Answer:
Yes, you can make instant coffee in cold water. It may take a little longer to dissolve completely, but it will dissolve. Because , it will easily dissolve in any temperature water, provided there’s enough of it (which there will be if you follow the directions).
In fact, many people actually prefer instant coffee when making iced coffee, iced lattes, and other cold beverages. This avoids the hassle of brewing coffee and cooling it down in the refrigerator (takes forever) or with ice cubes (waters it down). It also takes far less time than making cold brew coffee.
Of course, instant coffee doesn’t taste as good as freshly brewed coffee. For that reason, I’d really recommend committing to a regular cold brewed coffee routine. But if you still want to add instant coffee to cold water to make iced coffee, consider Starbucks Via packets.
