As you start brewing more often and at larger volumes, you’ll inevitably begin to purchase grain by the sack. At that point, you’ll need a scale to weigh your grain and a storage container.
I have five of these air-tight containers to store my most used base grains.

The scale I use allows me to weigh up to 50 pounds of grain at a time. It has a detachable face, so I can have the bucket in one place and the display at a location better suited for reading.

I hope these couple quick tips help you in your continued brewing adventure!
