M&L of New Jersey swear their formula hasn't changed since the 1800's.... I used M&L Florida water all through the 1960's and 1970's and I know that the current formula is not what I used to buy....The formula 50 years ago was very high proof, my guess is about 80-85% alcohol , and with more complex fragrance...It was closer to 4711 in scent and potency... Two Girls is still a nice , potent Florida water , and still comes in glass...The bottles of M&L
I just bought are also glass, but the formula is weak in both scent and proof....I have not tried the PERUVIAN Florida water , but intend to do so....
