15 Price Categories Easy to use bar control system for spirits and wine. Inventory control is accomplished by using coded pourers, these are inserted then sealed to each bottle by a tamper-proof security seal. Pourers are available up to 15 categories (for SPIRIT 4000). The metal rings on the pourer use a binary counting system, 1 for the top ring, 2 for the second ring, 4 for the third ring, and 8 for the bottom ring (only on 15 category pourers). Using this method a price category can be assigned to each pourer, for a total of 15 price categories. The pourers each have 3 programable portions that are selected from the front panel of the unit.
