What is a grant?
A grant is a secondary vessel outside of the mash tun that controls, regulates and (in my case) filters the flow to the boil kettle.
Why use a grant?
Using a grant is a great tool when doing all grain brewing. First, its great for filtering. During your vorlauf you use this recirculation process to clear the runnings and to set the grain bed. With the addition of the grant, you are able to set filters in place to pick up any extra particles or husks. This also holds true when switching over to sparging. Typically the grain bed stays stable as long as your flow is consistent, but occasionally some junk can come through. Another great thing is the ability to control flow. Depending on your setup and where you place your grant, you can let gravity do the work! We can get more into the mechanics though later in this post.
