I have always wanted to do a read accurate clone of Monster Energy drink, so I bought Green Goblin FW and Energy Drink TPA. My initial test of Green Goblin at 15% was weak, 20 and 25% were closer, but still not close enough. I have settled on 20% as a base and will experiment with flavors to add to it to get a good clone.
My Red Bull attempt at 15% was good, a little weak and sweet compared to the real Red Bull drink out of the can, so I am going to 20% to try, should be very close. Then I will add a little Sour to try and make it like read Red Bull.
Any ideas of additional flavors to add for Monster or Red Bull would be appreciated.
