I would read this phrase as "basically". Distillation is a process of purifying a liquid, and the essence of a thing is its "intrinsic nature" that "determines its character." Therefore, I would take the phrase to mean "Once the situation has been simplified enough to contain only the most important and defining parts of itself." (definitions from google dictionary)
