The question is: How can you tell whether you’ve produced Methanol?
Brewing does not usually produce any detectable amounts of methanol. This is because as it is not present in the form of pectins in your beer, you will most likely not have Methanol in the final beer. Pectins can be found in fruity beers; however, the amount of methanol produced is minimal.
One method to tell whether you’ve made Methanol is to use a Methanol test kit. It’s readily available at many beer stores. The procedure is simple: take a sample of your fermenter and add it to the test tube included in the kit.
The concentrations of methanol in beer can be assessed by measuring the pH of the beer you have fermented. Lower the pH will indicate a higher amount of methanol in the finished product.
