It reduces heat spikes, promotes healthier yeast activity, and improves flavor profiles, making it the go-to choice for professional and home brewers seeking a cleaner, more natural fermentation process. ## Description Contains organic sources of nitrogen, not damp, along with nutrients for a healthy fermentation with less heat spikes. Better yeast health equals better flavors. Use 1.5G per gallon. Rehydrate in distilled water and add at 1/3 sugar depletion. Review: DAP out the window - So, I'm a big fan of doing things as naturally as possible and jumped at the chance to buy a yeast nutrient that comes from an organic source. I've used this several times previously to buying this and there is at least a very small difference in flavour in some (not all) of my side by side brew tests that I've used this in. When I use Fermaid O, there is an apparent lack of sulphite smell/flavour compared to using DAP or Fermaid K even in primary fermentation. That, and the fact that I know it's a natural product will be enough to keep me buying it (though I hope to find a decent UK source in future). This replaces DAP, Fermaid K etc. TIP: get this out of the packet and into a jar with a silica gel pack in it as Fermaid O has an insane affinity for moisture and becomes very sticky, very quickly!

Is it good for more than 2018? And does it require refrigeration, or just cool dark? Thx** A: Generally, we would recommend using the product within 12 months after opening. Refrigeration would be best, but is not required for storage. **Q: What is the difference between A & B?** A: AD332A has 12 grams of product while AD332B has 120 grams. **Q: Do you add an additional 1.5 grams at 1/3 depletion? Or are you splitting the 1.5 grams? Also do you add it immediately?** A: There are two schools of thought on this: 1. add at 24 hrs/48 hrs/72 hrs. Less specific than: 2. add at yeast pitch/25% depletion/33.3% depletion. YMMV **Q: Fermaid o is manufactured by lallemand, but this listing shows the manufacturer as "cellularscience". who is cellularscience? is this genuine?** A: I believe that Lallemand's smallest package size is 2.5kg. Cellularscience repackages the several products into smaller retail size packages. ## Customer Reviews ### ⭐⭐⭐⭐⭐ DAP out the window *by C***R on 23 January 2021* So, I'm a big fan of doing things as naturally as possible and jumped at the chance to buy a yeast nutrient that comes from an organic source.

Fermaid O improves the quality of my brew, and the value of that for the money is enough that I won't go without it. Pros: -The standard for organic yeast nutrition -Preferred over inorganic yeast nutrition -I feel it improves the taste and smell of what I ferment Cons: -People get riled up over using it or not Happy yeast make happy ferments; I keep my yeast happy by using Fermaid O. ## Frequently Bought Together - CellarScience - AD332B Fermaid O (120 g), 4.2 Ounce (Pack of 1) - Fermtech - Auto Siphon Mini with 6 Ft of Food Safe Tubing & Clamp - Easy Home Brewing, Winemaking Kit, Complete System for Beer, Wine, Liquid Transfer & Fermentation Tools - Perfect for Small Batches - Five Star - 6022b_ - Star San - 32 Ounce - High Foaming Sanitizer --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/80051154-ad332b-fermaid-o-120-g](https://www.desertcart.com.sa/products/80051154-ad332b-fermaid-o-120-g) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-07-06*
