    <p>Coffee is more than a drink; it's a cultural symbol and cherished ritual worldwide. From Italian espresso to Turkish coffee and artisanal pour-overs, each culture has its unique approach. Whether enjoyed black or infused with milk, spices, or syrups, coffee's versatility is undeniable. It sustains millions of livelihoods, from farmers to baristas, and as we savor its rich flavors, coffee ignites joy, connection, and fuels our daily endeavors.</p>
