Hello! Me and a friend is considering serving bought kegs to spare our homebrews abit more on big parties. We would then buy 30 litre kegs with S or G connection. My questions is, what items would we need to setup and serve from a single keg for starters? I have my own kegs at home 18litres with a different connection. What i think is the following: 1. Keg 2. Connection from Keg (in our case G or S) 3. Co2 bottle. 4. Tube between Co2 and Connection 5. Tap to serve from. 6. Tube between the Keg connection and serving tap Do i need a regulator when the beer is already pressurized and we are just using it to push it out? Have not used commersial connections before, but both Co2 and beer tube can be connected directy into the G/S connection in the keg? Is there something more we would need to buy to be able to serve our beer? Best regards!
