Abstract: Appropriate types of wooden pieces, such as oak, rosewood, redwood, cedar, birch, or beech sticks, rods, or balls, are coupled with the cap or cork of a bottle. The wooden pieces are configured to be removably extended into a beverage container for on-shelf or after-consumer-sale enhancement of beverage. This way, while the beverage bottle, for example, wine or liquor, is on the store shelf or is in possession of the consumer after sale, can continue to age or be enhanced in other ways. Cost savings may be realized by omitting the tanks and/or barrels used for holding and/or aging the wine. The wooden pieces may be removed from the bottle at the time the beverage is served and put back in the bottle when the bottle is capped/corked again.
