Currently fermenting an American Wheat ale (extract) only using primary. 1) When should I start to check OG?
2) OK to use auto syphon to get the beer out to check (turkey baster won't fit into the carboy)?
3) OK to drink my sample?
4) once it has hit the target OG is there any point in keeping in the fermentor any longer?
Just to be clear, if it is in the fermentor you will be checking for FG (final gravity) OG is measured when it goes into the fermentor (Original Gravity) and is the starting point. FG is the ending point.
2.) Yes, just make sure it is sterilized.
4.) Yes, but depends on yeast strain. Once FG is reached the yeast can still clean up some off flavors, that is where the tasting comes in.
