It depends on the drink. Iced teas get LCS which is always a cbs pump. So venti is 6 cbs pumps. A regular cold brew with an added syrup would get normal amount espresso bar pumps. Specialty cold brews like SCCFCB, pumpkin cold brew, etc. get cbs pumps or halved espresso bar pumps. Carmel is commonly cbs pumps at cold bar for the SCCFFB and Frappuccinos and vanilla is usually a cbs pump for the other specialty cold brews.

ETA: any time a different syrup is switched in one with cbs pumps, you don’t half the pumps. So sub classic in a tea is 6 full espresso pumps not 3.
