Us 05 produce that ?

Just about any yeast can, will produce more if fermented too cold. This is why you let your beer ride for a week after it is done with active fermentation. Yeast will clean that up.

You can do that, I never have. Time is your friend. There is nothing wrong with sampling while in the fermenter too. If it tastes like it isn't finished, give it a few more days

That's sounds logic, as i said I'm not brewing just for drink, im testing things, i know the basic
Every of flavour or infection i get it's a win for me, but it's a win if i known what happened and why, I will keep testing things, i must buy this off flavour kit its necessary , will help me a lot
