<Snip> If you are vacuum sealing soon after roasting, how can you tell if it is = gassing out or not? If the lid on the jar is not sealing properly the = gases will escape or leak out, and when you open it, you hear nothing. = If it is sealing correctly after vacuum sealing. when you open it you = will hear the air rushing in, but this does not indicate outgassing, = because by vacuum sealing you have removed most of the O2, so when you = open it, you will hear the swish of O2 rushing in to the vacuumed space. I roasted some Aged Sumatra a couple of weeks ago, and put into 1/2 pint = jars, tighten the lid,( I do not vacuum seal until 24 hours rest), and = the next day when I popped the lid, it indeed outgassed. Of course the = swish heard is actually the air rushing in to replace the displaced CO2, = and O2 gasses escaping.

I roasted about 1/2lb of Aged Sumatra on 2/14. The bean sat out until I was done roasting (about 1/2 hour give or take) and then vac sealed. Roasted some Sumatra Iskandar Triple-Pick and handled the same way. The Iskandar gassed out but the Aged never did. The Sumatra Iskandar smelled wonderful and the Aged smelled kinda funky. Need to get around to tasting it but have any ideas why the Aged did not gas out? Thanks t homeroast mailing listhttp://lists.sweetmarias.com/mailman/listinfo/homeroast
<Snip> sealed <Snip> Sorry Tonya, I must have misread your post, I apologize, I did not mean = to offend. Indeed if the bag is still hard, the beans did not out gas. I = know the Aged Sumatra I roasted 2 weeks ago, roasted to a roaring 2nd = crack, and did out gas. Is it possible that the beans did not get = roasted far enough. Aged beans, like decaf are darker to begin with, and = are hard to judge the roast degree by color. Ron Kyle Anderson SC rnkyle mailing listhttp://lists.sweetmarias.com/mailman/listinfo/homeroast
I vac seal in bags at the moment so it did seal. The beans wear sealed about 30-45 minutes after roasting. t
Tonya, How long did they stay in the vac bag? Some of my beans "pillow" very slowly. And I've only done aged Sumatran a couple of times - but I'm pretty sure they pillowed.
Since 2/14 until today. t
Well if they haven't pillowed by now they aren't going to. Is the vacuum secure - no holes. The pack is still hard?
Yes the pack was still hard this am when I opened it. The smell was not a roasted coffee smell but old green coffee like it had not been roasted!
<Snip> I remember a while back that Rick Farris vac sealed a lightly roasted batch and it never seemed to gas out, which suprised some of us. I have since noticed the same thing myself. Could the aged Sumatran maybe just looked more roasted than it actually was? Charlie ===== Do you Yahoo!? Yahoo!

oh you did not offend, I am used to no one listening to me ;p lol I have roasted the Aged before and they gassed just fine, smelled fine, builded find etc etc. Still have not had just them as a cup, will in the morning. Just seemed stranged that happened this time. I do roast to the 2 crack so I dont know what the heck is going on. oh well.... t
Several things could have happened to your beans, old age, dampness, and under roasted - or all of the above. Just for drill I roasted some this evening and vac bagged it immediately. I'll let you know in the morning - but I know its going to pillow because it smells great. Ran it into second crack because its going to be espresso.
I did do some roasting again this weekend. Same m.o., and everything was gassing out except the Aged Sumatra on Monday am. But I looked at the pouches again yesterday and low and behold the Aged S. was just starting to gas out. Took it 3 days to start but finally did. Last time it was in there a week without gassing out any that I could tell. Last time they did smell funky but when exposed to air, started to smell like roasted coffee after a while. Tasted ok and blended with the triple pick ok. So I have no idea what is going on. These are beans from the same batch as the others. Just thought I would give a update to the strange happenings going on around here. t
