## Abstract

A beverage brewing device is configured to brew beverages such as coffee and tea. A brewing canister having a filter at a bottom end is held partially within a receiving beaker, and a seal is created between the canister outer surface and the beaker inner surface. Brewing media such as coffee grounds and brewing fluid such as hot water are added to the canister, mixed, and allowed to brew. At a desired time, the receiving beaker is moved relative to the brewing canister so that the brewing canister is partially removed from the receiving beaker. As such, a vacuum is formed between the bottom end of the brewing canister and the receiving beaker. The filter stops brewing media from flowing into the receiving beaker, but the vacuum draws the brewed beverage through the brewing media and filter and into the receiving beaker.

## Claims

### Claim 1

A method of preparing a brewed fluid, comprising:
positioning a first container at least partially within a second container so that an opening through the first container opens into a receiving space of the second container, a filter spanning the opening and configured to inhibit a brewing media from passing from the first container to the second container through the opening, a seal established between the first container and the second container;
placing the brewing media and a fluid into the first container; and
moving the first container relative to the second container without breaking the seal so that a vacuum is created within the receiving space;
wherein the vacuum draws fluid from the first container through the filter and opening and into the second container.

### Claim 2 (depends on 1)

The method of claim 1 additionally comprising moving the first container relative to the second container sufficiently to break the seal.

### Claim 3 (depends on 1)

The method of claim 1, comprising mounting the first container onto a first holder and mounting the second container onto a second holder and moving the first holder longitudinally relative to the second holder.

### Claim 4 (depends on 3)

The method of claim 3, comprising moving the first container upwardly relative to the second container from a first position to a second position.

### Claim 5 (depends on 4)

The method of claim 4, comprising stopping moving the first holder relative to the second holder upon reaching a detent, and when the detent is reached the first container and second container are at the second position.

### Claim 6 (depends on 5)

The method of claim 5, comprising pausing relative movement of the first container and second container when they are at the second position.

### Claim 7 (depends on 5)

The method of claim 5, comprising deactivating the detent, and moving the first holder upwardly relative to the second holder until the seal between the first container and the second container is broken.

### Claim 8 (depends on 7)

The method of claim 7, additionally comprising removing the first container from the second container after the seal is broken.

### Claim 9 (depends on 4)

The method of claim 4, comprising placing the brewing media and the fluid into the first container when the first container and the second container are in the first position, and additionally comprising allowing the brewing media and fluid to steep while the containers are in the first position so that the fluid is brewed into a brewed fluid.

### Claim 10 (depends on 9)

The method of claim 9, wherein the fluid is brewed into the brewed fluid, and the brewed fluid is drawn through the filter by the vacuum.
