Just sampled the first bottle of my American Amber with CML US Pale yeast. Tasting great and nicely carbed after 13 days however the final 3rd of the bottle is a cloudy, yeasty mess at the moment! Hopefully that's just a a matter of time compacting it down.
This is the problem I had with the US pale - after 2 weeks in the bottle it was cloudy still. After 3 weeks, it's a lot better but I'm still having to leave a lot in the bottom of the bottle when pouring. The beer has now cleared very well though. Hopefully in another couple of weeks it will be a little more solid.
I read on their website that the US pale has similar characteristics to US-05 and some people find that that yeast flocculates a bit more than other yeasts too.
