Hi argivez and Welcome.
I'm with Kayelle on this one. You can only try and see.
Sort of interested in why you are asking. Are you wanting the alcohol to disappear or still be there.
Because of the speed of 'toasting' I rather think that although a lot of the alcohol will dissipate I doubt that all of it will. Certainly not enough would remain to be a problem, on the other hand believe enough of it would remain for flavour.
Not something I would make a highlight of for kids ...and adults will already be well "into it" to probably not notice!
