Making the Classic Vanilla Bean Cheesecake with Graham Crust can be a fulfilling culinary adventure if you follow these steps:

1. Preheat the Oven: Preheat your oven to 325°F (160°C).
2. Prepare the Crust: In a mixing bowl, combine graham cracker crumbs, melted butter, and ¼ cup sugar. Stir until the mixture is evenly moistened. Press it into the bottom of a 9-inch springform pan to form an even layer.
3. Make the Filling: In a large bowl, beat the softened cream cheese with 1 cup sugar until smooth and creamy. Mix in the vanilla bean paste or extract until fully blended.
4. Add Eggs: Add the eggs one at a time, mixing well after each addition to ensure a silky mixture. Don’t overbeat to avoid incorporating too much air.
5. Incorporate Sour Cream: Gently fold in the sour cream and optional flour until just combined. This addition enhances the creaminess.
6. Bake Cheesecake: Pour the cheesecake filling over the prepared crust. Bake in the preheated oven for 60 minutes, or until the edges are set but the center is slightly jiggly.
7. Cool and Chill: Turn off the oven and leave the cheesecake inside for an additional hour, ensuring gradual cooling. Afterward, remove it from the oven and let it cool to room temperature. Then, refrigerate for at least 4 hours, preferably overnight.

Following these steps will guide you in creating an incredible cheesecake that is sure to impress.
