It is important to file the first trademark application with an eye towards future expansion.
In many countries, where World Wide Famous arguments are accepted, the first trademark registration becomes the basis for all future international trademark filings. It will be the guideline from which to file trademark applications in all future countries.
It establishes the date of first use internationally, a critical fact in trademark litigation. And it establishes the goods or services you were selling as of that initial date.
In some countries, a trademark registration from another country can be used to prove trademark usage, instead of actual sales in that country (such as in USA, but not so much in Canada). So in some countries, it is actually possible to file a trademark registration without yet doing business in that country.
So while you may be just starting out in your home country with your new product, that first trademark application should be made with an eye towards future worldwide growth. Consider your name, your goods/services, and the question of logo/font very carefully not only in terms of domestic sales, but international expansion as well.
The internet is a good way to pre-search your proposed new wine name in multiple countries at very low cost. For example, a very popular Australian wine that is exporting to European Union or USA will show up in an internet search if you put in your proposed wine name into Google or Yahoo. Dozens of international trademark offices have their trademark databases on line for free searching too.
Consider your brand name carefully, not only in terms of domestic sales, but international expansion as well. Consider what kinds of wines might eventually be added to your first offering. Consider if you want to be locked always into a single logo on every now and future label, in every single country ? Or not.
