Brutus Ten
This Brewtus Ten was built completely from 2″x2″ steel square tubing based on Lonie’s original plans. Let’s face it, if we didn’t need it for brewing, we could always use it as a car stand. This brew stand was built to last.
From left to right, our Brewtus Ten beer brewing system consists of a boil kettle, mash tun, and hot liquor tank. All three of which were created from modified kegs with tig welded fittings.
The boil kettle is quite simple. It consisted of a ball valve, dip tub, and a mash screen. I just toss whole hops into the boil and the mash screen filters them out. (more…)

Mash Tun Return
There has been lots of discussion as to the proper placement of the temperature probe in the mash tun. In fact, it took me three different placements to find one that works well. I, like you, want my mash temperature to be as stable as possible.
My temperature probe location is at the top of the kettle nearest the actual mash return. I wanted to know the actual temperature of the wort that is being returned into the kettle and not the temperature of the grain bed. With this setup, I have been able to regulate the temperature of my mash within one degree which is confirmed by the lower thermometer.
The heart of my system is the BCS-460 which allows me numerous options. I constantly recirculate the wort through a pump during mash. The mash tun resides above a propane burner which is connected to a Honeywell brand gas valve. I am not a big fan of the ASCO system since it lacks safety features. The gas valve is controlled by the BCS-460 based on the readings from the temperature probe. (more…)

Thermowell in a Carboy
This article was written as follow-up to the previous article titled “Fermentation Temperature Control”. If you have any intent on duplicating a tasty beer, you need to have some process controls in place. Simple things can change your beer such as fermentation or mash temperatures. Let’s face it…. Most of us can crush the same amount of grains for the mash and add the same amount of hops to the boil.
If you ferment your beer inside a carboy, (or even a conical) a fermentation temperature control is easy to make. The picture to the left is a caboy with a sixteen inch stainless steel thermowell and an orange colored carboy hood. Two sizes of carboy hoods are available, one for a 6.5 gallon carboy and one for a 5.0 gallon carboy. The carboy hood comes with two attachments. One is used to connect a blow-off tube. Vnyl hoses size 3/8 and 1/2 inch work great. The other attachment port is for the thermowell. Slide the thermowell into the center most port. Make sure to purchase a flared thermowell so it completes the seal and acts as a stopper. It would make a person really unhappy if you pushed your thermowell all the way into the ”soon to be beer” because the end wasn’t flared.

Love Temperature Sensor
If you are familiar with the love temperature control, you know they come with a temperature probe. The temperature probe has a black rubber-likea coating on it. Depending on what thermowell you decide to purchase, the coating causes the temperature probe to be too thick to fit. To remedy this, I removed the coating from the temperature probe using a razor knife. I have not had any issues with the probe by removing the coating.
