What Is Potato Beer?

Potatoes can be found in more than just fries, hash browns, and baked varieties. Surprising as you may think, this nutritious comforting, and ever reliable potato is also distilled by some to become vodka of course and it is slowly gaining popularity with craft beer breweries because they use potatoes as a source of beer sugar for fermentation.

Potatoes have a long history that dates back as early as 8,000 to 5,000 BC when it was first cultivated by Inca Indians in Peru. It was brought to Europe by the Spanish Conquistadors during the mid-16th century by a man named Sir Walter Raleigh. Since then, the potatoes have been fried, baked, and mixed with other foods and it has become a staple food source for many. But how did it become an ingredient for making beer?

What Is Potato Beer

The Science of Potato Beer

According to science, almost any food that contains sugars, complex or simple, just like starch can be fermented to become beer. Potatoes, such as sweet potatoes and yams, have naturally high sugar content, has enough natural amylase enzymes, and has enough diastatic power. This means that they can convert their own starches to sugars without any additional processing.

Potato beer brewers use unprocessed potato flakes or raw potatoes in brewing beer. The percentage of protein that can be found in potato flakes is the same as the percentage that can be found in malted barley. This means that potatoes can contribute protein to your beer as much as malted barley does.

Raw potatoes are prepared before brewing, they are peeled, cut into small cubes, and boiled for about fifteen minutes. They are then dried, crushed or whip. The crushed potatoes are added to the foundation water then once it is perfectly mixed, it can be brewed just like a normal beer with some extra stirring.

This process will result in a neutral-flavored mash that has all the floral notes of the hops and become a beer. But take note that potato can dry out a beer but most of the time, it results in a quaffable and dry session ale. But despite the endless possibilities that the potatoes can be consumed, there are still kilos that got to waste every year. That’s why a Dutch company named Instock created a unique food-waste craft beer called the Pieper Beer with the help of an Amsterdam-based brewery. This beer is made from excess potatoes and it is a floral bitter taste that is similar to the Pale Ale.

Did you know that aside from potatoes, yam and sweet potatoes are also used in brewing beers. Their high sugar content contributes a lot of sugar in the beer which is used in fermentation. In fact, since the yam is famous during Thanksgiving, and the Americans recognized it’s flavor potential which resulted in brewing sweet potatoes as well. That’s why there’s quite a range of dark, pale, and craft potato beers that are popular today. And there are a lot of popular sweet potato beer brands that is in the market today such as:
