What are the differences between using a nut milk bag and a strainer for making homemade nut milk?

Using a nut milk bag for making homemade nut milk results in a smoother and creamier texture compared to using a strainer. The nut milk bag allows for better filtration of the nut pulp, resulting in a more refined and less gritty final product. Additionally, a nut milk bag is easier to clean and can be reused multiple times, while a strainer may require more effort to clean and may not strain the nut milk as effectively.
