“I don’t know how much canning you have done so I’m going to describe my entire process. That will also give me a reference.
I got most of my info from this leaflet on canning peaches:

My “extra light” syrup was a little heavier than theirs, 6 c water to 1 c sugar. The first time I did this, I used the amount of FruitFresh it says on the package. (The second time, I didn’t, because I had already learned that they are not going to sit around for months and months, they’re going to get eaten.) The juice of one lemon per batch would also work. I had about 5 pounds of peaches, but some had spoiled spots which I carefully cut out. I ended up getting 3 quarts of halves plus one pint of chopped up bits.
I threw a whole cinnamon stick in the syrup and brought it to a boil (checking with a food thermometer) for about a minute, then turned it to lowest heat. As I peeled the peaches, I dropped them in.
I peeled the peaches by blanching in boiling water for about 45 seconds, then dipping in ice water. I scrunched the skin off and halved them and dropped them in the syrup. Occasionally during this process, I pushed the top peaches under so they all got good coverage about the same amount of cooking.
When all the peach halves were in the syrup, I brought them to a boil for a minute, then turned off the heat. In each quart jar, I placed one cinnamon stick, one whole allspice, and three cloves. (I used half a stick of cinnamon and two cloves in the pint jar.)
I used rubber gloves to protect myself against the heat. I cleaned them beforehand by putting them on and then washing my hands thoroughly with soap and hot water. Like ya do.
I used a canning funnel and dropped the peaches in one piece at a time, cut side down. When the jars were full, I filled them with the syrup to within 1/4 inch of the rim.
Then I wiped the top edges and screw threads of the jars with a wet paper towel, put lids on and put them in a bath of hot water. When the water came to a full boil, I set a timer for 25 minutes and processed the jars.
At this point, there was a lot of syrup left. I put it in a jar, covered it and let it cool on the counter. Then I put it in the fridge. I did not process it for canning, because, fridge. When we put it in our unsweet tea, about one part in 6, the peach flavor was rich and complex.
That’s the end of my process. Here’s some speculation:
You could take 4 cups of water and 2/3 cup of granulated sugar, a cinnamon stick and a clove or two, and a chopped or mashed peach, boil it for 3-5 minutes, then strain, and you would have a very similar product without the hours of work!”
