I made some pear brandy.The recipe said to take ripe pears and place them in a jar with sugar and some vanilla. Then pour the brandy on top of the pears. Then, let them sit for a few months. And, your suppose to shake them periodically, so that the sugar dissolves. When I went to shake them today I noticed that the pears are floating in the jars. Some of the fruit is sticking up out of the brandy and not covered by the alcohol. Is it alright that that happened? Should I have filled the jars up completely?I left about 1in headspace in the jars.
