I just figured It had to be wheat and/or honey specific since all the other batches have solid yeast cakes on the bottom. I do the secondary specifically to harvest from primary. I'm leaning toward a rinsing issue. Honestly my yeast cake has been so clean and uniform that during the rinsing process I have been having a hard time determining the place to harvest from. I don't get a dark line forming like I used to. It all looks the same since I started using hop bags. I let it settle any where from 10 to 25 minutes and the very bottom will have some darker matter the top will be visually less floculant. Think I'll try as suggested:
with 001 especially, it's extremely beneficial to throw out just a little extra from the top portion.
Any videos or good photos on rinsing would help. I've seen some but everything look less uniform then what I'm getting from my fermentors. What about the top cropping method? Would it be better to top crop really clean yeast from the top and step it up on my stir plate?
Top cropping works, just another technique. I've done it exactly once, to see how it was done. Other than that I was more interested in the other aspects of the yeast, so I just ... didn't. Nothing against it though.
The yeast cake should be uniform in color. Any dark lines, as you noted, are from not-yeast. No longer getting a dark line means you're having good fermentations, properly getting rid of the trub & harvesting correctly. Try this, start using mason jars. They have more of a 'soup can' shape (as opposed to a tuna can). If you start using the same smaller vessels every time, you'll start to get a feel for what you need to rinse out. The jars aren't neccessary, but I find them easy to work with, clean, sanitize & measure my samples. Start by being extra paranoid & get rid of too much of the 'heads'. Collect a smaller sample. Most of the samples I collect need 2-3 step-ups before pitching. Occasionally more.
Sorry about the post, I'm still trying to wake up after that quadruple-shot of Nyquil last night.
