I purchased a Monster today Sunday 27th of May and when i opened the can it got me wondering if it was gonna be fresh...I tasted it and it had an absolutely flat taste and the taste was not at all flattering....I purchase 1-3 monsters a day and never had an issue with the product in 2yrs till today...For the most part great product !!! Thank You for your time on this, and have a great day...Lisa Bell
