1. Twist hard: First, you can twist the cap of the pepper bottle hard in order to try to open it. You can use tools such as a clean towel or rubber gloves to improve your grip in order to twist the cap more easily.

2. Hit the cap: If twisting it hard doesn't work, you can try gently tapping it on the edge of the cap with the palm of your hand or a tool like a rubber mallet to loosen it. This method can relieve the pressure between the cap and the bottle, thus making it easier to open the cap.

3, use warm water: you can put the bottle in warm water for a period of time, wait until the bottle becomes warm and then try to twist open the cap. The warm water will soften the glue between the cap and the bottle, thus making it easier to open the cap.
