Just wondering if using nitrogen to carb will change the flavor of beer vs using co2 to carb. I went to a local bar last weekend that serves a beer called thumpers that i have had before and loved.I had the same beer this weekend(1 week later) and couldn't put down a pint.It didn't taste like the same brew at all..So i asked the bartender what was wrong with it..he said that they had mixed up lines and had been running nitrogen through it instead of co2....and that now it was fixed and running on the co2...I call bull****.I guess my qustion is simple... Can nitrogen change the flavor of beer fom love to hate??? I thought both gasses were tasteless???
