Harvesting and Maturation

Harvesting and Storing Fresh Portobello Mushrooms

Understanding the growth stages and harvesting practices of mushrooms is essential for differentiating white mushrooms from their mature counterparts, portobello mushrooms. They share the same scientific classification but are harvested at different times in their life cycle.

Growth Stages

When you start with a common species like Agaricus bisporus, you are dealing with mushrooms that can be harvested at various stages of their development. White mushrooms, also known as button mushrooms, are the youngest version of this species. They are picked when they are small, with tightly closed caps and underdeveloped gills. As they age, they grow into cremini mushrooms, or baby bellas, which have a slightly browner color and are picked when they are medium-sized and their gills have barely started to show. If you allow these mushrooms to mature further, they become portobello mushrooms, characterized by their large size, thick caps, and fully exposed, dark brown gills.

Harvesting time typically spans from several weeks to a few months post-cultivation, depending on the desired maturity for either white mushrooms or portobellos.

Harvesting Practices

You should note that the differences in harvesting white mushrooms and portobello mushrooms are tied to their age and required conditions. White mushrooms are harvested early and thus retain a higher moisture content, while portobello mushrooms, which are harvested later, have less moisture due to more extended growth and evaporation.

Proper harvesting of white mushrooms involves gently twisting them from the mycelium when they reach the desired size, ensuring that the surrounding mushrooms are not disturbed. For portobellos, wait until the cap has fully opened and the gills are visible before harvesting. Portobellos can be removed by cutting them from the stem to avoid soil contamination and preserve the rest of the mycelial network. It is important for you to maintain careful handling of both types to prevent bruising and to ensure a quality product.

Proper humidity levels are crucial throughout the entire growth cycle, but especially so during the transition from baby bella to portobello mushrooms, as it influences both the quality and size of the harvest.
