What is one way a barista can improve their product knowledge?

Attending coffee tasting sessions is an effective way for a barista to enhance their product knowledge because these sessions provide hands-on experience with different coffee flavors, brewing methods, and ingredient interactions. During these tastings, baristas can learn how various factors such as origin, roast level, and preparation can affect the taste and quality of the coffee. This immersive environment allows for practical learning and the opportunity to ask questions and engage with knowledgeable peers or trainers, deepening their understanding of the products they serve.

In contrast, focusing only on popular drinks might limit a barista's understanding of the full range of offerings, while merely reading the menu does not foster a deep knowledge of the ingredients or preparation methods. Engaging customers about their preferences does provide insight into customer likes and dislikes but may not significantly enhance the barista's comprehensive understanding of the product itself.
