if you only sell wine once in a while and don't plan to become bigger and stronger, you can sell it without a registered trademark, but whether anyone buys it or not is another matter! If you want to form a scale and establish a brand of your own, it is necessary to register a trademark. After all, most people will choose to believe in the power of the brand. If you have a good trademark, it is recommended to apply for registration in advance and plan ahead! Small trademarks are of great use! ! Hope to adopt! ! !
