Super charge fermentation
Does an excellent job! I’ve added this Fermaid K to a couple gallons of must to brew Mead and in about 8 hours the fermentation took off in a supercharged style! I’ve attached a video of the active fermentation to prove it. At only 1 gram per gallon of must this stuff is definitely a “must”.

Great additive that does it's job well.
Straight up product with proven record. Fermaid K is what it is. This is the second time I've ordered this product and it's worked perfectly both times.

Great product
Used for rehydrating the yeast for a meade. Got the must down to 1.000 Final Gravity with healthy yeast

Good for citrus brews
Not needed in every brew. But, if a brew gets 'stuck' because of acidity or lack of nitrogen, fermaidK can save it.

my poor yeasties have been stressed
Hokey smokes! Been brewing old school for years, my poor yeasties have been stressed, and now that I am paying attention, the yeast are happier, my melomels are tastier, and as an added bonus, they do not need to sit in the carboys for months and months anymore.

The professional yeast nutrient
This is the go-to for many home brewers. I personally add a dose pre-fermentation and a second one on the fourth day. Be sure to mix it with water before adding it halfway through fermentation, otherwise, it will make your wash explode like a volcano.

I used some last night in a mead and the yeast seems very happy this morning
It is as expected. I have moved it to a zip lock bag for storage after opening it though. I used some last night in a mead and the yeast seems very happy this morning. Lot's of fast fermentation going on.
