A wine fermentation device for fermenting wine, and skins, seeds and stems which form a cap. The device includes a tank having cylindrical walls, an axis and a bottom. One or more optional interior baffles may be provided. At least one drain is located at or near the tank bottom. The device includes at least one impeller, and in a preferred embodiment two impellers, each impeller having a plurality of blades to radially and axially move the cap during fermentation and to blend the cap with liquid to permit draining of the cap (or pomace) through the drain.

1. A process for wine cap management for fermenting grape juice and skins, seeds and stems which forms a cap, which process comprises: positioning a tank having cylindrical walls, an axis, and a bottom so that said cap will float parallel and opposed to said bottom; filling said tank with said grape juice and said skins, seeds, and stems so that said cap will float above an impeller; fermenting said grape juice and said cap in said tank to produce wine having cylindrical walls, an axis, and a bottom; moving said wine radially and axially by periodically rotating said impeller having an axial shaft within said cylindrical tank, wherein said axial shaft is perpendicular to said floating cap; moving said cap radially and axially by fluid force generated by movement of said wine wherein said wine movement is generated by said rotating impeller; and assisting axial flow of said wine with at least one baffle extending from said cylindrical walls toward said axis. 2. A process for wine cap management as set forth in claim 1 which includes the additional steps of adding yeast and sugar to said fermenting wine or must to promote fermentation. 3. A process of wine cap management as set forth in claim 1 which includes the additional step of controlling the temperature of said wine in said tank through a temperature jacket. 4. A process of wine cap management as set forth in claim 1 wherein said impeller shaft is driven by a motor. 5. A process of wine cap management as set forth in claim 1 including two said impellers extending horizontally from said axial shaft. 6. A wine pomace removal process for wine and skins, seeds and stems forming a cap fermented in a tank having cylindrical walls, an axis, and a bottom, wherein said cap floats parallel and opposed to said bottom, which process comprises: draining a majority of said wine from said tank through a drain at said bottom so that a minority of said wine and said cap remain; agitating and blending said cap with liquid wine remaining within said tank to create a pomace slurry; and draining off said pomace slurry through a drain at or near said bottom of said tank. 7. A wine pomace removal process as set forth in claim 6 wherein said drain includes a valve. 8. A wine pomace removal process as set forth in claim 6 wherein said agitating and blending step is accomplished through an impeller having a plurality of blades which are rotated by an axial shaft driven by a motor. 9. A wine pomace removal process as set forth in claim 8 including two said impellers, one located near said tank bottom to agitate and blend said cap. 10. A wine pomace removal process as set forth in claim 6 wherein said bottom of said tank is substantially planar and is sloped in angular relationship with respect to said axis of said tank. 11. A process of wine cap management as set forth in claim 1 wherein said bottom is substantially planar and arranged in angular relationship to said axis.
