So high that people die trying to get to the peak.
Could you safely brew a beer at the top of the mountain?
I have no idea.
But did you know that the altitude at which beer is brewed can affect the quality of your beer?
One of the key factors that are affected by altitude is the boiling point of water.
At sea level, water boils at 100°C (212°F), but at higher elevations, the air pressure is lower, and the boiling point is correspondingly lower. This means that the temperature required to boil the wort during the brewing process is lower at higher altitudes, and the boiling time needs to be adjusted to compensate for this.
But who can complain about your brew day being a little bit longer eh?
When wort is boiled, it undergoes a series of chemical reactions that help to break down complex sugars into simpler ones, and also cause the precipitation of certain proteins and the isomerization of hop acids.
If the boiling temperature is too low or the boiling time is insufficient, these reactions may not occur to the same extent, leading to differences in the flavor, aroma, and color of the finished beer.
In addition to affecting the boiling process, altitude can also affect yeast metabolism and fermentation.
In addition to affecting the boiling process, altitude can also affect yeast metabolism and fermentation.
The yeast requires oxygen for their growth and metabolism, and at higher elevations, the concentration of oxygen in the air is lower.
This can make it more difficult for yeast to function optimally, potentially leading to differences in the fermentation rate and the flavors produced by the yeast during fermentation.
The mineral content of water is another important factor that can affect the taste of beer, and this can vary depending on the source of the water.

At higher altitudes, water sources may be different, and the mineral content of the water may be different as well. Brewers may need to adjust their water chemistry to account for these differences, or even consider using different water sources altogether.
There are a number of beers that are brewed at high altitudes around the world. Here are a few examples:
- Cusqueña Beer: This beer is brewed at an altitude of 11,152 feet (3,399 meters) in Cusco, Peru. The high altitude reportedly gives the beer a lighter, crisper taste than beers brewed at lower elevations.
- High Altitude Brewing Company: This brewery is located in the mountain town of Gunnison, Colorado, at an altitude of 7,703 feet (2,348 meters). They specialize in a range of craft beers, including a Belgian Dubbel and a West Coast-style IPA.
- Sankt Gallen Brewery: This Japanese brewery is located in the Yatsugatake Mountains, at an altitude of 3,750 feet (1,143 meters). They are known for their range of craft beers, including a Weizen and an IPA.
- Andes Beer: This brewery is located in Mendoza, Argentina, at an altitude of 3,600 feet (1,100 meters). They produce a range of lagers and ales, including a Pilsner and a Red Ale.
- Wild Wolf Brewing Company: This Virginia-based brewery is located at an altitude of 1,500 feet (457 meters) in the foothills of the Blue Ridge Mountains. They specialize in a range of craft beers, including a Scottish Ale and a Belgian Tripel.
