Enhance Your Compost Tea Biology

Brewster Max is a specialist microbial enhancer developed for use in compost tea brewing, combining beneficial bacteria and fungi to support nutrient cycling, organic matter breakdown and a healthier rootzone.

Its synergistic microbial blend helps break down thatch and organic residues, release bound nutrients and encourage a more fungal-dominant rhizosphere — particularly valuable when managing fine perennial turf.

Used as part of a compost tea programme, Brewster Max helps strengthen biological activity in the soil and make better use of both naturally occurring and applied nutrients.

Key Benefits

  • Enhances compost tea performance – adds a targeted blend of beneficial bacteria and fungi to the brewing process.
  • Helps break down thatch and organic residues – supporting the biological degradation of cellulose and lignin-rich material.
  • Improves nutrient cycling – helps release bound phosphorus and trace minerals for plant uptake.
  • Encourages fungal dominance – supporting a rhizosphere suited to fine perennial grasses.
  • Supports microbial activity – complex carbohydrates provide an energy source for beneficial microorganisms.
  • Works with wider biological programmes – complements compost teas, organic inputs and sustainable turf management strategies.

How Brewster Max Works

A healthy turf rootzone depends on a diverse microbial community capable of breaking down organic matter and recycling nutrients.

The bacteria and fungi in Brewster Max help process organic residues and release nutrients that may otherwise remain unavailable within the soil. As organic matter is broken down and beneficial fungi establish, the programme can help create a more biologically active rhizosphere supporting stronger, more resilient turf.

Application

Application rate: Add 50g Brewster Max per hectare of compost tea preparation.

Mixing instructions:

Premix 50g Brewster Max in 5L of water before adding it to the compost tea brewer.

Add to Compost Tea Brewer (200 L to 800 L) after adding  ADD-apter &  OrganoFeast. Add 100 mls ADD-apter per 100 L of brewing water volume.
Add 500 ml OrganoFeast per 100 L of brewing water volume.
