New to homebrew here. I have a NG hookup on my patio that I use for grilling. I would prefer to use NG instead of propane for brew day. Off-the-shelf or turnkey solutions seem to be hard to come by for natural gas brewing.

Can anyone point me in the right direction?

I'm going to be brewing with natural gas, but I went a different route. I picked up 3 10 tip burners.
The biggest issue with natural gas is the supply. If you are looking to just use 1 burner, your grill gas supply should be sufficient. If you want multiple burners or really high BTU burners, you will need a dedicated supply. Remember, natural gas burns with lower BTU's than propane when used in the same burner. If you get 50k BTU from a propane burner, converting it to natural gas will make it less.
If you have a banjo style burner, these are pretty much what you need to convert it to run NG.

I havent personally used them, so I cant say what burners they fit or dont fit, or if they work well.

Thanks for the heads up! I went ahead and just picked up a SP10 unit for now. I'll probably worry about NG more after I get my first brew started.
