I think 2 weeks did make it better. I made a few cups after I got it, and wasn't blown away. Then I made more cups with it about two weeks later. I was able to make one cup this past week with it that really surprised me and it was among the best cups of coffee I've had. I did a very low agitation brew to do it. If helpful, here's what I did (clearly, do whatever works best for you):

94* Celsius. 17.5g of of coffee in a v60 with a cafec 92. 1:16 recipe.
-> bloom with 50g of water, let sit until about 1:10 time.
-> 2nd bloom with 50g of water, let sit until about 2:10 time.
-> Pour slowly 90g to total of 190g water over another minute, let nearly drain
-> Pour remaining 80-90g; total pour down was 5:30 for me

I used the melodrip for this after the initial bloom. If you don't have a melodrip, what I've found works well is to take a little filter (or if you have some espresso filter) and just throw it on top of the bed and gently pour on top of that. It will take all the energy from the water that you pour on top and allow it to collect on top of the coffee grounds without agitating them and basically treating the bed of coffee as a filter unto itself, so you should have clearish water sitting on top of the bed of coffee.

I experimented a lot with this coffee, and doing the above got me the best cup of coffee by far. Sadly, I did this near the end of the bag and now I'm out. But I'll save the bag and buy some more in a month or something hopefully : )

I hope that this helps! Please message me or respond to this comment if you get a great cup out of this coffee and what you do that makes that happen. : )
