Kolsch on a low floc yeast

G'day all - a question on brightness and clarity.

I've started fermenting a kolsch using Wyeast 1007, which doesn't floc easily. I intend to fix this by adding finings at the start of the conditioning - as I drop the temp it should help the solids fall out of suspension and into the trub. Am I on the right track here?

Edit: I should add this is mine and my brother's first go at an extract brew, after years of on-again off-again brewing out of cans.

You are correct that cold will help. When you think it is done fermenting, drop it down to around 0C (32F) and hold it there and that should drop out your yeast, plus most people feel that this kind of cold conditioning is beneficial for Kolsches. If you're kegging, then you are good to go. If you are bottle conditioning, then you might want to add back a small amount of yeast at bottling time.

You may not have to add finings if you drop the temp and cold crash it. There are many ways to clarify your beer:

Filtering possibly the fastest method
Fining using isinglass or similar to artificially flocculate the yeast
Cold crash drop the temp to about 2C/36F and the yeast will mostly drop out
Time and Gravity this is by far the slowest method but will eventually drop most yeast out of suspension.

If you need the beer clear in 3 days then add finings, if you have a month to condition then I would leave it for 25 days and if still not clear then add finings. You may find you don't need to.
