In a medium saucepan, pour in 4 cups of almond milk. Heat over medium heat until it’s warm but not boiling, stirring occasionally.
Add 2 tablespoons of arrowroot starch and 1/2 teaspoon of agar-agar, whisking continuously until dissolved and smooth.
Stir in 2 teaspoons of pure maple syrup or organic honey.
Remove from heat and allow the mixture to cool to room temperature.
Open the vegan probiotic capsule and sprinkle the contents into the cooled almond milk mixture, whisking gently.
Transfer the mixture to a clean glass jar, cover with a towel or cheesecloth, and place it in a warm spot for 12-24 hours.
After fermentation, check the yogurt's consistency and taste, then refrigerate.
Serve your yogurt with fresh fruits, granola, or a drizzle of maple syrup.
