As I expected, this tweet by the VFX developer who wrote it confirms that this isn't a CPU-based physics simulation but instead just a shader. As far as volume preservation, you could probably solve for an exact calculation for general approximation of a bottle shape, and just invert that. I think there are a lot of ways it could be done. This is what it looks like. Now you'd probably just want to do vertex offsets, but if its raymarched it would look a lot cleaner, i just know I had a lot of difficulty cheaply raymarching sine waves before, so vertex offsets would be my choice. Finally add some noise and make sure you only render inside the bottle and presto, you probably have some rough approximation of wine. We've made our version of the Half-Life: Alyx liquid shader.
