The instructions for the kit said between 5-7 days in the fermenter, and I read an article that said you should get the beer off the yeast cake as quick as possible.
Hence my change to 1 week ferment.
There's so many contrary opinions!
To be sure, I'm not at risk of infection if I leave it in the fermenter for another week after it's fermented am I ?
The instructions on the kit are not written by the brewing department but by the marketing department. Marketing department says homebrewing must be easy, otherwise people is discouraged. If you put too many instructions, caveats and precautions in it, people will run away from the kit screaming.
Don't pay attention to the instruction if you want the best quality your kit can give.
Don't use sugar, use dry malt extract (DME).
Don't count days, use a hydrometer or a refractometer and evaluate the advancing of the fermentation. The fermentation is completed when the density remains stable for 3 days.
Then, let the beer sit on the yeast for a few more days. It will clean because the yeast will begin using some substances as food which they initially discarded as not tasty enough (or actually which they vomited).
It's certainly not unheard of in my homebrewing experience to bottle after 1 months from preparation. Fermentations can have a "long tail".
After you bottle, wait a couple weeks for a proper carbonation at ambient temperature before putting the bottles in some cooler place (or colder).
Then leave the bottles undisturbed in the cooler place for a few weeks. The tastes will blend nicely. When the beer is green, I have a strange sensation of separation, as if the bitter in the beer doesn't make love with the sweetness in the beer.
Two-three months after the cooking is the normal and proper delay before enjoying your beer IMHO. Much less than that, and the beer is "green".
