It is indeed possible to make vodka from sweet potatoes. In fact, there are several brands in the market today that produce sweet potato vodka. However, the process of making vodka from sweet potatoes is slightly different compared to traditional vodka made from grains like wheat or potatoes.
To begin with, sweet potatoes have a higher sugar content compared to regular potatoes, which makes them an ideal ingredient for vodka production. The first step in making sweet potato vodka is to convert the starches present in the sweet potatoes into fermentable sugars. This is done through a process called saccharification, where enzymes are added to break down the starches into sugars.
Once the sweet potatoes have been converted into sugars, they are then fermented using yeast. The yeast consumes the sugars and converts them into alcohol through the process of fermentation. It is important to note that finding the right yeast strain is crucial in sweet potato vodka production. Early versions of sweet potato vodkas required a significantly higher amount of sweet potatoes to produce a 750ml bottle, around 25 pounds. However, through experimentation and research, companies were able to find the right yeast pairing that could efficiently ferment the sugars, resulting in a more economically viable process. This also led to the development of a distinct flavor profile for sweet potato vodka.
Compared to traditional vodka made from grains, sweet potato vodka has a more earthy and nutty flavor. The sweetness of the potatoes also adds a subtle hint of sweetness to the final product. This unique flavor profile sets sweet potato vodka apart from other types of vodka and can be enjoyed on its own or used in various cocktails.
Personally, I have had the opportunity to taste a few different brands of sweet potato vodka, and I must say that I find the flavor quite intriguing. The earthy and nutty notes add a depth of character to the vodka, making it a delightful sipping experience. I have also experimented with using sweet potato vodka in cocktails, and it adds a unique twist to classic recipes. The hint of sweetness is a pleasant surprise and can complement a variety of flavors.
Making vodka from sweet potatoes is indeed possible and has become a popular choice among vodka enthusiasts. The process involves converting the starches in sweet potatoes into fermentable sugars, fermenting them with the right yeast strain, and distilling the resulting alcohol to create a flavorful and unique sweet potato vodka. So, if you're looking to try something different and explore new flavors, I highly recommend giving sweet potato vodka a try.
