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

Just a really well made, well thought out product. Im super glad I got this for my one gallon jar. The maker includes directions on the side of the box (dont throw it out on accident) that suggets a heat setting based on the season, and your flavor preferences. Our room temp varies between 60-80°F on any given day, and this belt (on the high setting) fermented my kombucha to the perfect F1 flavor in 7 days. Its a really nice accessory to kombucha making that keeps my F1 consistent and tasty! FYI- the cord is not super long. Its not short, just not super long. Just something to consider if the closeness of your outlet to your jars is a factor for you. Check the product description if needed.

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!

I live in the snowy mountains and keep the temperature in my house around 68 degrees in the winter. This mat has worked well to keep a one-gallon jar of kombucha consistently between 75 and 79 degrees. I bought another one for my daughter.

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 quickly One 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

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.

It is cold in Bend OR in winter. Heater helps to keep temperatures appropriate for kombucha making.

This is being sold on Amazon UK however not only does it arrive with a US plug but the required voltage is 120V making it completely unuseable for connecting to mains power here in the UK. I understand that products are not always suitable for all markets and in this case either the product should not appear on Amazon in countries where it is incompatible, or there should be clear and prominent labelling within the description advising prospective customers of this fact. So having wasted a lot of time waiting for this to arrive, I now have to order (and wait for an alternative product) and arrange to drop this item off for return.

Works well, recommended

I have had the heater for just six months and it no longer heats. On their packaging they say just reach out to us on Amazon and we’ll make it right. But apparently if you’re not living in the US, and I’m in Canada, there’s no way to contact them through Amazon. Not only that, but they don’t appear to have any public contact information. I’ve looked all over the place, and there doesn’t appear to be any way to get in touch with them directly. So if they’re going to be selling this unit outside the US, they better find a way to support their customers. I bought this because it has very high ratings, but both the product and the service in my case are a huge disappointment.

Like the product, it arrived incredibly quickly. A week earlier than expected, which was great. HOWEVER it is designed for use with US 120VAC 60Hz mains in mind which means it is a potential fire hazard for a UK customer. You should add words to that effect to the advert.

Le tapis fonctionnait bien mais il est déjà brisé donc aucune chaleur après 6 mois.
