What’s happening
Starbucks is launching Starbucks Doubleshot Energy Zero Sugar, a new RTD coffee energy drink line arriving March 23, 2026.
The key details
Starbucks is pitching the new version as:
Zero sugar
Under 100 calories per can
Two flavors: French Vanilla and Dark Chocolate
15 fl oz can format
Why this matters
Zero sugar energy is the default expectation now — and Starbucks clearly wants a stronger foothold in the “coffee + energy” lane without the calorie baggage. This is an attempt to stay relevant as consumers keep shifting toward lighter, cleaner everyday drivers.
What to watch next
How it prices relative to mainstream energy and coffee RTDs
Whether it replaces older Doubleshot SKUs in stores
If Starbucks expands the Zero Sugar line into more flavors fast
