The beer that keeps on giving

Tried something new with my beers.  I brewed up a Strong Oatmeal Stout then sourmashed the spent grains for a second beer.  I put the blowoff from the Oatmeal Stout into one port of my carboy cap on the sour beer and let the krauzen transfer at will in hopes that it would kick off the second beer.  I knew it succeeded when I came downstairs to find the airlock on the sour beer full of krausen.  So not only did the Oatmeal Stout provide the grains for the second beer, the leftover hops from the packets, the extra oatmeal from the package, but it also provided the yeasties!  Not bad for $2 extra in ingredients.  And because my sour beers are typically 48 hours after the first beer, this method could be used for most of them.

So if you are keeping tracked, in the sour beer we have Partigyle, sour mash, and top cropping.

  1. That’s a pretty sweet little top-cropping setup you have going there!


  2. Actually, the photos are from after. To top crop, I just put the blowoff tube out from the Stout into the smaller port in the carboy cap. I put a couple of blocks to elevate the Stout carboy enough that the krausen would travel through the hose to the lower carboy. What you see in the picture is my blowoff bucket attached to both beers now.
