Pyramid stacking is a semi-permanent structure of barrels that are stacked upon each other with wood wedges to secure their location. Barrels are first stacked empty, and once filled they do not move. The head is often drilled with a 15/16th drill bit near the bottom of the barrel when lying horizontally, and plugged with a standard champagne cork. To empty the barrel, the champagne cork is removed and a barrel tap is inserted into the hole to rack the beer. This method requires less space horizontally than using barrel racks and avoids the cost of barrel racks, however, if a barrel on a bottom row needs to be removed then all of the barrels above it also need to be emptied and moved. Mobility of barrels is therefore sacrificed for space and cheaper cost. Another benefit of pyramid stacking is that a [https://www.facebook.com/photo.php?fbid=10101163850672808 forklift] is not required.
