North Mountain Supply Yeast Nutrient
North Mountain Supply offers a food-grade yeast nutrient packaged in a 3.5-ounce jar with a tamper-evident seal to ensure freshness. The formula combines diammonium phosphate (DAP) with food-grade urea, delivering readily available nitrogen to support yeast health and fermentation vigor. This product is described as a straightforward, reliable option for mead makers seeking a basic nutrient that supports robust fermentation without added complexity. Use at the start of fermentation to provide essential nutrients for yeast health and predictable attenuation.
Craft A Brew Mead Nutrient Bundle
This mead nutrient bundle from Craft A Brew is designed for larger batches, featuring Lalvin D47 Yeast for fermentation and a staged nutrient plan. The kit includes 10 packets of 5 g Day 1 Mead Yeast Nutrient, plus a 53 g Day 1 nutrient and a 66 g Day 2/Day 5 nutrient, supporting steady fermentation across a projected 10 gallons. The product emphasizes healthy fermentation, with a blend that includes Diammonium phosphate (DAP), Fermaid K, and potassium carbonate to address essential nitrogen and micronutrients.
Craft A Brew Mead Yeast Nutrient (Staggered)
The staggered formula from Craft A Brew provides Day 1 and Day 2/Day 5 nutrients to support larger batches and longer fermentation timelines. Like the bundle, it focuses on healthy fermentation by delivering a nutrient blend containing DAP, Fermaid K, and potassium carbonate. The staggered approach helps maintain yeast vitality at multiple fermentation stages, potentially reducing the risk of sluggish or stuck fermentations in mead production.
Fermaid O Yeast Nutrient
Fermaid O is a yeast-nutrient product that emphasizes yeast-derived components rich in organic nitrogen and vitamins, without inorganic nitrogen sources like DAP or urea. This 2-ounce package is marketed for use in wine, cider, mead, and kombucha at home. It is highlighted for its high YAN content and lipid components that support yeast health during rehydration. Fermaid O is positioned as a cleaner, more natural option for fermentations that aim to minimize inorganic nitrogen inputs while maintaining strong attenuation.
Fermax Yeast Nutrient, 1lb
Fermax Yeast Nutrient is a broader fermentation aid that improves attenuation and speed. Packaged in zip-lock style packaging for convenience, it’s intended for pre-pitch use to ensure yeast has adequate nutrition from the outset. The product is positioned as a versatile option for various fermentations, including mead, wine, and beer, offering a straightforward way to support yeast health with essential nutrients prior to pitching.
Craft A Brew Yeast Nutrient (Wine & Mead)
This 2-ounce package aims at elevating fermentation by combining food-grade urea and Diammonium phosphate (DAP). It’s designed to create a nutrient-rich environment that supports yeast health from the start of fermentation. The product emphasizes user-friendly dosing and its applicability to wine, mead, beer, and other fermentations that require steady nutrient supply and robust yeast performance.
Fermaid K Yeast Nutrient (8 oz)
Fermaid K is a blended complex yeast nutrient designed for musts and mashes used in alcohol fermentation. It supplies both inorganic nitrogen (DAP) and organic nitrogen (alpha-amino nitrogen), plus a suite of micronutrients and inactivated yeast. This combination supports balanced fermentation, reduces sluggishness, and helps ensure complete attenuation in mead productions. Fermaid K remains a standard choice for brewers and mead makers aiming for reliable yeast performance.
Buying Guide: Key Considerations For Choosing Mead Yeast Nutrients
When selecting a yeast nutrient for mead, consider nutrient type, fermentation goals, batch size, and desired flavor outcome. Here are important factors to guide your choice:
- Nitrogen Source: Decide between inorganic nitrogen (DAP, urea) and organic nitrogen (YAN) sources. Some mead makers prefer organic-only formulations to minimize potential off-flavors.
- Fermentation Timeline: For large or staggered batches, nutrient bundles that provide Day 1 and Day 2/Day 5 nutrients help maintain yeast health across fermentation stages.
- Batch Size: Ensure the product’s recommended yield matches your batch (for example, 5–10 gallons). Dosing guidelines should align with your projected volume.
- Additional Micronutrients: B vitamins, magnesium, folic acid, and biotin support yeast metabolism and sugar conversion. Look for products that include these components or a well-rounded micronutrient profile.
- Mead-Specific Formulations: Some nutrients are marketed specifically for mead; these often balance honey-derived must characteristics with yeast needs to promote clean fermentations and preserve honey flavors.
- Usability: Consider packaging size, resealability, and how easy the nutrient is to mix into must or wort without clumping.
- Reactivity With Must Composition: Honeys with high mineral content or specific honey varietals may benefit from tailored nutrient blends. If possible, consult batch notes or supplier guidance for adjustments.
In summary, the right yeast nutrient depends on your fermentation plan, batch size, and whether you prioritize organic nitrogen sources or a more traditional nutrient profile. For mead, staggered dosing and micronutrient balance can help avoid sluggish fermentations while preserving honey-derived flavors.
