Prepare the Sun Tea Jar: In a large, clear glass container (at least 2-quart capacity), combine the 8 cups of water, 6 black tea bags, sliced strawberries, and fresh thyme sprigs.

Dissolve the Sweetener: Add the 0.5 cup of granulated sugar to the mixture. Stir gently until the sugar is mostly dissolved. If using alternative sweeteners, add them now.

Sun Brewing: Seal the jar tightly with a lid. Place the jar in direct sunlight on a porch, deck, or windowsill. Allow the tea to brew for approximately 4 to 6 hours, depending on the intensity of the sun and desired strength. Do not let it brew for longer than 6 hours to avoid bitterness.

Strain the Tea: Once brewed, carefully remove the tea bags, discarding them. Pour the tea through a fine-mesh sieve into a clean pitcher to strain out the small pieces of strawberry and thyme leaves.

Chill and Serve: Taste the tea and adjust sweetness if necessary. Cover the pitcher and refrigerate for at least 1 hour until thoroughly chilled. Serve over ice, garnished with fresh strawberry slices and lemon wedges.
