Home brewers often treat the leftover spent grains as a
waste product. Can you compost spent grains? The good news is yes, but you need
to manage the compost carefully to avoid a smelly mess. Home brew composting
can be done in a bin, pile or even vermicomposter, but you must make sure the
nitrogen rich mess is managed with plenty of carbon.
Can You Compost Spent Grains?
Composting home brew waste is just one more way you can
personally reduce waste and reuse something that is no longer useful for its
previous purpose. That wet mass of grain is organic and from the land, which
means it can be sent back into the soil. You can take something that once was
rubbish and turn it into black gold for the garden.
Your beer is made, and now it’s time to clean up the brewing
space. Well, before you can even sample that batch, the cooked barley, wheat or
combination of grains will need to be disposed of. You can choose to throw it
in the garbage or you can utilize it in the garden.
Spent grain composting is being done on a larger scale by
big breweries. In the home garden, it can be used in several ways. You can
place it in a standard compost
bin or pile, a worm
composter, or go the easy way and spread it over empty vegetable beds and
then work it into the soil. This lazy man’s method should be accompanied by
some nice dry leaf litter, shredded newspaper, or other carbon or
“dry” source.
Cautions on Composting Home Brew Waste
Those spent grains will release a lot of nitrogen and are
considered “hot” items for the compost bin. Without plenty of
aeration and a balancing amount of a dry carbon source, wet grains are going to
become a smelly mess. The breakdown of the grains releases compounds that can
get quite stinky, but you can prevent this making sure the composting materials
are well aerated and aerobic.
In the absence of enough oxygen entering the pile, a buildup
of noxious odors occurs that will drive away most of your neighbors. Add brown,
dry organic items such as wood shavings, leaf litter, shredded paper, or even
ripped up toilet tissue rolls. Inoculate new compost piles with some garden
soil to help spread microorganisms to help speed up the composting process.
Other Methods of Spent Grain Composting
Large brewers have gotten quite creative in re-purposing the
spent grains. Many turn it into mushroom
compost and grow delicious fungi. While not strictly composting, the grain
can be used in other ways, too.
Many growers turn it into dog treats, and some adventurous
sorts make various types of nutty breads from the grain.
Home brew composting will return that precious nitrogen back
into your soil, but if it isn’t a process you are comfortable with, you can
also just dig trenches in soil, pour the stuff in, cover with soil, and let the
worms take it off your hands.
