VitiSynth is a database and forum, described on its What Is VitiSynth? page as:

• A highly time efficient way for busy viticulturists, oenologists, vineyard managers, consultants, students, researchers and enthusiasts to keep up to date with the latest viticulture and wine research and practice from around the world;
• A place to start/join Discussions on very specific topics, ask questions and provide answers;
• A highly structured, precise database with unique search functions based on Interactions between Factors;
• Open access and therefore free of charge.

VitiSynth has the following components:

• Reviews- of current viticulture and wine research from around the world including Key statements, James' review, Practical implications and Read recommendations. 
• Synths- James' insights into specific viticulture and wine topics. Over time the Synths will form an online, up to date textbook covering a massive range of very specific topics. The beauty of this approach is that the "textbook" will be very well structured and highly searchable via VitiSynth. 
• Discussions- Each Synth has a discussion (forum) where you can discuss with James and all of the other users the specific topic addressed in the Synth. As a Registered user you have the opportunity to discuss topics that are important to you with people from all over the world. You can even request the establishment of a new Synth.
• The database- a unique Interactions database utilising highly precise and consistent Factors. You can use the Advanced Interaction Search to find specific information (Reviews, Synths, specific Interactions, Select Cultivars or Rootstocks by Phenology etc.) by selecting factors to various levels of specificity.
