I tried my hand at a pear cider last week. I started off with a 1qt starter of wyeast1058 made with pear juice, the yeast came out of a patch of IIPA and went in to the fridge and then I brought it back with the pear juice, the yeast did fine in the starter. I used 3qt of Gerber brand pear juice, plus the starter for a gallon, I also added 3qt of store bought apple juice and around a gallon of pear juice from some fresh pears. I also added 12 oz of honey and about a cup of dextrose. I decided to pasteurize at 180 for 30 min. The only issues I had was a yellow jacket flew in to the cider about half way through the pasteurization, I fished it out and spent the rest of the time fighting off other bees. It went in to the fermenter Monday, I aerated well as I cooled the cider. I took my first taste today and it was odd. It wasn't very cider like, it was very dry and wine-y, the pear comes through well on the finish but its got a slight bitter start and a slightly sulferic twang. I'm wondering if I've done some thing wrong. It fermented aggressively for a day and its still going slightly, I don't have a hydrometer but there is a good alcohol warmth. Does this sound right? Does it need more time or am I making pear vinegar?
