What to do with mash after distilling?

Answered by Arthur Reyes

After distilling, the leftover mash, also known as spent grain, can be put to good use in a variety of ways. As an expert sommelier and brewer, I have explored various options and found that there are several practical and creative ways to utilize this byproduct.

One option is to feed the spent grain to animals. Farmers often use it as a nutritious feed for livestock such as cows, pigs, and chickens. The high fiber content and residual nutrients in the spent grain make it a valuable supplement to their diets. It's a sustainable and cost-effective way to provide additional nutrition for the animals, while also reducing waste.

Another great use for spent grain is in composting. Adding it to your compost pile can significantly enhance the nutrient content of the compost. The organic matter in the spent grain helps improve soil structure and promotes healthy microbial activity. This can result in richer and more fertile soil, which is essential for growing healthy plants and crops.

In fact, some farm distilleries go a step further and directly spread the spent grain over their fields. By doing so, they are able to recycle the nutrients from the grain back into the soil. This practice not only reduces waste but also provides a natural and sustainable source of fertilizer for their crops.

Interestingly, spent grain from production can also find its way into human consumption. In baking, spent grain can be incorporated into breads, cookies, and other baked goods. It adds a unique and nutty flavor while providing additional fiber and texture. I have personally experimented with using spent grain in bread recipes, and the results have been deliciously satisfying.

Furthermore, spent grain can be used to make spent grain flour. The grain is dried and then ground into a fine powder, which can be used as a substitute for regular flour in various recipes. Spent grain flour adds a distinct flavor profile and nutritional benefits to dishes, making it a great option for those seeking alternative flour options.

The possibilities for utilizing spent grain after distilling are diverse and exciting. Whether it's feeding animals, enriching compost, fertilizing fields, or incorporating it into our own diets, this byproduct of the process can be put to good use. As a sommelier and brewer, I find it incredibly satisfying to see how this once-wasted resource can be transformed into something valuable and beneficial for both the farm and the kitchen.
