Over the past few days, I have noticed a funky taste to a few of my beers. One will taste just perfect then the next one will taste kinda smokey. That is about the only way I can really describe the flavor.
For example, I just tried an IPA. 2 nights ago it was perfect, great bitterness, carbonation, the hole shebang. Then tonight I had one and it had the funny smokey flavor to it with little to no bitterness.
Is this oxidation? I guess it is metallic flavor but not really. This was the first batch that I used the bottling wand with, could that be the problem?
