Craft an elegant, minimalist product photo of a single sachet of water. The image should be in high-quality black and white, capturing the sachet off-center as it is being poured into a glass. An overhead shot looks down at this scene, emphasizing the dynamic angle and focusing on the texture of ripples in the water, both within the sachet and as it splashes mid-air, creating a frozen splash effect around the glass. The lighting should be soft and diffused, highlighting the texture contrast between the clean, white background and the reflective glossy surface on which the glass rests, adding a subtle reflection of the sachet. Integrate a contrasting textured background to enhance the composition further, adhering to the rule of thirds for a balanced visual appeal. Ensure the brand's logo on the sachet is subtly visible, blending seamlessly within the monochrome aesthetic and minimalist composition.
