First Mead Questions

Started my first mead on Sunday.  15 lbs of wildflower honey, water, and 1/4 of the nutrients.  I rehydrated the yeast (71B-1122) according to package and I’m fermenting at 65 F.  I open and stir it twice a day, once in the morning and once at night.  I also add a 1/4 of the nutrients when I stir at night.  I currently have 1/4 left and from an interview with Curt Stock that I saw, he said the last 1/4 should be added when 2/3 fermentation was done.

My question now is how many more days should I be stirring the mead to off gas the CO2?  Is there some unwritten rule or it is based on percentage of fermentation completed?  Should I be stirring it everyday still but maybe not as vigorously as I have been?

I have some madagascar vanilla beans soaking in vodka right now to dose the mead at bottling time.

Thanks!

Not sure what my source is for this (NHC, podcast, mead induced dream?), but I of late degassing every day until about 50% fermentable consumed.  At that point you begin to worry about O2 doing harm.

I basically follow the steps in the link nateo posted in another topic. Here is the link…
