I want to start keg spunding so I want to make sure I have it right and I have some questions.
Im pretty sure I have it down in determining WHEN to transfer to keg so FOR THE DISCUSSION, I'm going to start with assuming transfer to the keg took place with ~4 gravity points left in fermentation.
When transferring is completed, the keg will have no pressure in it. Since the last part of fermentation will generate CO2, do you leave the keg unpressurized and let the natural CO2 pressurize the keg or do you hit it with a little CO2 to seal it and THEN let CO2 build up in the keg?
As the fermentation continues in the keg, pressure will build up. Im assuming one needs a spunding valve, right? How do you figure out where to set the spunding valve? Im assuming there's a calculator somewhere... If you know you have .83 vols of CO2 remaining in solution from fermentation and you want a total of 2.7 vols of CO2, do you use the carbonation calculators to figure out what PSI is needed to achieve the remaining vols of CO2?
Once fermentation is complete, I'm assuming you'll see the spunding valve show a drop in pressure. Once you see the drop in pressure, do you hook it up to CO2,set it to serving pressure, chill and you're done? I feel like I'm missing something here...
When spunding in the keg, I believe this is a scenario where you need to modify your dip tube, correct? How much do people typically remove? 1 inch? 2 inch?
Thanks for the help in advance!
