Bring 8 cups of filtered water to a boil in a kettle or pot. Once the water boils, set it aside to cool for about 5 minutes so it isn’t too hot for your glass jars.
Put 2/3 cup nettle leaves into one quart-sized mason jar and 4 Wild Berry Zinger tea bags into another quart-sized mason jar.
Pour about a cup of hot (not boiling) water into each of the jars and swirl the jars to soak the tea leaves before filling the rest of the way. Place a lid partially over the jars so the steam can escape.
Steep the Wild Berry Zinger tea bags for 6 minutes. Remove the tea bags and leave the jar on the counter to cool to room temperature before placing in the refrigerator.
Let the nettle tea leaves steep on the kitchen counter anywhere from 8 hours to overnight.
Place a nut milk bag or muslin cloth over the rim of a 2-quart pitcher and strain the nettle tea into the pitcher through the cloth to catch the tiny pieces of tea leaves. You can then gather the bag/cloth and gently squeeze the excess tea from the leaves, but don’t squeeze too hard. Excessive squeezing releases the bitter tannins and makes the tea taste bitter.
Pour the Wild Berry Zinger tea into the 2-quart pitcher with the nettle tea and add the lemon juice. If the tea doesn’t reach the 2-quart line, add enough filtered water to make 2 full quarts. Stir well and refrigerate.
