Perhaps that's two questions. But here's what I'm contemplating, and I'd appreciate any input. I prefer BIAB, because I've had just one too many stuck sparges and problems with false bottoms and manifolds. So I just put the bag in the mash tun and forego any sparges. But I've dedicated 2019 to exploring Belgian styles. I've already made a pretty nice Trappist Ale, and while I'll experiment more with the variations of the smaller Belgians, I also want to get my feet wet with Dubbels and Tripels. So here's my question. I figure I could not only save time and money, but also kind of make a Trappist a little more authentic by using later runnings from a larger Belgian. But I don't sparge with BIAB, so I was wondering if it's worth drawing off the runnings from the initial mash for a Dubbel, then essentially doing a sparge in the bag for 15 minutes or so, collecting that, and using it for a Trappist. With different hops and different yeast, the end result would be a different beer, instead of "Dubbel Lite." So ... is that an option? Also, I wouldn't be brewing both beers on the same day, so what would be a good way to store the wort from the sparge for, maybe a week?
