One thing for sure: the web content (web-sites) is largely underestimated. In fact, your web-site is the ultimate landing page for both professionals (somms, trade) and consumers. This is a place where people will look for your products and history, winemaking and background to understand what the winery offers.
With web-sites I consider the most important part to 1) deliver the necessary tone of voice 2) deliver specific useful information
What I do:
⇒ current web-site evaluation
⇒ new ideas generation
⇒ structure development
⇒ content creation (text)
