Apex Cultures® Amplify is a next-generation aroma-enhancing yeast nutrient designed to unlock maximum flavor expression in modern, hop-forward beers. Formulated with thiol-rich precursors, grape skin tannins, and advanced yeast derivatives, Amplify works synergistically with IRC-7-expressing yeast strains to intensify tropical fruit, citrus, and floral aromas while refining mouthfeel and overall flavor balance. By supporting yeast metabolism at critical stages of fermentation and dry hopping, Amplify delivers vibrant, expressive beers with greater freshness and sensory impact—efficiently and sustainably.
From a technical standpoint, Amplify supplies approximately 20 mg/L of yeast assimilable nitrogen (YAN) at a standard dosage of 40 g/hL, while also providing targeted amino acids, glutathione, and antioxidant compounds that enhance fermentation performance and flavor stability. Its formulation promotes the formation of key aroma compounds, including polyfunctional thiols (3-MH, 3-MHA, 4-MMP), esters, and terpenes, while helping to reduce oxidative byproducts such as aldehydes and ketones associated with beer aging. When applied in split additions during cold wort dosing and dry hopping or spunding, Amplify maximizes thiol release and aroma retention for a brighter, longer-lasting hop profile.
500 Gram
Grape skin tannins, yeast cell walls, autolysates of yeast, L-Ascorbic acid.
Maximizes yeast-driven aroma expression by supporting IRC-7-expressing strains and boosting the formation of active aroma compounds, enhancing tropical fruit, citrus, and floral character in hop-forward beers.
Promotes the formation of key fermentation aromatics by encouraging yeast metabolism of amino acids and aromatic precursors, leading to increased production of polyfunctional thiols (3-MH, 3-MHA, 4-MMP), esters, and terpenes.
Improves flavor stability and freshness through grape skin tannins and yeast derivatives naturally rich in targeted amino acids and glutathione, helping reduce aldehydes, ketones, and lactones associated with oxidation and beer aging.
Recommended dosage rate is 40 g/hl of cold wort/beer.
Add 20 g/hl of Apex Cultures® AMPLIFY directly into the cold wort, with an additional 20 g/hl during dry-hopping or beer spunding (at 2°P or ~8 SG points above the targeted final gravity).
It is essential to use brewing yeast that expresses the IRC-7 gene. This helps unlock and release the thiol precursors present in AMPLIFY and carry out the synergistic interaction with aromatic amino acids.
Store in cool dry place away from heat. On opening, use the product as quickly as possible. Packs which have been opened and part-used should be kept tightly sealed. If there are any signs of spoilage during storage of an opened bag do not use and discard the contents appropriately.
