The complex nutrient.

Purpose

Maxaferm® is a fermentation aid. It helps yeast by creating the conditions for complete, fast fermentation of the sugars in the must.

Maxaferm allows yeast to withstand difficult conditions (high temperature, release of toxic metabolites, high alcohol) and provides all the nutrients for growth and survival until the sugars are fully fermented.

Maxaferm helps produce wines with clean aromas and avoids the formation of undesirable metabolites such as SO2, H2S and volatile acids.

Science and technology

Maxaferm supports yeast by creating the conditions for complete, even and fast fermentation of the sugars in the must.

Кинетика на ферментация на Muscat à Petits Grains, преточен под 20 NTU и с под 150 mg/L усвоим азот. Метод без добавка в сравнение с добавка на 2 × 20 g/hL Maxaferm (24 часа след инокулацията и след това при плътност −50). Inter-Rhône, 2016 г.
Fermentation kinetics of Muscat à Petits Grains, racked below 20 NTU and with less than 150 mg/L assimilable nitrogen. Method without addition compared with 2 × 20 g/hL Maxaferm (24 hours after inoculation and then at density −50). Inter-Rhône, 2016.

Properties

Maxaferm:

  • corrects nitrogen deficiency in the must;
  • promotes cell growth and reduces sluggish and stuck fermentations;
  • helps yeast under difficult conditions such as low temperature, alcohol, grapes with Botrytis or powdery mildew;
  • ensures yeast vitality at the end of fermentation and thus complete sugar consumption, avoiding the risk of stuck fermentation.

Easy to use. Oenobrands products are made from yeast derivatives selected and dried using exclusive technology. This ensures rapid dispersion without lumps.

Composition

Maxaferm contains:

  • 60% yeast hulls. Their high ergosterol content maintains yeast membrane permeability and thus vitality as alcohol rises. The hulls also detoxify by adsorbing toxic metabolites, namely medium-chain fatty acids.
  • 39.96% diammonium phosphate. A source of assimilable nitrogen, needed for yeast cell multiplication.
  • 0.04% thiamine. Required for yeast metabolism and growth and for maintaining their ability to ferment sugars. It helps reduce the binding of SO2.

Dosage

  • Dose: 20–60 g/hL depending on the nitrogen content of the initial must.
  • Maximum (EU): 60 g/hL.
  • Maxaferm is added in two portions: 20 g/hL at inoculation and then 20–40 g/hL when one third of fermentation is reached.

Use

Suspend Maxaferm in 10 times its volume of water before adding.

If possible, use pumping over with aeration to stimulate yeast growth.

20 g/hL of Maxaferm provides 17 mg/L of assimilable nitrogen.

Packaging and storage

Pack sizes: 1 kg (hermetically sealed multi-layer laminated bags) · 10 kg (aluminium bag in a carton). Store in a cool, dry place (5–15 °C).
