What is the reason brewing produces methanol?

The question: What is the reason brewing produces methanol?

In making malty beers, either none or small amounts of Methanol are created. Methanol produced by these sources is so tiny that it can be left entirely out. For instance, the hydrolysis process of naturally occurring pectin found in fruit beers can produce small amounts of methanol within your drink (wort).

The only way to generate methanol is if it utilizes malt extracts that contain enzymes that help convert carbohydrates into sugars. But, even this, the amounts are tiny enough not to influence the beer and your well-being.

Adding enzymes or grains into the wort in the mashing procedure can result in minimal methanol production. However, to put it in perspective, it is true that the quantity of methanol generated from these sources is so deficient that it can be left out.

Since homebrewing does not traditionally use Malt extracts, there ought to be no need to be concerned about producing small quantities of Methanol. So, homebrewers can continue to enjoy their passion without concerns about the dangers of producing this chemical.

How can we reduce the amount of Methanol produced from the brewing process?

There are many ways to limit Methanol production in making a beer. One of the most well-known is by boiling. Boiling reduces the conversion of reduced sugars to Acetaldehyde. It is then transformed into alcohol. This is also true for beers that have a high amount of adjuncts within their recipes.

Another way to cut down on the production of methanol is to use Brewers yeast strains cultivated so that they do not produce detectable amounts of methanol.

These kinds of yeast are offered by companies such as White Labs and Wyeast labs that supply a variety of Breweries in the commercial sector with their specific yeast requirements for their particular strains.

The last method to reduce the production of methanol is to make an application using an activated carbon filter after fermentation of your wine or beer.

An activated carbon filter eliminates organic and inorganic compounds. However, it targets organic compounds, such as methanol and dimethyl sulfur (DMS). This can be expensive for homebrewers because of the equipment required and the time required to filter.
