Add the peaches to a quart sized (32 ounce) mason jar or large glass jar. The peaches should fill to the top. Add more or less as needed. Add in the lemon juice, no need to stir.
Pour in Everclear until it reaches the top of the jar. For me it was about 2 cups, but pour more or less to get to the top of the jar. Seal with an air tight lid and turn up and down a couple times to make sure the peaches are fully submerged and all parts touching the Everclear.
Place in the fridge for 48 hours, turning/very slowly shaking twice a day.
After 48 hours, Strain the liquid from the peaches using a fine mesh strainer. Pour the infused Everclear back into the large mason jar.
Add the large tea bag or two small tea bags to the boiling water and dunk in and out, allowing the tea to infuse the boiling water. Once the tea seems to have infused the water, pour the cup boiling water (plus the tea bag) into the infused Everclear mixture and stir to combine. Seal and allow the tea bag to sit within the Everclear for 10 minutes.
Meanwhile, heat the 3/4 cup sugar and 3/4 cup water over medium high heat on the stove. This will make a simple syrup. Stir to combine until the mixture boils, then reduce to a simmer for the remaining time until the tea bag has fully infused.
After 10 minutes, remove the tea bag and pour in the simply syrup to the Everclear mixture. Stir to combine.
Store the vodka in an airtight container in the fridge until ready to use. It's best to let it fully chill before serving. Add to your favorite cocktails, like the Spiked Peach Arnold Palmer!
