Water Flow Rate
It's very important to set your flow rate before you hook Acro up to water. Flow rates above 6
gpm (gallons/minute) will damage interior plumbing connections and cause water leaks or
flooding.
Acro requires a flow rate between 3 - 5 gpm. To set this, we recommend turning your hose or
faucet on and filling a vessel with a known volume of water while timing how long it takes to fill.
Malting with Acro
Recipes are designed in the web app on sprowtlabs.com. As we continue to build out our own
documentation, we recommend referring to the included book on Home Malting for recipe
design advice.
To start a batch from Acro:
1. Go to Malting -> Select Recipe -> 'Your Recipe'
2. Wash the grain before starting a steep. Go to Malting -> Wash Grain.
1. Acro will fill the vessel up with water several inches above the grain. Stir the grain
by hand or with a mash paddle to dislodge thins and chaff (malting loss) that will
float to the surface. Use a sieve to collect this malting loss and compost it.
2. Once you have removed all malting loss, go to Malting -> Vessel Drain.
3. Repeat this fill/drain cycle 1-2 more times, until you can easily see the grain
through the water, and no more malting loss is floating up.
3. Go to Malting -> Start Batch. Steeping will begin.
You can also schedule a Batch on the Web application:
1. Go to your App Dashboard (https://www.sprowtlabs.com/dashboard), and select a
recipe that you want to run.
2. On the recipe page, select "Start New Batch". This action will create a new batch page.
3. Schedule a batch, by clicking "Set Start Time", setting and confirming the time that you'd
like to start a batch. This is risk free. Delete our reschedule at any point. By scheduling a
