Yeah, that's an alternative. I do some extract base stuff which lets me bag the flavoring/coloring grains in muslin, and it sure is convenient to just mix the extracts into the kettle after lifting the grains out. Solves the problem with the rinse on the kettle, but that really isn't too bad. I'm outside anyway with all-grain recipes and most extracts too, so I just take the water hose to the kettle after mashing. It's gonna get hot again, so I don't worry much about sanitizing. I sorta use that time for first wort hopping, too. I drop the bittering hops in the hot wort after sparge and cover the bucket until I get the kettle rinsed out again. It didn't even offer to boil over doing that on this latest batch, and this recipe is one of the worst because of large hop doses. Still gotta dry hop it too. It's a Kona Big Wave imitation. That's some yummy stuff, especially after a hot day in the yard.
My kettle is an 8 gallon stainless kettle. The only thing I can snag a bag on it is the probe on the thermometer which isn't sharp, IF I don't use the torpedo screen. I've ripped a few muslin hop bags open on that because of some stray wires from the screen that I can't seem to remedy. BIAB is probably a much cheaper option, too. Guess I'll see what's available and get some ordered. Any recommendations? I'm guessing 12 pounds of grain (my biggest beer) won't be too stupid heavy. What, 25 lbs or so with absorbed water? If I can carry a full fermenter (5.5 gal), I should be able to lift the bag outta the kettle. I can probably fab up a good rack to sit the bag on for draining, or a hanger of some sort that sits on top of the kettle and attaches to the handles. My monster burner is pretty stable, especially with the weight of the kettle and its contents, so I don't think I'd have to worry too much about it tipping.
