Sterilize the pint jars, lids and rings by placing them on a tray in your oven, at 220 degrees F, and keep them hot.
Wash and trim the green beans; green beans should be at least 1/4 inch shorter than the top rim of the jar. If needed, snap green beans in half they will fit in the jars.
In a medium saucepan, combine the vinegar, water and salt. Bring to a boil until salt is dissolved.
Pack green beans tightly in each jar. To each jar, add one clove of garlic, a sprig of fresh dill, and 1 Tbsp pickling spice. Also optional to each jar: 1/2 half jalapeño, 1/8 tsp red pepper flakes, and 1/2 tsp granulated sugar.
Ladle the boiling brine into the jars within 1/4 inch of the top rim. Carefully add the lid and band and tighten.
Place the jars in a hot water bath, covering each jar by at least 1" of water. Process for 10 minutes, adding additional time for greater elevations (see chart, below).
Remove jars and place upright on a towel on your countertop. Allow to cool for up to 24 hours. As the jars cool, they will seal - you will hear a "ping" (the center of the jars should not move when pushed).
Jars can be stored in a cool pantry for up to 12 months. Allow the jars to sit for at least 2 weeks before eating.
