Leiber-Boostar Range

Leiber-Boostar Range

Twice as clever!
What makes the Leiber-Boostar range so clever is the fact that it combines two key performance effects: firstly, the Booster effect at the start of the fermentation process, for rapid biosynthesis, and secondly, the ‘Star’ effect (‘Slow Target Release’) later in the fermentation process, which provides a balanced and high-yield source of raw materials for product formation and stress resistance – for example, in ethanol fermentation.

Applications

Dosage

Brewing beer

0.1 –   5.0 g/L

Benefits:

  • Increased viability of yeast cells
  • Improvement of the sensory profile
  • faster diacetyl degradation
  • Shortening the fermentation time
  • Increase in extract yield

Leiber-NutrYEA Range

Leiber-NutrYEA Range

A real game changer!
The newly developed Leiber-NutrYEA range, with its balanced components, provides a solution for many challenges! Leiber’s NutrYEA range contains exclusively vegan raw materials from Brewers’ Yeast and makes an important and lasting contribution to maintaining and boosting crop and soil health. From promoting stress resistance, with regard to external environmental factors, to improving soil health (microbes) or root and leaf activity; for use as seed coatings or even to control apple scab – Leiber’s NutrYEA range makes a real and valuable contribution to ecological and sustainable agriculture.

Benefits:

  • High content of many different amino acids
  • Improvement of abiotic stress resistance
