It can be a challenge for the first-time home brewer to get the equipment required to brew a full 20 litre (5.5 gallon) batch. Particularly at the beginning, most people want to keep costs low to ensure that they will enjoy the brew making process. So it’s recommended that you start with the tools you have.
It is possible to brew beer right on your electric stove top, and all that you have to do is make a few minor and cost effective alterations to your equipment.
To start, it is recommended that you get a canning element for your stove top. The weight of a mostly-full, 30 litre (9 gallon) kettle can warp a regular element.
Second, you’re going to need to insulate your kettle in order to offset some of the heat loss from a stainless steal kettle. You can do that by using foil insulation. I used some aluminium tape and lined the bottom of the foil insulation to protect it from the heat and I made sure that the insulation was cut about 3 cm away from the bottom of the kettle. Be sure to take that precaution because the foil will melt if its too close to the element. Also, never use this method for gas stoves or any other open flame. For added protection, I also lined the inside of the insulation with aluminium foil for added protection.
With these adjustments, I was able to achieve a nice rolling boil as is required. You can see the results in the gallery below.
