So my second batch taht I just bottle of german hefeweizen did not come out so perfect the carbonation did horrible. There are some bubbles but not alot. My first bottle I tried did very well but 1 out of 3 was carbonated the rest with no head retention or little bubbles. I use muntons carb tablets I put 5 in each 12oz bottle just like it says in the instructions. I do 2 gallon batches all the time. Does anyone have any other advice and ways to do this?
