Foiled again! Things I learned: There are two types of cornelius kegs. Ones with a pin lock configuration and ones with a ball lock. My keg has a ball lock. Guess which type arrived in the mail last night? Onward to Homebrewusa over my lunch break to purchase the correct type and perhaps use my existing locks as a form of discount. We will have ale this Independence day! The liberation of my beer from its glassy cell.
