An improved mixing bottle comprised of at least two chambers, a top chamber and a bottom chamber. Said chambers may be separated from one another, on the outside, by a freshness seal and, on the inside, by a permeable membrane. The top chamber interior will contain a wide mouth funnel with a wide end and a narrow end. While the freshness seal is still in tact, the narrower end of the funnel may point towards the bottom chamber and be situated somewhere just above the permeable membrane.
