I bottled this up yesterday after crushing 4oz of coffee and tossing it in primary for three days. I didn't bag the coffee, just tossed it straight in. I used the muslin bag around the bottom of my autosiphon while transferring to the bottling bucket and it worked flawlessly. All the coffee was left behind and the siphon didn't clog at all.
I'm mildly concerned about this brew just because the smell/taste changed a lot since my first gravity check. I won't call it sour, but the flavors just seem a bit off. Granted, this is after coffee was added and there is a good amount of dark grain that needs time to mellow. Other than the slight off flavor, the coffee came through at the end very nicely. It's not as up-front as the Pipeline, but very good. I'll see how it is coming along starting in two weeks and then a bottle a week until it's ready.
