixed feedback – while it keeps starters at the perfect temperature, the surface runs 10-12 degrees F warmer than the thermostat setting, and some units randomly shut off after about a month of use. The product is considered a great addition to sourdough tools and offers good value for money.
