As long as you keep all the fruit submerged in alcohol, it should stay safe. But you have to weight everything down (with a plate, for example) for that.
I've never done it myself, but I remember reading about a concoction called Rumtopf, for which you keep layering fresh fruits with sugar as they come into season, covering them with more rum each time, then leave the whole thing for a few months (the timing is the same as you mention). It's a German and Austrian specialty. |
