Modified Eicchorn-Lorenz

One of the early blogposts on this blog was called Eichhorn-Lorenz Grapevine Phenology. In 2018, I wrote a blogpost called Modified Eichhorn-Lorenz Grape Vine Phenology where I define what "phenology" is and also have a chart of the various phenological stages and the vineyard task that should be performed during that stage.
The modified Eicchorn-Lorenz chart can be found in an article in Wines&Vines called Grapevine Phenology Revisited.¹

In addition to tracking our Annual Cycle of Growth, knowing the grape vine phenology in more detail can be even more helpful. So, this year, I decided to breakdown the Modified Eicchorn-Lorenz chart into these major categories listed on the right hand side of the above illustration:

• Shoot and inflorescence development
• Flowering
• Berry formation
• Berry ripening
• Senescence

My hope is to take photos of the various stages and report back on this blog. Stay tuned.
