Portobello mushrooms (Agaricus bisporus) are renowned for their large caps, dense texture, and rich umami flavour. As the mature stage of the common button mushroom, Portobellos offer a more developed taste and substantial texture, making them one of the most widely consumed mushrooms globally.
This species is well suited to cultivation on compost-based substrates and has become a staple mushroom for growers ranging from hobbyists to commercial producers.
Liquid culture is a nutrient-rich solution made from distilled water and carefully selected carbohydrates such as light malt extract, dextrose, or honey. These nutrients provide an ideal environment for mycelial growth and expansion.
The mycelium suspended within the liquid culture acts as a living inoculant that can be used to inoculate a grow kit, grain spawn, or suitable substrate. Liquid culture is often preferred because it allows rapid colonisation, efficient expansion, and reliable mycelial growth.
For optimal viability and vigorous growth, use your Portobello liquid culture as soon as possible after receipt.
If immediate inoculation is not possible:
Store the sealed syringe in a refrigerator at 2–4°C
Do not freeze
Best used within 3 months of receipt
