Will adding sugar to a must add wild yeast?

Hi everyone, I'm brand new to the site and brand new to winemaking. I started a simple batch last night using store bought apple juice and grape juice. I read several forums stating that you need to add sugar to boost the alcohol content in your wine, which after taking hydrometer readings I can now see why. My apple juice was only 6% potential abv and the grape juice was an 8.5. After adding some sugar to the apple I got it up to a 9%. So I was curious, will adding sugar to the juice introduce wild yeast? I spent time sanitizing the stoppers and airlocks and everything that might come into contact with the wine but it all seems to be a waste if I'm just going to be adding sugar which has yeast on it.

Cane sugar is pure sucrose and is extremely unlikely to have yeast in it. Plus, at this point, there is so much yeast in your fermentor that a wild yeast couldn't establish itself.

I actually meant adding sugar before adding my yeast packet. I added the sugar, shook up the container then added my yeast. I added some light brown sugar and some granulated white sugar. Are these both still unlikely to contain wild yeast? Thanks for the quick reply by the way.

I add mine by making a simple syrup, boiled distilled water and sugar, then cooled. I always keep it covered, and use as little water as possible.

I was thinking of doing that but alot of the posts I read, they just added the sugar directly so I figured it would be fine. Oh well I'll just cross my fingers. Thanks for the info everyone. Off topic my yeast is making this neat pattern identical to the Walmart symbol. All of them are doing it actually ha.

My first batch of wine, I added the sugar directly, and stirred the bejesus out of it. It came out fine. When I add my yeast, I put it in a 1/2 cup of my juice (covered, in a measuring cup) and let it bubble and work for a while, then add it to the rest of the liquid. It seems to incorporate better.

not, likely especially if you used campden tablets priot to fermentation

I just opened the juice (Wegmans FYFGA 100% apple juice) dumped some out, poured some sugar in, shook it then dumped more out for a reading, then yeast and airlock. So no tablets or any other chems.
