Daily citrus updates.
With a growing list of resources (see below) this will only become better and better. With better technology and extra options (translated news anyone?) you will really appreciate this.

A Private Global Citrus Community


The value we get back from good discussions is something we always realize when coming back from a conference, trade fair or other industry event. Bringing the stakeholders together and having these discussions within a private community makes it a valuable resource for everyone. And by having them asynchronous online, in a safe environment, pulls them beyond the borders of time and place, available for current and future members to read.


As there are many stakeholders in different areas of citrus expertise, groups will allow for more specific focused conversations. Whether it is on new robotics for picking in a new tech group, on HLB in a research group or on PEF preservation in a juice processing group... there will be space to find your peers and have in-depth discussions, or even take it to a next level:

Online events

The platform allows to have AMA's (Ask Me Anything live sessions) with key researchers, heads of industry or to organize smaller scale virtual events in a specific field of interest. So rather than focus on 1 or 2 major events per year, there is room for more continuous learning and diving into current developments.

Private Community Resources

Over the years I built a great collection of resources where to find citrus specific news and information. Opening it up to the citreae community will only further increase its value and allow for improvement and enrichment.

To give you an idea what you will find there:

  • Most growers and growers' associations in the main citrus producing regions of the world
  • Most citrus producers
  • Many of the companies directly or indirectly linked to the citrus industry
  • Universities with a special focus department on citrus
  • Regional organizations representing citrus growers and/or citrus industry
  • Online sources for citrus information

The Time Line

Pre-Launch [< December 31st 2020]

Full Launch [January 4th 2021]

With your participation the citreae platform can become the glue that brings all citrus stakeholders and all (future) generations together. In shared knowledge, through better connections and with a global mindset.

I really look forward facilitating this and seeing you actively engaged!

    🍊 Orange you glad? Well, I surely am!

    The notification that you bought a lifetime membership for citreae just sparked a small chain reaction:

    While the printer started printing the confirmation, its motion made the lime that was on top roll off of it. In a bizarre coincidence, it made its way towards a ruler that was balancing on Pierre Laszlo's "Citrus, a History."

    As the ruler swiveled on the book's side, it knocked over the empty bottle of Orangina which spun and slowly rolled towards the end of the desk. Seeing this happen in the corner of my eye, I was about to brace for impact when the bottle took an unexpected turn and came to a halt against the refractometer in front of the window.

    Because of the force of the impact, the refractometer shifted position and caught a ray of sunlight. A bright beam erupted from it and started to burn markings in the grapefruit next to it. As I slowly turned around, I couldn't believe my eyes. It must be a miracle, but the markings looked a darn lot like the never disclosed super secret formula for Coca-Cola...

    Unfortunately the peel oil in the grapefruit actually made it catch fire and destroyed all evidence right in front of me. Some lime and lemon oil ingredients were all I was able to decipher from the short moment I saw the formula...

    After cleaning up the lovely smelling mess I suddenly remembered what had caused all this.

    🍋 You are part of the next level of citreae! Brilliant!!

    I am super happy and excited because your commitment enforces mine. Thanks again and we will be touch soon.
