What types of brewing techniques produce methanol?

The question is: What types of brewing techniques produce methanol?

Mashing is typically the moment where methanol production may occur. However, this is contingent on the kind of grains employed.

For instance, a significant amount of wheat malt can generate more methanol than barley malt. In addition, the time you devote to your mashing process affects the amount of methanol produced.

One of the primary ways your brewing process could generate methanol is through the pectinase-producing yeast, fungi, and bacteria. Pectin in your beer can produce methanol in your beverage but in tiny amounts comparable to wine.

If you’re not worried about making as much alcohol as possible and wish to lower the amount of methanol produced, don’t let your wort’s pH drop below 5.2 during this phase of the fermentation process.

One of the primary brewing methods that can trigger the production of methanol is distillation. Distillation may result in the production of high levels of methanol, which could cause harm to the body. This is why many nations have prohibited distillation at home.
