Quick Answer

Dissolve 1 to 2 teaspoons of Folgers Classic Roast Instant Coffee Crystals in 2 tablespoons of hot water first, then add 1 cup of cold water and ice. Dissolving before chilling prevents gritty crystals and keeps the flavor smooth. For a stronger glass, use 2 teaspoons; for a milder one, use 1 teaspoon.

Why Hot-Water Dissolving Beats Cold Brewing for Instant Crystals

Instant coffee crystals are designed to dissolve quickly in hot liquid. When you drop them straight into cold water, they clump and settle at the bottom, leaving a weak, gritty first sip and a sludgy last one. A small amount of hot water—just enough to cover the crystals—fully dissolves them in seconds. After that, cold water and ice bring the temperature down without sacrificing flavor. This is the single biggest difference between a smooth glass and a disappointing one.

The Cold-Water Ratio That Works Every Time

Use 1 teaspoon of crystals per 6 to 8 ounces of total liquid for a mild cup, or 2 teaspoons for a stronger, coffee-shop-style glass. Start with 2 tablespoons of hot water to dissolve, then add 1 cup of cold water. If you like your iced coffee very strong, dissolve 2 teaspoons in the same 2 tablespoons of hot water, then add only ¾ cup of cold water. The total liquid matters more than the ice, because ice dilutes as it melts. For the most consistent results, brew the coffee concentrate ahead and chill it, then pour over fresh ice.

Choosing the Right Folgers Jar for Your Iced Coffee Habit

Folgers instant coffee comes in several jar sizes, and the one you pick depends on how often you make iced coffee. The 8 oz. jar is a good starting point for occasional glasses, while the 12 oz. jar suits daily drinkers who want fewer reorders. If you want a backup for the office, a travel bag, or a vacation rental, the 3 oz. flip-top jars are portable and resealable. All three use the same Classic Roast crystals, so the flavor is consistent no matter which size you choose.

Flavor Add-Ins That Do Not Water Down Your Glass

Adding syrup, milk, or cream is fine, but each one changes the balance. If you use a liquid sweetener, reduce the cold water by 1 tablespoon so the drink does not become thin. For a creamy iced coffee, replace 2 tablespoons of the cold water with milk or cream. Avoid adding ice before the coffee is fully dissolved; ice slows dissolving and can leave crystals intact. If you want a flavored iced coffee, stir in a small amount of vanilla or caramel syrup after the crystals have dissolved, not before.

Step-by-Step: Iced Coffee With Folgers Crystals

  1. Boil a small amount of water: Heat 2 tablespoons of water until hot but not boiling vigorously. Pour it into your glass. Checkpoint: The water should be hot enough to dissolve the crystals instantly when stirred.
  2. Add Folgers Instant Crystals: Stir in 1 to 2 teaspoons of Folgers Classic Roast Instant Coffee Crystals until fully dissolved. There should be no granules left at the bottom. Common mistake: Adding crystals to cold water first, which causes clumping and a weak cup.
  3. Pour in cold water: Add 1 cup of cold water and stir briefly. If you want a stronger drink, use ¾ cup instead. Checkpoint: Taste before adding ice. Adjust strength now, because ice will dilute it further.
  4. Add ice and stir: Fill the glass with ice cubes and stir for a few seconds to chill the drink evenly. Common mistake: Using crushed ice, which melts faster and waters down the coffee. Use large cubes when possible.
  5. Finish with milk or sweetener if desired: Stir in milk, cream, or syrup after the coffee is chilled. Start with 1 tablespoon of milk and add more to taste. Checkpoint: If the drink tastes weak after adding milk, next time use 2 teaspoons of crystals instead of 1.
