should I be worried about my orange-tinted limoncello?
I've had organic peels in vodka and Everclear for 60 days. The liquid isn't the bright yellow I anticipated -- it has a definite orange tint. I'm doing this in glass jars that don't have screw-on tops, and now I'm worried that was a bad idea.
What do you think? Just fine, or funked?
I'm relatively certain that nothing can grow in 190 proof ethanol; it seems unlikely that you have a bacterial problem or anything else that can cause you bodily harm if you ingest a sample. I think you need to smell and taste and let all of your senses decide whether you've produced orange drain cleaner or an interestingly-colored lemoncello.
Per what davis_sq_pro said below absolutely nothing could grow in that jar. Likely you are just seeing the natural pigments of the lemons change color slightly in the alcohol. Commercially made limoncello, even if all natural probably uses some special lemon-derived color, citric acid as a preservative, or oil to get that nice color.
