Hey all. I have been roasting for about a month now with a stock (not for long) Poppery 1. One of my favorite beans so far is SM's Brazil Fazenda do Serrado PN Yellow Bourbon roasted to what I can tell is about FC. I've been making it in the Chemex. I roasted some last Sunday (8 days ago) along with some other beans from SM. I woke up this morning ground it, poured in some water into the chemex and....no bloom at all. Not a single bubble. The coffee was not good. On the bag it says to wait 48-72 hours before drinking. Could this coffee really have that small of a window to enjoy or could I be doing something wrong. I store in an airtight mason jar in my cabinet. I let the beans de-gas with a loose lid overnight after roasting. Any ideas? I'm going to try a different coffee that was roasted last sunday tomorrow am and see if it is any fresher.

Any thoughts?

That's a very interesting problem you have. I have never heard or experienced such a thing. The 'bloom' is from CO2 generated during the roast. A really dark roast will break down the cell structure of the bean and cause the CO2 to escape more quickly. ( though 8 days is really fast to loose all CO2)  ... is this roast dark or oily?

The only other thing I can think of is a roast so light or underdeveloped that the CO2 was not produced enough during the roast. ( not very likely if it went through first crack)

So the taste was off too; what was the taste like? Any other clues about what the beans look like or what happened during the roast?

I appreciate the reply Frost. I thought it was odd as well. I drank some Colombian this morning that was roasted on the same day and it was good. No the roast wasn't dark and oily but it's not a light roast either. The taste was...I guess flat would describe it. It also didn't have much flavor. I didn't notice anything unusual as the beans were roasting.

 How fast was the roast time and what grinder are you using? Skerton?

I've never really had a bloom issue with my roasted coffee in a drip cone but one issue I had with a popper roaster is under developed inner core of the bean.  The popper roasted the outside of the bean too fast resulting in a grassy flat tasting coffee. I'm not sure it explains the lack of bloom but it could explain the taste.  Also inconsistent grinds can result in under extracted coffee. Depending on your grind type you may want to look into getting a low bearing kit for your Skerton.

I had a skerton but now I'm using a Breville smart. It produces a pretty consistant coarser grind. I don't think the grinder is it because other beans and previous roasts of this bean have been good. This was just my first time using the beans 1 week + out. It is possible that I'm roasting too fast. I separated the circuits last night and added a thermocouple for bean temp and a router speed controller. I will start expirmenting tonight with it

 I once had a lot of JBM I was roasting with a popper.  6-7min roast to full city gave me bad results.   Just throwin it out there.  You can add a little more coffee to the roast to buy you a bit more time but if you add too much your roast will stall out...

Sounds like the greens are too old.  2012 harvest maybe.
