Just on a hunch I thought somebody has tried to use bourbon in jams and I was pleased to find the above recipe...sounds delicious. I love peaches too!
I eat peanut butter and jam on toast almost every morning. Jams also contain high amounts of the fruits antioxidants and polyphenols etc....usually they retain about 60-80% of what the juice contains. So eat up!
"The results indicated that more than 73% total phenolics and more than 65% antioxidant capacity were retained after processing fruits into jams. Optimization of food processing would help to conserve the bioactive phenolic compounds in fruits."
