I have been experimenting making wine from coconut i wonder if the same thing holds true for it that its safe?

i read how wine is made and tried making wine with coconut juice. i know it sounds a bit odd since most people make it from grapes and similar fruit, but i have a lot of coconuts and often the price of copra falls to nothing in the Philippines causing me to seek other uses for the coconuts. i wonder if wine made from coconut can be certain to be safe. i know making wine from coconut tree sap results in good tasting wine but there is a natural yeast in the sap that can turn toxic. using the juice from the coconut should avoid this and requires a substitute yeast. i used baker yeast. is there a major difference that can make it unsafe or is it simply cheaper than wine yeast? the wine smells like good wine but i have never tried it, even though i made the first batch 2 years ago. after two years it has become crystal clear and no sediment left, is orange in color and smells like normal grape wine. is the alcohol content a guarantee of safety from bacteria. since coconut oil kills bad yeasts like candida and such i thought initially it would be fairly safe to try, but had no idea if it would work. Then i successfully made it, but was afraid to drink it. I'm planning to get an alcohol tester to determine how much alcohol is in it, i guess that's a start.
