For a 1 gallon batch of mead at medium gravity, Ive found roughly 2.5g of Fermaid-O works well. DAP sits around 0.75 teaspoons per gallon for the same scenario. High gravity batches above 1.110 OG push that closer to 4.5g Fermaid-O, which honestly surprised me.

Splitting into 3 or 4 staggered additions keeps fermentation cleaner.

Why Add Nutrients to Mead, Wine and Cider

What you are ready read does not come from some calculator or device. It is based on real discussions, forum discussions and practical experiences, that folks share in groups about brewing and fermentation through the whole net.

nutrient for fermentation is simply food for the fermentation itself. It delivers building blocks, that yeast truly needs to stay active; everything from nitrogen to vitamins, minerals and amino acids. One commonly finds it as a mix of diammonium phosphate (DAP for short) and food-grade urea.

That mix forms a setting, in that yeast stays healthy and active during the whole fermentation process.

Here the key spot: yeast does much more than simply produce alcohol and lumps. It grows, eats dead cells of yeast and releases hundreds of secondary compounds, that shape the taste and smell of your batch. From all that activity, yeast requires stable nutrition.

Free amino nitrogen, or FAN (is one of the key elements), that nutrient provides, and various strains of yeast require different levels from it. If FAN sinks too much, the yeast has troubles to grow. Then appear problems as blocked fermentation and bad sulfur compounds, that smell as rotten eggs.

A common example is honey. It has very little nitrogen, which shows, why mead-makers benifit a lot from adding nutrient.

The difference between batches with nutrient boost and those without it is truly striking. Studies point, that giving yeast nitrogen, amino acids and oxygen during the fermentation gives clearer and faster finish. Adding nutrient too mead, wine or cider helps yeast push forward and remove that bad sulfur.

Beer, on the other hand? It is an entirely other case. Barley malt arrives already filled with almost everything, what yeast truly wants.

Malt usually carries enough FAN, so that one does not always need extra nutrient for beer. The one spot, where beer malt sometimes lacks, is zinc. If you use dried yeast, truly, zinc maybe is the only addition, that you need, dried yeast already is rich in sterols and lipids.

Liquid yeast, on the other hand, likes additional supports as vitamins or mix with DAP.

When dealing about hard seltzer, hard kombucha, wine or cider, more nutrient beats no nutrient. Most folks use around one spoon each gallon. Following the advice on the packet works well.

Fermaid O and Go-Ferm got good names. Fermaid O does not speed up the fermentation pace, but it truly lifts the smell character of mead. Though, you will want to combine it with trace elements as Go-Ferm, because dried yeast or Fermaid K for liquid yeast give truly good results.

There is also a budget trick, that deserves a mention: boil baker’s yeast until it dies, and it becomes good base for nutrient. Dead yeast feeds the alive. Yeast husks act the same; they provide lipids and fat acids, that help the growth of new cells.

Beyond that, stressed yeast is a common cause of bad tastes. Giving yeast the right mix of nutrient, vitamins and minerals allows it to growstrongly and consume all those sugars in your malt, mead or juice.
