I am contemplating utilizing my Yeast Bed of wlp500 (Chimay) that is presently sitting beneath the Dubbel that was started on Nov. 19th. It is in a 9.5-10 gallon batch that is in a 15.5 gallon Sabco Fermenter. OG was 1.076 and as of a week and a half back or so (2 weeks and 2 days in primary) it was down to about 1.016-1.017, when I drained a sample through racking tube. I will be preparing another batch, one of a lighter color but not as strong as a Trippel to pour upon this Cake as opposed to harvesting, cleaning the whole Fermenter which is closed and hasn't been open since pitching the 3 liter starter from stir plate.
Now my question to You Brew Brainiacs, or anyone is.. does this sound like a plausible plan, and if so, any special preperatons like adding a Yeast Nutrient or an additional pitching from another starter from above. I was planning on getting the Ardennes strain of yeast into the Starter on the Stir Plate friday night, and count on a second wind from the Yeast Cake while it's in place. Is there any sense to this? I haven't brewed on a Cake in these Fermenters yet, and haven't done so with a higher gravity wort such as these at any rate. I will be racking the Dubbel off into secondaries either way friday night or saturday. Thanks!
