Supermarket beans are typically roasted in large scale factories and allowed to be stored to degas before the coffee beans are packaged - this reduces the variability of the coffee beans packaging dynamics and reduces shipping costs and complexities.
The coffee beans are then shipped from the factory to a holding facility or sorting facility, typically owned or managed by one of the large supermarket chains like Woolworths, Coles or Aldi. When a store requests stock of coffee beans, they are removed from pallet racks, added to the stores other items, shrink wrapped and loaded onto a delivery truck - it may come from an interstate storage facility.
The coffee is then unloaded at the store and held in the store room before it is loaded onto the supermarket display shelves. This journey can be months, and that's before you've even loaded the coffee into your trolley. The biggest problem with this process is coffee is at peak flavour from a few days after its been roasted and for around 4 weeks after - it then starts to change in flavour, complexity and the crema is reduced. You'll then struggle to make a great coffee even with patience and delicate care of the extraction process.
In contrast, your Bay Beans coffee beans are roasted fresh to order and packaged a few hours later that same day - to then be lodged with Australia Post that same afternoon. Its not uncommon to receive your coffee the very next day - it really doesn't get any fresher than that!
The crema, flavour and intensity of your coffee will be nothing short of amazing, every single time. If you've not experienced fresh roasted coffee before, you're in for a treat! My personal favorite is Bay Beans Super Crema - it will knock your socks off!
