My first few home brew ales were bottled and had a good level of carbonation. I then purchased some corny kegs and Co2 with a 60/40 mix. Everything works fine but I much preferred the bottles as they had more carbonation and seemed fizzier which I like. I have tried upping the serving pressure but it seems to just give more foam. How do I get my beer fizzier? Should I go for a higher C02 mix?
