Frequently Asked Questions
Are sugar-free syrups safe for keto diets?
Most sugar-free coffee syrups are formulated with non-nutritive sweeteners and contain zero carbs, making them compatible with keto. Check ingredient lists if you’re sensitive to specific sweeteners, and use in moderation to avoid aftertaste.
How do I get syrups to mix into iced coffee without clumping?
Use a pump or measured spoon to add syrup to chilled coffee, then stir vigorously or shake in a sealed bottle. For cold milk or cream, swirling or a brief shake with ice helps; concentrated syrups labeled for high solubility perform best in iced drinks.
How should I store syrups and agave nectar?
Store unopened bottles in a cool, dry place away from direct sunlight. After opening, keep tightly capped—some syrups recommend refrigeration while many agave nectars are stable at room temperature; follow the manufacturer's label for best shelf life.
