Initial fermentation can be very fast. Check the hydrometer reading for a few days and if it is steady it is done. Taste the samples. If they taste good, you are probably good to package. Most of the time the samples will taste a little "green" and you will benefit from 2-3 weeks in the fermenter so the yeast can clean up after themselves and give you a better tasting brew.
No yeast, no beer. No beer, no civilization. Therefore, we really have yeast to thank for all our modern-day conveniences and tasty beer
