Beware newbie alert ]I've just registered with the forum and would like to ask your advice relating to my 2nd/3rd batch of bitter. I recently bought a Youngs Starter kit and brewed up my first batch of bitter for around 20 yrs. To my surprise it was great
so I bought another 2 barrels. My plan is to have one batch conditioning, another maturing and the last one for drinking. This time I tried some Coopers Best Bitter, replacing sugar for 1Kg of Burton Bridge Beer Enhancer. I also switched from the bulb style gas cannisters to an S30. Unfortunately this is where the problem started. When I screwed the S30 to the barrel valve it didn't release the gas, but it did undo the nut holding the valve in place 
. I figured the barrel's seal was now broken so removed the lid, tightened the valve and sterilised it before replacing the lid. 
Should I bin a batch of bitter if the barrel's lid was removed and replaced during the conditioning stage? How do I tell if it needs chucking?Cheers in advance
