When brewing beer, it is very important to have a easily repeatable routine. Anything that makes the process easier can really improve the quality of your beer by decreasing the number of mistakes you make.
This grain and hops strainer is perfect for me and my setup because it can be added and removed from my brew kettle very easily.
3 inch PVC collar - $3
2 pack 5 gallon nylon paint strainer bags - $4
Hose clamp big enough to fit collar - $1
3/4 inch dowel $2
Drill or drill press
7/8 spade bit
Step 1: Not much to it
Using a 7/8 spade bit, drill two holes in the PVC collar about 1/2 inch from the top. Line the holes up on opposite sides as straight as possible.
And you're pretty much done. To assemble just slip the bag around the collar and tighten the hose clamp securely around the bag. The dowel rod will hold the bag over your brew kettle kind of like an over-sized tea bag.
