Stove top espresso makers for outdoors and travel. Great little portable espresso makers to take anywhere! The GSI one cup Expresso Maker brews a double shot of espreso in about 90 seconds on low heat. It fits on the Snowpeak Giga stove. You can carry your coffee beans of choice to hand-grind for freshness inside the Java Grind coffee grinder. A wonderful portable luxury for the outdoors enthusiast.
Choose between Stainless Steel and aluminum. Stainless Steel resists corrosion from salt-water. That is why as a sea kayaker it's my personal choice.
Since the acidity of coffee is at most PH 4.3, (PH 7 is neutral) and it takes acidity less than 4 to corrode aluminum, I wouldn't worry too much about the coffee itself causing corrosion. But it's best with aluminum to rinse in fresh water and to dry after use if you want to avoid pitting corrosion.
