What am I tasting in SA Octoberfest?

I bought a six pack of Sam Adams Octoberfest today. Cracked the first bottle and I taste this astringency flavor Ive had in a few of my home brews. It is definitely a flavor i do not prefer but still drinkable. Id say its an astringent almost metallic flavor. Ive been trying to pinpoint this for quit some time. At first I thought it was an infection but ruled that out. Next I went to chlorine and water quality- don't think that is the problem. I am now thinking it might be a product of fermentation temperatures or mash ph..??

Possibly but i doubt it, could be a certain hop as well?

Any suggestions? I kind of taste it in Newcastle Brown ale as well. The homebrewed beer Ive tasted it in was Northern brewers white house ale.

After drinking another glass the flavor reminds me of wine both the taste and smell. Possibly its the alcohol that isn't masked well enough or oxidized?? This one is really getting to me!
