Diacetyl problem

[Deevotronics]

So the natural temp never got high enough to give a good diacetyl rest. Im now stuck with a batch of pilsner that has a butterscotch flavour. Already lagered and run through keg to keg 1 micron filter and carbonated. Is there a way to get rid of this sweetness?

Warm it up, add a bit of sugar and pitch some fresh yeast.

Make an active yeast starter with some malt and healthy yeast. Add that. Raise temp.

Why did you filter and keg when it tasted like butterscotch by the way? Taste your beer before packaging, assess whether it's actually ready.

Missus birthday on saturday so rushed it a bit... rookie mistake. Didnt taste, trusted the nose. Will give the yeast a crack, thanks for the advice guys.
