Whole or plug hops are used in a hop back, as the goal of the device is to maximize surface contact between the hot wort and the hops. Typically 1-2 oz of hops are used for a 5 gallon home batch. The hop back is inserted at the hot end, closest to the boiler to maximize the transfer of hop oils. Little actual alpha bitterness is added by a hop back, as the wort is not boiling, but a lot of fragile hop oils and aromas can be added. Since aroma, and not bitterness, are the goal it is best to use low alpha aroma hop varieties in your hop back.
Commercial brewers in brewery often make dual use of the hops from their hop back. After the hops have been used in a hop-back, many of the fragile oils have been taken out but the high alpha bittering hop oils remain. Therefore the commercial brewery brewers can take the hops used in the hop back and boil them to extract bitterness in a subsequent batch. While this is difficult for homebrewers to do unless they brew multiple batches in a day, some homebrewers have been able to reuse hops in this way when creating parti-gyle brews (more than one batch of beer from a single mash).
