In a small bowl, add the coffee granules and 1/2 cup milk; sprinkle the gelatin over the milk; let stand until the gelatin is softened, about 5 minutes.
In a large saucepan, combine heavy cream and sugar. Add vanilla extract or vanilla bean. If using a vanilla bean, slice the bean lengthwise and scrape out seeds into cream (add whole bean to cream for additional flavor). Bring cream just to a simmer (do not let it boil), whisking occasionally until sugar has completely dissolved; remove from heat and remove vanilla bean pod. Add the softened gelatin/coffee mixture and whisk to completely dissolve the gelatin.
Strain hot cream mixture into a large glass measuring cup with a pouring spout; pour into ramekins or custard cups. NOTE: Do o't skip the straining step as it removes any bits of un-dissolved gelatin or coffee and insures a nice smooth dessert. Also, do not let the cream mixture cool before straining. If using a vanilla bean, lightly swirl the cream to distribute the seeds evenly. Refrigerate for at least 3 hours or overnight.
To unmold and serve, carefully dip bottom of each ramekin in a baking pan of hot water briefly. Run a thin knife around edge of each ramekin to loosen it from the inside of the bowl. Wipe the outside of the mold dry and place on individual chilled serving plate (topside down). Invert the custard onto the plate and carefully lift off ramekin (shake gently to release). Pour the Chocolate Cream around the panna cotta. Dot drops of the reserved cream onto the Chocolate Sauce and feather it with a toothpick. Also looks great in martini glasses which you don't unmold.
Decorate with chocolate-covered coffee beans and serve.
Place 1/4 of the cream in a bowl and stir in the melted chocolate. Gradually stir in the remaining cream, reserving 1 tablespoon for the garnish.
* It is always best to measure the the amount of gelatin needed as the envelopes of gelatin can vary.
** Half and half, buttermilk, whole milk, and/or sour cream may be substituted for part of the cream.
