Default wlp570 flocculation question

Hey all. I recently brewed a Duvel clone. I used wlp570 with a 1 liter starter for a 4 gallon batch. My OG was 1.078. It has been 10 days so far in the primary (brewed 9/18/10). I still have a fairly active airlock activity. I have never used a yeast that floccs so poorly. What should I expect for total time in the primary? I know that it will depend on my gravities, but will my FG arrive before flocculation completes? Will I need to crash cool to clear it up? Once I get my FG can I bottle with plenty of yeast in suspension to carb well and then just condition longer in the bottle? Any input on this would be very much appreciated. Thanks in advance!

I brewed with 570 on the 8th and your right. The krausen will take eternity to drop. I can tell you now that it is finally starting to clear after 3 weeks in the primary. I'm just going to let mine go for another week in the primary then bottle and age for 3 weeks. After that I'm just going to stick it in the fridge and let the yeast drop out that way. worked for me before when I used this strain.

Also, does a poorly flocculating yeast have less a chance of autolysis?

I'm not sure if or how flocculation affects autolysis. I wouldn't worry about it though. I always leave my beer in the primary anywhere from 3-6 weeks and have never had any problems. There are many people that do the same and if anything the beer will turn out better when you keep it in the primary longer. This is one of many threads that really helped me sort out this whole autolysis, primary vs. secondary thing: http://www.homebrewtalk.com/f163/secondary-not-john-palmer-jamil-zainasheff-weigh-176837/

My reason for asking this is that I read on another thread that somebody used this yeast and his gravity dropped 20 points in 4 months in the secondary. Should I prepare for something like that? I am not super keen on keeping my beer on the trub for 4-5 months. 4-6 weeks doesn't bother me one bit. I'm just wondering if that will be enough time for this yeast to attenuate and begin flocculation in addition to get to terminal gravity. That is my concern. Is 2 months on the trub too long, or is it necessary with wlp570? Beyond that, will I need a significantly longer fermentation time so that secondary will, arguably, be necessary? Granted, I know that I have not rechecked my gravities and that will be a far better indicator as to how close I actually am to bottling time, but just looking for a heads up. Thanks again.

OK, so this whole thing made me think, what the hay, why not just stop typing and check your gravity fool! So, the result is 1.010. Again, still airlock activity. And to boot, my est. final gravity was 1.017. So since I've already overshot it, should I just bottle, or should I let things roll for a little while longer?

Take gravity readings on three successive days (or, if you can wait, wait an extra day between each reading) to be sure it's not moving. If it's still dropping, you risk bottle bombs.

It's very possible you'll get lower than 1.010. I just bottled a 1.086 OG Belgian finish at 1.005. It was in the primary for 5 weeks.

Did it end up with a ton of estery bite? Which yeast did you use?

It's still very green, so it had some bite to it, but was generally tasty.

I used cultured Delirium Tremens dregs, which (from what I've read) are approximately equivalent to WLP550+WLP570.

Does anyone have anything else that they would like to add about wlp 570 or any other low flocculating yeasts behavior, ect? I needs the learnin'.
