 There's two types of findings, there's auxiliary findings and there are isinglass findings. Isinglass findings are basically, they're the main finding that will clear the beer. The auxiliary findings are something we add to the tank and they will help the clarifying process. They won't clarify the beer on their own, but they will just help to make it that more clear when we do add the isinglass. The isinglass are essentially swim bladders from Sturgeon, so it's a fish product if you like. We usually don't like to advertise that fact. And basically... Usually that's not left in the beer when you're drinking it? No, because what it does is that it drops the yeast out. So at the moment, we add the findings to the cask. The findings will cause the particles of yeast to come together and form larger flocculations if you like. So that's to do with the charges? That's to do with charges, yeah. The auxiliary is negatively charged and I think the isinglass are positively charged Or is it negatively charged? They are positively charged. They stick together and that then pulls down the sediment? That will pull down the yeast, yeah. So it will cause the yeast to come together. So the yeast will clump together and it will form larger flocs and in doing so it will then be able to drop out, exactly. So if I give this a shake, you'll see the yeast coming from the bottom and going back into suspension. So you can see there's kind of some reasonably large flocs there. Now they're only there because this has already been fined and been settled for a little while. If we take this one, for example, you can see this hasn't cleared yet. It'll probably take another three hours for this one to clear. So the yeast is still kind of forming larger flocculations and then dropping down. So really, it's a process of the yeast coming together and getting larger. And you can see the larger bits are already starting to fall down towards, by process of gravity, to the bottom of the findings bottle. And this is done partly because people want to clear beer? Exactly, yeah. So the yeast does affect the taste, they imagine? The yeast does affect the taste but largely this is because people want beer that's clear. They drink with their eyes as well.
