I would suggest staying away from fermax. The thing you are trying to accomplish here is feeding a very specific amount of nitrogen to your yeast when they need it. The problem with so many rebranded food sources is you don't know what's in it. Or at least not what quantity. One of the things in most of this stuff is DAP. It has been used for a very long time along with Fermaid-K. DAP is inorganic nitrogen and cannot be assimilated once the yeast reach 9% ABV. If you add it after that it doesn't get eaten and leaves a crappy taste behind. Mix some in some water and taste it. It's not something I want in my flavor profile. Some of what is wrong in my estimation is it causes the yeast to enter into a frenzied state. This causes over population of the bio mass early on. It causes temperature spikes. It leaves a salty/chemical taste behind. It is regulated with limits on how much can be used in a professional setting. Many here use it in quantities that exceed the government requirements. At mead competitions that is a common fault found by judges.
There is a large portion of mazers here who are in the camp of feeding their yeast way past the point that the suits that work for the yeast manufacturers say is sufficient. If you feed at pitch, 1/3,2/3 sugar break you are feeding past what the PHD's say you should. In my opinion this is bad practice if you are feeding food with DAP in it. Fermax has DAP in it and you will have left enough behind to flavor your finished profile with it. Fermaid-K has some DAP in it as well I believe. Although I could be wrong here as I haven't used it in over a year.
One of the reasons this was started I believe, was to insure a finished fermentation in hopes of not having a stall on your hands. Many, or most that use dry yeast rehydrate with Go-ferm. Some of us saturate with an O2 stone. Some are finally starting to use the proper amount of PPM of yeast based on their gravity. By doing all these things correctly, also to include temp management, it's pretty hard these days to see a fermentation stall. I personally have not ever had one stall. With these precautions ( or what I see as good fermentation practices) it's pretty much expected that the yeast will finish very strong and go beyond the listed ABV tolorences listed in the manuals. Even when the added nutrient additions are all placed much earlier on than the 1/3,2/3 club.
Everyone I know that uses Go-ferm/Fermaid-O with dry yeast proclaims their meads have never been better. Fermaid -O is all natural and by default has all the things yeast need including the micro nutrients that are found in Fermaid-K. All of the professionals I talk with are also using this method and everyone now thinks that great mead can be packaged in 3 months time. This has been my experience as well although I choose to bulk age for a year or so before I bottle. I can do this because I have 150 gallons worth of carboys sitting around full and many other still empty waiting for the weather to turn towards cooler temps.
If I were not able to have this capacity to age it would be easy to bottle in 3-4 months for most of what I make. Obviously some things take a while longer to integrate and or for the higher alcohol to round out some. I know there are many ways to skin a cat. Mead is so resilient that it seems that time can heal anything. I'm sure lots of great mead gets made using all kinds of processes. I'm all for each his own. But, I feel so strongly about some things I want to say to all to try something new if you haven't. It works. It works fabulously in fact!
I'm constantly trying different things. Always trying to make a better mouse trap. Always open to other things. With that said I doubt we will see the same kinds of advancements in mead making in a very long time like we have seen in the time I have been making mead. I see the past year as the kind of gap that lies between analog and digital. Bronze and iron. Black and white TV.
This may very well be one of the best threads we have in this forum.
