I came across a clever idea from Greg Terpay in Zymurgy's homebrew gadgets piece called a "Serving String". As a method to control pressure drop through a dispensing line, Greg inserts a length of weed trimmer string into a 3/16" ID dispensing line. The string reduces flow area and hydraulic diameter both of which increases pressure drop WITHOUT tinkering with tube length. The length and number of strings can provide a wide range of tuning.
I have a few highly carbonated brews (serving with 15-18 psi keg through 10 feet 3/16" at 40F) that will not dispense without excessive foam. Recently installed a fan to balance temperature in the keezer but saw only a slight improvement. So, this clever approach is on my radar.
Can anyone shed light on this idea or similar approaches to increasing line pressure drop without lengthening hose?
Cheers!
