Hemlock Home BrewingKombucha Heating Wrap - Fermentation Heater Mat Pad with Temperature Control

I love this so much. Perfectly holding temperature. Set it and forget it. I just ordered #2. I highly recommend it.

I ordered two of these and they arrived yesterday. I'm really impressed with the thickness of the glass! So far, I'm pleased with the quality and look forward to making my first batch of kombucha.

I nearly returned it on the first day, thinking it wasn't working, but it just heats up slowly. The heat is concentrated at both ends of the mat. Once set, it maintains a consistent temperature, and my kombucha turned out great!UPDATE: I'm upgrading my rating to 5/5 stars. I really like how reliable it's been in maintaining the temperature of my Kombucha, I didn't have to worry about it at all. I ended up ordering a second pair for my 2-gallon jar, and it fits well! I also appreciate the temperature sticker included with each order and the spacing it has to view it. Thank you!

I have now purchased 2 of these wraps because they work so well!I brew kombucha and needed a heating wrap since our house gets chilly overnight during the winter months.This is truly a ‘set it and forget it’ solution! To enjoy the success I have with my kombucha simply read the directions that are on box the wrap comes in and you’ll be on your way to easy maintenance and delicious brews.There are 3 settings: High, Medium, Low. The info on the box outlines how to determine which setting to use, and when.When the wrap is used with a 1 gallon round glass jug it leaves a space to view a temperature strip if you use them, which I do. Many products of this type wrap completely around the vessel which makes it more difficult to check the temperature when necessary.The dimensions of it provide even heating for the vessel size I mentioned above. This is a big consideration when fermenting since you don’t want all the heat in one spot.It’s definitely a well thought out design and is a great value for the money since it will help make F1 a success each and every time!

Did exactly what I needed. The low setting was too low, so bumped it up to the medium setting and it tea up to 79 F. Easy to wrap around the one gallon jar.

I have been a home brewer (wine/beer) for over 30 years. I began making Kombucha a few years ago and have been making one gallon batches of it just using room temperature in a warm furnace room as the temperature control. As might be expected the results varied due to having inconsistent temperature control. I recently purchased this heater which is specifically designed for kombucha and am extremely pleased with the results.The design is excellent. It was designed by a home brewer who obviously thought out solutions to the common design problems. It fits a standard one gallon jar and leaves a vertical gap in the wrap around heater to be able to easily read the vertical stick-on temperature strip that comes with the unit. The wrap-around heater element is held with a velcro strap and has three selectable heat levels plus an off level with an easy to read indication of the level. It has two indicator lights. One green to show that you have line power attached and one red to indicate that the heater has been turned on.Using a power meter it drew 12 watts on high, 9 watts on medium and 4 watts on low. At the mid level heat setting this heater kept my one gallon batch at a perfectly constant 82 deg over 7 days even though it was in a room where the air temperature varied from 67 deg to 72 deg over the course of a day. The batch finished to my taste in 7 days compared to the usual 10 to 12 days before the I used the heater.An excellent product. I highly recommend it for anyone interested in making consistent kombucha quicklyOne thing I would suggest to the designer/seller - the very useful suggestions for how to use the three heat settings to achieve specific results are printed on the side of the packaging box. I almost threw the box out without reading it. I would strongly suggest that you print that info on an insert and put it in the box
