Hello, recently I found a Wood Roasted Espresso from Nevada I believe. I ordered American Espresso and it took a week to get to me via Fedex ground. I live in MN very cold. Box beans came in sat outside my door for 8 hours in 0 degrees.
I let beans warm to room temperature before opening and putting in airtight food saver container. Next day I looked at beans and even now there appears to be little drops of oil on the outside of the beans. IS THIS NORMAL?
Also, I like Espresso I used to get in Spain or Italy. Anybody have any espresso suggestions I could order?

Under normal circumstances, the appearance of oil on beans is attributed to the amount of heat they've been roasted in.  The hotter the roast, the more oil will seep out of the oil. This is perfectly normal.

I am not sure if the conditions the beans were in also attributed to the release of oil or not.   I doubt it.   If the oils are actually wet and you mistaken the moisture for oil, then that is a problem.  But if there is just little bits of oil on the beans, it's normal.

Anyway it might help to educate yourself on what to expect when looking at beans.  I suggest you read the following article:  Using Sight to Determine Roast Degree

That was a very helpful link. My beans have spots of oil seeping out after a couple of days of opening bag. The beans are dark too, I think this batch may have been over-roasted. It was from a wood fire roaster. I did get an excellent bag of Vaggio Italian blend which was his specialty. However, since the shipping took 7 days fedex ground and coffee seemed over roasted. Im going to try a new vender, "Muddy-dog".

A few drops of surface oil, while not particularly desirable, should be ok. What you really want to avoid is beans that are slathered in oil. I see scattered surface drops occasionally on beans I get from Klatch. Stick your nose in the bag and take a good whiff. If they smell good, they'll taste good. I suspect that beans with slight surface oils don't last as long, perhaps shorter than 15 days, but haven't really looked for any confirmation of that.

They look like they could be over-roasted. How do they taste?

Sorry getting back late. My mistake the beans were not over roasted. I learned with darker roast the oils tend to come out naturally in a few days and disappear after a bit of time has elapsed.
The taste was really dull and I was wondering if it may have been due to the 7 to 10 days it took UPS ground to get the coffee to me; also, I live in MN subzero temps right now.
It was probably just this batch as I got some Italian Vaggio from this vender that rocked and would order it again.

To get oil on coffee beans indicates a dark roast. It's good that you learnt something with this experience. Thanks for sharing your experience of Italian Vaggio. I will definitely try.
