When flying on a plane, beverages and tea are typically offered during the journey. Each person has their own preferred drink – some like cola, some prefer juice, others may opt for wine, while some simply stick to mineral water. But why is a refreshing and bubbly ginger ale the top choice at 36,000 feet in the sky?
Ginger ale is a relatively mild beverage on the ground, originating in the 1940s in Ireland and the UK, quickly spreading across the Atlantic. John J. McLaughlin of Ontario founded Canada Dry in 1904, which remains one of the most renowned and popular dry ginger ale brands to this day. Its crisp taste, abundant bubbles, unique flavor, and color set it apart.
However, ginger ale brands have struggled to compete with the top 10 popular soda brands in the United States like Dr. Pepper, Mountain Dew, and of course, Coca-Cola dominating the market. But there’s one place in the world where ginger ale reigns supreme: the sky. But why?
Research has shown that taste buds slightly differ at high altitudes due to the dry air and cabin pressure weakening taste and smell senses. According to the World Health Organization, the dryness in airplane cabins is akin to being at an altitude of 6,000 to 8,000 feet.
Nutritionist Lauren Grosskopf, MSc, RD, explained that the impact is most significant on sweet and salty flavors due to the unique conditions in the cabin. Another reason taste may be harder to discern while flying is the low humidity in the cabin, causing beverages like coffee to taste more bitter, wine excessively acidic, and main dishes bland.
Dry ginger ale, compared to sweeter golden ales, tends to be more popular among the masses. In-flight, the additional sweetness of ginger ale may not be fully perceived by the taste buds, making it come across as exceptionally dry, crisp, and invigorating.
There are numerous benefits to drinking ginger ale at 30,000 feet in the air. Grosskopf mentioned that ginger, known for its medicinal properties, is particularly beneficial for travelers in relieving nausea, indigestion, and muscle pain, serving as an anti-inflammatory aid.
Most ginger ales are not made with real ginger but artificial flavorings, with the carbonation being one reason for soothing stomach discomfort. Opting for a ginger ale brand that contains real ginger would be a bonus for passengers.
Drinking ginger ale also helps travelers avoid common issues with carbonated beverages like diet soda at high altitudes, where bubbles take longer to dissipate. Ordering an iced diet soda is not advisable as it slows down the flight attendants’ serving process.
Beyond scientific or medical reasons, enjoying ginger ale is also an emotional pleasure. For those who regularly consume carbonated drinks, it becomes a habit without a clear explanation, forming an integral part of their routine.
