Use freshly brewed espresso.Freshly brewed espresso or strong coffee ensures the richest flavor. If possible, grind the beans just before brewing for the freshest taste.
Shake vigorously.The key to a well-mixed and frothyoatmilk shaken espressois to shake it vigorously. This helps to combine all the ingredients thoroughly and creates a creamy, frothy texture. Use a cocktail shaker or a glass jar with a lid for the best results.
Adjust sweetness to taste.The amount of agave nectar can be adjusted based on your personal preference. Start with a small amount and add more if needed, tasting as you go.
Use chilled ingredients.Cold oat milk, plenty of ice, a chilled shaker, and a chilled glass will keep the drink refreshing, cold, and frothy, despite using freshly brewed hot espresso.
Use espresso ice cubes.If desired, freeze brewed espresso, coffee, or cold brew in an ice cube tray and use the frozen coffee cubes instead of regular ice. This will add extra flavor to the drink as the cubes melt.
