I would not know what to do with a partial grain recipe, as all I’ve ever brewed since my first batch is all grain. A stupid mantra of mine is work harder, not smarter. When I’m ready to brew a stout, I’ll look into a Samuel Smith homage - I do like that beer, a classic.
Funny you say that. I converted it for all-grain today. Completely forgot I'd done that until you said "all grain". Only one substitution, the grain malt for the LME. I still selected Pils, you can pick your favorite brand. You might tweak it a little to raise the ABV or the bitters, but take care not to cover up it's objective, the oatmeal and coffee and chocolate flavors. Alcohol will hide coffee flavors pretty quickly. Strong hops will hide the chocolate. Vanilla SHOULD enhance the chocolate, though, if I can believer the things I've been reading. There's always that dread of the batch that turns out to be pig swill.
Glad I'm better at making beer than I am at walking tightropes. Gives me a good reason to stay off 'em.
I'm going to agree that some of my all-grain batches have probably been far better than their extract look-alikes, but I also have to admit I've had the opposite results, too. My distributor is also a beer judge and tells me I'm wasting time with all-grain brewing but will happily sell all-grain to me if I tell him that's what I want. We have LOTS of 'discussions' about what I think I want to do. I'm firmly convinced I can't duplicate anything I do, no matter how well I document it, so why not try it a different way to see if I like it better? The partial extract method seems to get me close to the best of both worlds and is a lot less messy and time consuming than all-grain for the base malt. .The Rapier Wit I did today was 2 hours, start to finish. Hard to argue with the time cost when I've done the all-grain version and not found a noticable difference, The steep and sparge still take about the same amount of time for the flavors, but that's in a bag that can be snatched outta the strike that I just add the base malts and hops to in sequency. Then I drop the flavor grains in a colander, then pour sparge water over it. No mash tun needed, no hoses, no extra buckets. I take the bag out to the compost pile and feed the earthworms because there's not enough nutritional value in it to feed birds with. They fill up and still starve to death. According to bird people and some beer people. Armadillos love rooting around in it, for sure. Keeping the grist and the hops separated in muslin bags lets me easily separate the dog poison (hops) into the trash and away from neighbor's dogs. Since no hops ever actually touch the specialty grains, I don't worry about someone's dog ignoring leash laws and digging around in my compost pile (despite not ever putting any animal byproducts in it). NO dead dogs yet either.
I still do all-grain batches to see if I'm screwing up a good recipe with extracts. Typically, though, the only real problem I tend to notice is some darker coloration. I ain't making beer to win awards, other than the happy dance it makes my tongue do, so what do I care if it's a little too dark to win a contest?
