I am definitely disappointed with the results.  I had bought three bags of espresso to avoid the extra shipping expense, but now I have 2 frozen bags that don't hold up to espresso making.  Lesson learned.  Luckily I live near and they will ship for just under $5 a bag.  Still steep but espresso is an expensive hobby.

Tried home-roasting?

I can't get decent coffee where I am either, and shipping pretty much doubles the cost of a pound of coffee, so I turned to home roasting and buying large quantities of green ( half sacks at a time ) to save cash

If you vacuum seal before freezing you'll be OK

Vacuum seal how?  I kept in original sealed valve bag, wrapped in saran wrap, tin foil, and then in ziplock.  Still lost flavor.  Thanks for any help.  Not sure I am ready to roast my own....yet.

 What temp is your freezer set to? A stand alone freezer or your fridge/freezer? How long were they frozen?  I keep my storage freezer set to 0*F & can pull vacuum sealed bags of coffee out after 6-8 weeks or more & get excellent shots.

Freezing has worked out really well for me. I order 5 pounds at a time, then break it down into 1/4 pound packets that I vacuum pack.

I've broken open packs 4 months later and still pulled shots with loads of beautiful crema. If I leave a packet on the counter unopened, it will restart outgassing after it thaws.

You can pick up a Food Saver device from Costco for a decent price (that's the unit you see in the OP's picture with a package)

IMO no, they won't.

I'm a convert to vac-sealing and freezing green (and have a 1 and 2 year experiment ongoing regarding that), but have yet to see or taste any tangible benefits from freezing roasted coffee, even when vacuum sealed.

Buy fresh roasted. Use. Buy more fresh roasted. Or roast at home.

OBJECTIVE: A prospective, double blind, randomized, placebo controlled study to identify and determine perceived difference in vacuum sealed, 30-day frozen, vs fresh coffee

MATERIALS:
Fresh day-4 post roast coffee from well known, professional local roaster
Vacuum sealed, frozen for 30 days, followed by four-day degased coffee, from same local roaster; same blend
Quickmill Anita with Eric’s thermometer and naked portafilter
Versalab M3
ACF Tulip espresso cups
Coffeegeek

METHODS:
The control group will be 14g of fresh coffee each in six small containers with randomly assigned number for identification.

The experimental group will be 14g of fresh coffee each in three small containers and 14g of frozen coffee also in three small containers, with randomly assigned numbers for identification, in random order.

The coffeegeek will grind and pull six shots in the control group, taste, write down either “Frozen” or “Fresh”

The same coffeegeek will then grind and pull six shots from the experimental group, taste, and write down either “Frozen” or “Fresh”

Who is the coffeegeek volunteer?
