So I've been brewing regularly for about 4 years now and have made probably over 50 batches and this recipe is one of my tried and trues and always turns out pretty well the exact same. its a 10g batch of pale ale, I usually use US05 but only had enough for 5g so I pitched that in one and I used an English ale yeast on the other 5g half... now I didn't mark it by any means but I believe the English ale finished in about 10 days which I bottled and I have the us05 which has been more like 25 days now and still looks like this- see below. It's hit its gravity target, tastes just like it's supposed to, it's about 20 Celsius where it's stored.. this is usually a very clear finishing beer. The English yeast finished perfectly-glass like clear- which is why I'm confused as they are both made from the same wort, any guess what happened?

What causes the persistent cloudiness is a really good question, especially after 25 days, even with US-05, which is a known slow flocculator.
Usually cold crashing for a few days with or without the help of gelatin or some other fining agent helps clearing the beer quite a bit more.

Did you pitch a fresh pack of US-05 or a repitch from a harvested cake? Anything else you did differently from the previous batches?
