That's a "kit and a kilo" kit? The no-boil, add a kg of extra fermentables, and then add yeast type of kit?
If so, then I'd let it sit 10-14 days before bottling (or putting in the pressure barrel).
One of the things that concerns me about those type of kits is that they often have you ferment way too warm (often above 20C) so it goes faster, but it causes some unpleasant flavors. Letting it sit longer may help that out.
