About this item

Enhance your sourdough game with our optional borosilicate glass dome (sold separately)! It allows for precise temperature control, keeping your starter in the perfect “Goldilocks Zone” of 75-82°F (24-28°C) — where it’s most active and healthy. No more heating up your whole house; just bake perfect bread all year round!
Precision is key! Our device offers degree-by-degree temperature settings from 70-100°F, with a built-in sensor for real-time monitoring. The auto-warming on/off switch and 12-hour timer function allow you to easily adapt to changes in ambient temperature and jar thickness, ensuring optimal results every time.
Pre-calibrated for accuracy, our heater ensures your sourdough starter stays close to the desired temperature. While there may be a slight 3-5 degree variance due to ambient conditions, you can easily adjust the settings to compensate. The intuitive two-zone thermometer (with green and red lights) keeps you informed about the warmer’s status at a glance.
Convenient and energy-efficient, our heater uses a USB plug compatible with any standard USB-to-wall adapter (US or EU, adapter not included). With just 10W of power, it’s a safe, low-energy solution that doesn’t compromise on performance.
A true game changer for home bakers! Quickly heat and activate your sourdough starter, or use the glass dome to transform it into a cozy mini “Warm House” — perfect for keeping your yeast active and thriving all winter long!

    5.0 out of 5 stars Winter must have
    Reviewed in the United States on January 11, 2025
    As soon as winter hit, we’ve been struggling to keep our apartment at a decent temperature. It’s either too cold or too hot, so we air on the side of too cold, but I realized quickly that decision was impacting my starter. This thing has been a life saver. The temperature is consistant and my starter is thriving! Totally worth it!

    If I could give it zero stars I would! This worked fine for a while, and then as I was setting up to bake bread… And for any of you who do bake bread, you know it’s a process of timing… I discovered that hidden shut itself off in the middle of growing my starter… Ruining my baking day!

    We bought a warmer that looks like a fridge but it killed the starter. This one keeps it warm and allows it to thrive.

    2.0 out of 5 stars It was great while it worked!
    Reviewed in the United States on December 28, 2024
    This was a game changer for my sour dough starter. We keep the house fairly cool during the winter, and my starter didn’t like it. The day after I received this, a miracle occurred! My starter went from just being a little bubbly to doubling overnight! Adding the glass dome is definitely recommended.

    The problem is that after about 3 weeks, it kept turning itself off. I tried unplugging it and letting it reset. I changed outlets. Nothing worked. I’m returning it for a replacement. If the replacement lasts, I’ll come back and up my rating. As it is, I can’t recommend it.

    5.0 out of 5 stars Good constant heat
    Reviewed in the United States on January 25, 2025
    My house is always cold so when I want to feed my starter or make sourdough it takes forever to rise. This helps a great deal in allowing for constant heat that can be adjusted to the temp you want. Did get the glass dome to go with it. Only drawback is the height with the glass on it. Do check to make sure your starter jar fits.

    4.0 out of 5 stars makes a big difference, to me there is a workaround for the separate 'dome'
    Reviewed in the United States on December 24, 2024
    This device makes a huge difference to get my starter ramped up for use.
    We keep our house at 55F nighttime which slows the starter down a lot. I had tried seed starting heat mats both under and wrapped around the starter jar and those worked, and one of those I have is temp controlled as well, but this solution is much more compact and manageable on the countertop.

    Folks in comments are talking about the glass dome; I just drape a dishtowel over the jar and this base and the heat gets trapped just fine and the base runs less (has green light when up to temp, so you can tell).

    Taking off 1 star as the unit seems to have some incomplete temp control management. The manual states if you leave it set at >80F for 12 hrs it can/will heat to 100F and burn the starter. leaving at temps under 80F for 12 hrs would be fine. I don't understand why this would be. That said, I know some of the logic here can be hard (remember when rice cookers got "fuzzy logic" and that was a big deal?) Still, read the manual, avoid the situation, but it would be better if the situation didn't occur. My starter can markedly outgrow the jar when I have it set to just 73F, with my house at 55 to 60F. No reason to set it to 80...

    Came with everything included and super simple to use. Simplistic slim design saves counter space. Looking forward to seeing if this helps my starter. If all goes well, I’ll invest in the glass dome as well.

    1.0 out of 5 stars Stoppe working. Not endurable as a warmer.
    Reviewed in the United States on February 8, 2025
    This is a very inconsistent product. The vendor send me a replacement unit which worked for a while but not doesn't work agian. Not sure if the problem is with the power cable, connector or the unit itself. Now it does not remain on.
