MireHawk · Accepted Answer

Freeze dried coffee granules. Freeze-dried coffee was actually invented by Nestlé in 1901, but it took decades to perfect because the process is surprisingly tricky—you have to freeze the brewed coffee and then use a vacuum to remove the ice without destroying the delicate flavor compounds that give coffee its taste. The result is that instant coffee can sometimes taste better than regular drip coffee because the freeze-drying process preserves more aromatic oils than traditional spray-drying methods used for cheaper instant coffees.
