In addition to these practical considerations, the black line has cultural significance. It symbolizes the complexity and exquisite skill of beer technology. Black line is a strategic highlight of beer marketing, a symbol of brand stability and reliability, and also makes beer more luxurious and rich in texture.
Finally, the retention or removal of black lines in beer trademarks often depends on brand positioning and target consumer groups. High-end beer brands usually keep the black line, and civilian beer brands rarely use it. In any case, black line is an important element in beer trademark design and is deeply loved by consumers.
