What’s the long version? Did they have an explanation?I heard from Yakima Chief, a respectable response. Short version.... I shouldn't worry about it.
If they smell fine when I open them I'll use them.
Hopefully it is not a mouse that got packaged, that would probably affect the hop aroma...Something got in there and generated gas. If it was a strictly chemical process then I suppose it might not have damaged the hops all that much.
@Op did the pouch swell after being put in the freezer or after you removed it?
I have received hop pouches that were not compact/vacuumed seal tight to the hops before but that was like that out of the mail and dont think they changed after being put in the fridge. Always thought it was a operator error.
I prefer the way YVH packages them.The picture the OP provided shows a balloon.
Something seems to be generating gas in there.
I get your point but that seems to be much more than just temperature difference.but did that happen while frozen or after being removed from the freezer?
Yeah if that gas was generated at freezing temp that is shocking.but did that happen while frozen or after being removed from the freezer?
And don't open it in the house...keep a camera on it to see if there is a alien moment.
Most likely packaged with a little trapped freezing nitrogen from the processing.I have a pound of Cascade from Yakima Chief. It's been in the freezer unopened since I got it. It's also blown up like a fresh yeast smack pack. Anyone ever see something like this?
Unless it’s trapped and escapes later?Nitrogen vaporises rapidly once above it's boiling point.
The package would have been fully inflated at the time it arrived not inflating in the freezer during storage.
Trapped in a pressurised cylinder of nitrogen that then develops a slow leak when exposed to freezer temperature.Trapped where?
Guinness hops?Trapped in a pressurised cylinder of nitrogen
More like pockets of liquid nitrogen trapped inside highly resinous hop pellets. Kind of like a ‘pressurised cylinder of nitrogen’, but more likely.Trapped in a pressurised cylinder of nitrogen that then develops a slow leak when exposed to freezer temperature.
Concealed in the packet of hops.
Seems likely!!
Using liquid nitrogen every work day it boils off in seconds.More like pockets of liquid nitrogen trapped inside highly resinous hop pellets. Kind of like a ‘pressurised cylinder of nitrogen’, but more likely.
I guess it depends on how liquid nitrogen gets used in the process. Whether there’s any present during pellet formation, for instance. Not necessarily comparable with your observations for your procedure. It doesn't all evaporate instantaneously, does it? It wouldn’t be of much use if it did. A small volume poured into a mortar, for example, takes a minute or so to evaporate completely. Is it that impossible to imagine highly resinous hop pellets might contain some entrapped nitrogen due to a glitch in processing? Regardless, I suspect entrapped nitrogen pockets under pressure are more likely than a little N2 cylinder inside the hop bag. I pretty certain of that.Using liquid nitrogen every work day it boils off in seconds.
No way would a hop pellet insulate a drop of it. It's boiling off in the thermos flask when you peer in the top.
What’s the long version? Did they have an explanation?
I still wouldn't open them in the house, just in case a foul odor is emitted.Here's the long version. Also I sent them the lot # yesterday. Haven't heard anything yet.
Bag inflation is generally a sign of warm temperature handling or high elevation transport. Yakima
Chief Hops will continue to improve packaging techniques and packaging materials to contain the
bag inflation within the box dimensions.
