yes.  as far as i know, sourness is typical of stale beans.

about 15 days post roast is as long as is generally accepted before the beans go stale.

I have been told roasters normally don't want you pulling shots at less than 3 days from roast date.  Some roasters recommend a week for their "sweet spot".  I wonder if your beans are not stale.

even if they were roasted right before they were shipped, i would think that the transit time would give the beans enough rest time...unless they came the next day or something.

if it were the case that he was shipped super fresh roasted beans, i wonder why there would be strange number markings on the bag and no roast date.   sounds like possibly a large commercial operation, in which case, i'd have my doubts.

guess we'll just have to hear what the OP says.  Maybe the beans are ready to brew now?

I dont when the beans were roasted since the marking on the bag is gibberish to me, not close call of looking like a date or something...

But...lets say they were roasted the day before they were shipped, it took about 3-4 days to get them shipped to my place from the date of ordering...

The main thing I think in this case is that the valve was shut closed not letting the beans breathe...
I also think that they use nitrogen to fill the bags to keep the beans fresher when they arrived to your house...Therefore explaining that weird gas smell...

I have disposed some beans in a vacumm bag, and did not open it yet or notice inflation from the bag...
I also put some beans in a ceramic air tight container and it seems the odor of the beans is getting better, I shook em up and it seemed like the gas bad smell showed up again...but still it smelled better.

I tasted those beans the very first day they arrived, and the next day and both times they were awful, crazy sour and all,
I will be testing them today and I`ll give it a try, and will let you know...

Im hoping the beans are on their way to their sweet spot and that the nitrogen taste and smell will dissipate(if its the nitros fault!?)

If they are fresh I am pretty sure they will puff up a new bag in a day or so as they release gas.  If they don't, I am going to guess they are stale.

i dont know how any of us can figure out when these were roasted.  if they're old, they'll taste stale(likely sour).

nitrogen flushing shouldnt cause the noxious scent you're talking about.  illy and lavazza use nitrogen flushing and i dont remember hearing about any gaseous scents.  also they use nitrogen for potato chips.

i'd just pass it off as stale beans and possibly not use the roaster anymore if they dont tell you when the beans were roasted.

Sounds good Frank828...
They must be stale, I tried again today, and the taste is still pretty bad!
Like you said no roast date...
:(
