Acro is the first personal malthouse. It's pilot malting equipment for accelerating the malting revolution. Acro automates the week long malting process, and consistently produces high-quality malt. Hook the machine up to water, power, and wifi, design a recipe in our webapp, add your grain, and you're ready to start malting.

Grain for use with your personal malthouse is available through Sprowt Labs if you don't have a local source. Please reach out through our contact page for information on how to order malting grains.
