North Mountain Supply Fermaid O yeast nutrient in a 2 oz jar, formulated as an organic nitrogen source to nourish yeast, improve aromas and give better control over fermentation. It helps lower peak fermentation temperatures, improves late stage fermentation kinetics and reduces sulfur off odors such as H2S in beer and wine.
North Mountain Supply Fermaid O is a focused yeast nutrient designed for homebrewers and winemakers who want healthy fermentations and clean, consistent results. Supplied in a compact 2 oz plastic jar, it is a convenient size for smaller batch makers or for those who want to try Fermaid O as part of a more advanced nutrient program.
Fermaid O provides organic nitrogen and other key nutrients that support yeast health throughout fermentation. By supplying these components in a balanced form, it helps yeast perform more efficiently, which can lead to:
Cleaner, more focused aroma and flavor
More predictable fermentation progress
Reduced risk of sluggish or stuck fermentations
One of the main benefits of Fermaid O is its effect on fermentation behavior. When used correctly, it can help lower peak fermentation temperatures and improve fermentation kinetics, especially toward the end of the ferment. This can result in fewer sulfur based off odors, including hydrogen sulfide (H2S), which can be difficult to correct later.
Fermaid O is suitable for a wide range of beer and wine styles, from delicate white wines and fruit wines to robust reds and higher gravity ales. It integrates well with staggered nutrient addition schedules or other yeast management strategies designed to keep yeast healthy from pitch through to final gravity.
For best results, suspend Fermaid O in water or juice or must and mix well before adding it to your ferment. This is particularly important when adding nutrient during active fermentation, as it helps prevent sudden CO2 release and potential foaming or overflow in the fermenter. Always follow dosage recommendations appropriate to your batch size, style and process.
