After reading the wort should I put the sample back to e fermented
Nope! And clean the heck out of the dipper before putting it away.
Next Up: Superbowl Stout
Why not? And how do u get wart in test tube?
Should you? Your choice. You do risk infection. Is it worth that 2-3 ounces of beer? If you do decide to return it, clean and sanitize the wine thief and the hydrometer.
I don't think it is worth the risk, so I pour it into a glass and taste it.
Nope, i would drink it.
Most definitely drink it! I never met a sample I didn't drink.
On Tap: PTE Clone
Primary: House Pale Ale
I always just drop the hydrometer directly in the wort...
Is this a bad idea?
Heck yeah, use a thief that's been sanitized. I taste my batches every time.
