CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application claims the priority of U.S. Provisional Patent Application Ser. No. 62/261,681 filed Dec. 1, 2015, which application is incorporated in its entirety herein by reference. 
    
    
     BACKGROUND OF THE INVENTION 
     The present invention relates to brewing cartridge racks and in particular to a brewing cartridge rack for attaching under a cabinet having a downward reaching lip. 
     A large variety of brewing cartridges are available offering a wide selection of brewed drinks. Users often desire to locate a brewing cartridge holder close to a coffee maker for easy access to the cartridges. Because counter tops can easily become cluttered with various kitchen items, and the brewing cartridges themselves are not large, a brewing cartridge rack can be positioned under the base of a cabinet. 
     Known under cabinet brewing cartridge holders include a cartridge holder which slides forward. Unfortunately, many cabinets include a downward reaching lip which prevents the cartridge holder from sliding forward to access the cartridges as shown in  FIG. 1 . One solution has been to pivot the holder at the rear as shown in  FIG. 2 , however, the cabinet lip still limits access to the cartridges. 
     BRIEF SUMMARY OF THE INVENTION 
     The present invention addresses the above and other needs by providing an under cabinet brewing cartridge holder including a cartridge rack which both pivots at the rear and slide forward to clear a downward reaching lip along a front edge of the cabinet. The cartridge rack includes opposing lateral pins near the rack rear, which pins slide in horizontal slots in holder side walls. A sloped rear surface limits the downward pivot of the rack, and magnets retain the rack in the stored position. In another embodiment, a second under cabinet brewing cartridge holder includes unequal length arms attach a second rack to a slider engaging the horizontal slots. The second rack pivots down and away from the holder and slides forward and rearward.
