So when you are extacting wine with the wine thief to do your specific gravity testing do you:
<LI>Pour back into the carboy after testing(assuming of course your equipmenyt ewas previously sanitized properly)</LI>
<LI>Save in separate jar and add back later when you top off carboy (same note from above applies)</LI>
<LI>Don't risk contamination - consume or toss(maybe after a few batches I could learn something from the pre-tasting)</LI>
