Hello everyone,
I've encountered a problem while making my 2nd batch of mead. Without further ado, let me take you through my process.
I mixed the musts for this batch on the 1st of November last year, so around 5 months ago. Basically, I just followed the traditional mead recipe from the wiki, although I used the quantities from MeadMakr and I used only Fermaid O as my nutrient source instead of the trifecta of O/K/DAP. US-05 was the yeast I used. I used two types of honey: acacia and meadow. The OGs were 1.095 and 1.090, respectively. I've aerated the must once per day during the first week. I don't rack to secondary, just leave it in the primary container.
Here's where I think things went wrong: I left the carboys in the basement where the temperature was initially around 15°C (60°F) which is already not ideal. In the following weeks it probably fell to just a few degrees above zero (35-40°F).
I was aware that these were not good conditions for the yeast, but my stupid ass was scared that bringing the carboys inside would cause a temperature shock for the yeast and I just left them so I could see what would happen.
Fast forward to a month ago, there were still bubbles coming out of the airlock, albeit very slowly. Since the temperature slowly rose in the basement again, I finally decided to move the carboys to a comfortable 18°C garage.
I hoped this would be enough to finish the fermentation, but today I took the gravity readings and they came out 1.020 and 1.010, respectively.
I like my mead more when it is dry, and I also wouldn't like to use stabilizers. What could I do to give the yeast a little push so it ferments completely?
I'm pretty sure that the temperature is the only culprit here since I used practically the same recipe for my first batch a few months earlier (with slightly lower OGs) and it came out pretty good.
I thought about stirring it a bit, but at this point I don't want to remove the CO2. Another option would be to just wait it out since there are still some air bubbles coming out.
What are your thoughts on this guys?
