Just saying "if I had to". Plus, I've been moving towards less hoppy beers lately.

Made a fwh nelson kolsch with .75oz and a 90min boil. Came out great and my lady likes the wine notes. I still get confused when drinking it. Eyes say beer and mouth says wine.



I know what you're saying about Nelson. But you should try it in Saison - it's fantastic. Together with the tart thing you get from most saison yeasts, it takes on a white wine thing with the grape-y Nelson notes. Awesome stuff !

I've been planning an all nelson saison. Dialing in some changes using sterling which is my favorite saison hop.

Glass is a perfect O2 barrier, but most vacuum pumps do not create a perfect vacuum. I suspect that a FoodSaver is not even close to perfect.

I also wonder about O2 ingress through the lid seal, but those are designed to preserve food, so probably are good.

But when preserving food in a hot process, the seal melts and forms to the jar. That is why lids are single use.  I don't think using the jars is a bad idea, but I do think bags are better.

agreed, but is it any better or worse than a bag?

jeff - the lids are on tighter than when I have used the in actual canning.  i don't think you will get O2 in via the lid, that is for sure.

Well, not sure. But bags provide the same quality vacuum with a smaller volume of air. As long as they are oxygen barriers, bags would be better.

One would think that O2 does not get into a beer bottle, but it does. The partial pressure of O2 is the driving potential. The cap material has permeability, so it gets in, as the bottle can have very low O2 levels, and the atmosphere has 21% O2. This is why Sierra Nevada went to the pry off caps, a new low permeability liner required high clamping loads than a twist off could provide.

I like to spend time lounging in the freezer on a hot summer day and drink a cold one after mowing the lawn  :P

My vote is for bags.  I buy them in bulk for very cheap and will get multiple seals out of them assuming I don't have a particular powdery hop that coats the inside of the bag.  I just can't believe you get the same amount of air out of the jar as you do from the bags.  I just see headspace in the jar and I know it's not a perfect vacuum and there must be o2 present.

Here's an experimental for someone. Half and peel an avocado. Vacuum seal one half in a jar, vacuum seal the oher half in a food saver bag. Put both in the fridge. The first one to turn brown looses.

Good idea, but a waste of an avocado. ;)

How about an apple?
