PinkRose, any fresh roasted coffee needs to age before use, otherwise most is too harsh to consume from the degassing process. This is especially true when used for espresso. After much tinkering I have an aging/vacuum packing/freezing process I go through when buying in 5 lb. increments from our roaster. This allows me to have extremely fresh coffee as needed for 5-6 weeks after roast.
Can't say that aging under certain conditions is truly more beneficial, but if it works for you/customer then so be it. For the coffee that I use for espresso I know it starts to peak at day 5 after the roast (based on using thousands of pounds of that coffee) and letting it sit at room temperature in the foil lined bag for exactly 5 days, then vacuum packing/deep freezing will give me 5 day old coffee every time I thaw/open a new jar. And people think coffee is just coffee, lmao.
