I made a batch of mead at the beginning of March and I am getting ready to bottle it, but I notice a rubbery smell. Doing some research on the subject leads me to believe that perhaps I didn't have enough nutrients for the yeast and I have mercaptains in my mead (next time I will use yeast nutrient instead of raisins). Is there any way to fix this or do I just bottle it and wait? Thanks in advance for the input
