i know the source you are talking about, what you could do if you wanted is this
take the caber they give you, which should be 0.5mg/mL, get another bottle and add 30mL of everclear(which is 95% ethyl alcohol, or you can convert it to 100%, i'll provide a thread to do this)
this will give you a solution of 60mL with 15mg of caber, or 0.25mg/mL, ethyl alcohol and water are infinitely soluable in each other, and the caber will bond with the ethyl alcohol, which in turn bonds via polar bonds to the water
now you have a completely soluble solution, at least in theory
everclear to ethanol
