Combine sugar & 1 quart of water and boil over medium heat for 25 minutes. This is commonly referred to as simple syrup.

In a separate pan heat 1quart of water then add the coffee.

Wait for syrup and coffee to cool then mix together with vanilla and PGA. If you do not wait for the cool down the alcohol will evaporate.

Instead of instant coffee use strong brewed coffee to taste or diluted espresso to taste.
