Thanks for the input my friend always welcome.Hi there
I hope you dont mind, I had same problems as HasHHassin and I think I know what the problem is
I think that he is using a vacuum bag for clothes and not food. Those bags dont make tight vacuum, they leak big time
I have a problem because this is the only kind of vacuum bag available in my area and it sucks, it doesnt make real vacuum. I tried same like him with these bags and it does not work, there is no vacuum and cob come out of the yoghurt maker too dry
Try another method for vacuum. I tried wrapping it very tightly with nylons and cord and it was better, it was the method shared by Carraxe and results were very similar to paraguayan brick
I hope it helps and have a nice weekend
Pd: if anyone is trying space coffee and have taste problems, please cook it with turkish coffee with cardamom, this is the best for masking taste and making it smoother to your palate. I personally never cared for taste when I have such coffee
Total vacuum is not that important you can make good cob cures without any vacuum at all it just makes mold less likely with no air in the bag.
The main things you need to get right are temp and moisture content.
Looking at the pictures again in close up I think moisture content is probably the problem if the buds are too dry nothing much happens.
