WESTWAY STC-1000 Temperature Controller / Dual Temperature Regulator
Temperature-controlled fermenting will drastically improve your brewing. Changes in temperature and high temperatures will most likely alter and affect your beer taste creating off-flavors or at worst will kill or injure your yeast – halting fermentation. Our Australian Summers as we all know get up to a painful 40°C, which is terrible for fermenting anything uncontrolled. When you most want a nice, crisp lager it will be at its hardest to ferment. You can try make it in Winter, but you will still have to store it cold for a reasonable amount of time. Essentially, if you want to start controlling the quality of your beer you absolutely have to start with temperature. Our Westway Dual-temperature controller is the perfect utility for all these such problems. All you need next is a cheap freezer or fridge to cool, or a heating element to warm. After that you will have a huge amount of control over the fermentation. You will be able to raise the temperature for diacetyl reabsorption and you will be able to drop the temperature to cold-crash kegs, or store and mature beer.
Soon you will be pouring clean and crisp lagers in the peak heat of summer.
Heat is the oft-overlooked byproduct of yeast fermentation; CO2 and alcohol are admittedly the most fun. But a too-warm fermentation means running the risk of unwanted esters (fruity aromas) and fusel alcohols (acetone, for example). Yeast strains have their own personality, figuring out how to maximize their strengths is a common topic of discussion at homebrew shops around the country.
Lager yeasts are routinely fermented between 40–54 °F (4–12 ºC) while ale yeast is used from 55–70 °F (13–21 ºC). The optimal fermenting temperatures of yeast vary considerably.
Some ale yeasts for example, do not perform well below 65 °F (18 ºC). The Narragansett (Chico) strain is notorious for this, as well as certain Belgian and wheat beer strains. Fermenting too cold results in stuck fermentations, poor attenuation (high finishing gravities) and off-flavors — especially diacetyl.
If you want to ferment cold, it will be necessary to acclimate your starter to a lower temperature to prevent cold shocking them. Do this by slowly lowering the temperature of the starter the day before.
Set the required temperature
Press “S” and hold until “F1” Appears
Release and then press “S” and at the same time press the up or down arrow to change the temp setting to the desired temp.
The controller will turn on the cooler or heater according to whether the existing temperature is higher or lower than the required set temperature.
