Which US cities have the driest air?

Answered by Bill Hernandez

As an expert sommelier and brewer, I have had the opportunity to travel across the United States and experience the varying climates and air qualities in different cities. When it comes to dry air, there are a few cities in the U.S. that stand out for their low humidity levels. Let me take you through some of these cities and share my personal experiences.

1. Las Vegas, Nevada: Las Vegas is known for its hot and arid climate, making it one of the driest cities in the United States. The desert-like conditions in this city result in very low humidity levels, which can be quite noticeable, especially during the summer months. As a brewer, I have found that the dry air in Las Vegas can have an impact on the fermentation process, as it accelerates the evaporation of from the brew, leading to higher content in the final product. Additionally, the dry air can affect the aging process of wines, as it can cause the corks to dry out more quickly.

2. Phoenix, Arizona: Another city with extremely dry air is Phoenix, Arizona. This desert city experiences very low humidity throughout the year, particularly during the summer when temperatures can soar above 100 degrees Fahrenheit. As a sommelier, I have found that the dry air in Phoenix can influence the perception of flavors. The lack of humidity can enhance the perception of tannins and acidity in wines, making them taste more pronounced. It's important to consider this when selecting wines to pair with food in such a dry climate.

3. Albuquerque, New Mexico: Nestled in the high desert of New Mexico, Albuquerque is known for its dry air and sunny weather. The low humidity levels in this city can be attributed to its location at a higher elevation and the arid climate of the surrounding desert. As a brewer, I have experienced the challenges of in such dry conditions. The low humidity can impact the mashing process, as the dry air can cause the grains to absorb moisture more quickly, leading to potential inconsistencies in the final product. Proper temperature and moisture control become even more crucial in such dry environments.

4. El Paso, Texas: El Paso, located in the westernmost tip of Texas, is another city with notably dry air. The region's desert climate and close proximity to the Chihuahuan Desert contribute to the aridity of the air in El Paso. As a sommelier, I have found that the dry air in El Paso can result in wines appearing more vibrant and aromatic. The lower humidity can enhance the perception of fruit flavors in wines, making them more pronounced and enjoyable.

Some of the driest cities in the United States include Las Vegas, Phoenix, Albuquerque, and El Paso. These cities, located in arid regions or desert environments, experience low humidity levels throughout the year. As a sommelier and brewer, I have personally witnessed the effects of dry air on wine flavors and brewing processes in these cities. The dry air can impact the perception of flavors, accelerate evaporation, and require careful temperature and moisture control in brewing. It's important to consider the unique qualities of the air in these cities when working with wines or brewing in such dry environments.
