On every BarrelSmoker that leaves here there is a water pan which is mainly recomended to fill with concentrated fruit juice for the first third of the cook then switch to straight water unless adding fresh product then use juice again, same way. It's not a distinct ready obivious taste, but it's just a subtle twist that plain water doesn't add. I figure if were using fluid why not. It doesn't add that much cost when using frozen concentrates. Not worth using bottled diluted juice products. Also in our 55's were using a 3 gallon pan ,sometimes a 2 gallon one and rarely but sometimes a 2 gallon filled half full with clean play sand and lined with foil. It all depends on the cooker and airflow is very important to the puzzle. Steve.
