Total Fermaid O 16.00 g
Per gallon 3.20 g/gal
1/3 sugar break 1.067 SG

At pitch (0h)4.00 g
24 hours4.00 g
48 hours4.00 g
72 hours or 1/3 break4.00 g

This is a practical TOSNA-style estimate for Fermaid O. Stop nutrient additions once you pass the 1/3 sugar break, and always combine with temperature control, oxygenation in the early phase, and healthy yeast pitch rates.

Fermaid O reference bands

OG range Typical grams/gal Notes
1.060-1.080 1.9-2.6 g/gal Hydromel / lower gravity
1.085-1.105 2.7-3.6 g/gal Most traditional meads
1.110-1.130 3.8-4.6 g/gal Higher gravity, more stress
1.135+ 4.8-5.8 g/gal Strong meads, oxygen strategy matters

01

How to use this mead nutrient calculator

Enter batch size and OG, then choose light, balanced, or high-gravity mode. The calculator returns total grams plus a four-step schedule.

Use this as a process baseline and refine by fermentation speed, yeast behavior, and repeat readings.

02

How OG changes nutrient demand

Higher OG generally means greater yeast stress and higher nutrient demand. Lower OG meads usually need less.

Using OG directly keeps nutrient planning tied to real must strength instead of rough guesswork.

03

Use the 1/3 sugar break correctly

The 1/3 break is a common stop point for additions. Front-loading nutrients early supports yeast health in the most active phase.

Track this with gravity checks instead of time alone for cleaner execution.

04

Troubleshooting nutrient plans

If fermentation drags, review pitch rate, oxygen timing, and temperature along with nutrient totals.

If fermentation is too aggressive, reduce intensity next batch and compare results in your log.

FAQs

Frequently Asked Questions

Common mead nutrient planning questions.

Why does mead need nutrients?

Honey is low in yeast-assimilable nitrogen, so nutrients reduce stress and help cleaner fermentation.

What is the 1/3 sugar break?

It is a common point where nutrient additions stop to avoid late-stage off-character.

Can I use liters?

Yes, the calculator supports gallons and liters.

Does this replace oxygen management?

No. Nutrients, oxygen timing, temperature, and healthy pitch rates all matter.

Is this only for Fermaid O?

Yes, this version assumes a Fermaid O style schedule.

Should I change dose for high gravity?

High OG musts may need a higher schedule, which is why intensity mode is included.
