Giving life back to an old stale coffee adding lemon using my aeropress

Giving life back to an old stale coffee adding lemon using my aeropress, for this video I used two big slice of lemons, 18g of coffee, 240ml of water for 3 minutes brewing and 30 seconds press, a longer press of a minute would do a better job to extract the lemon juice, with 30 seconds press the result was still good tough. Enjoy!
