I brewed an ESB and a porter in time Christmas 2012. I kegged both batches and both beers turned out great. Over the next 2 months I drank 1/2 of each. Then due to some medication I was taking for several months I was advised not to drink alcohol. Unfortunately my 5lb CO2 ran out of CO2 and I did not realize it until I tapped a beer last weekend, and found that both beers were flat. No carbonation.
If I recarbonate my beer will it affect the quality of my beer? Or should I just dump the beer and put it down to experience?
