Overview
What makes CLIF Bloks Sours different from standard Bloks?
CLIF Bloks Sours Energy Chews Box of 18 is a full-season supply of the chew designed to solve flavor fatigue: the real and common problem of sweet overload that builds up on long rides when you have been fueling with gels and chews for hours. The pronounced sour profile cuts through sweetness fatigue, keeps your palate working in your favor, and tends to encourage better hydration behavior on the bike. CLIF developed the Sours line in 2024 in direct response to athlete feedback, specifically for use during long endurance efforts where flavor monotony becomes a performance factor. Available in two flavors: Sour Green Apple (caffeine-free) and Sour Strawberry Lemonade (25mg caffeine per serving via green tea extract).
Each packet contains 6 cubes. Serving size is 3 cubes, delivering approximately 21g of carbohydrates and 107mg of sodium per serving. Non-GMO, plant-based, no high-fructose corn syrup, no artificial flavors. Gluten-free. Always consume with water. The box of 18 is the right format once you have confirmed these are a staple in your long-ride fueling kit.

FAQ
Good questions
Get to know CLIF
There's more to CLIF than this one product. Our CLIF page has the full CLIF lineup we carry and more about the brand.
Visit the CLIF page →Which Sours flavor contains caffeine?
Sour Green Apple is caffeine-free. Sour Strawberry Lemonade contains 25mg of caffeine per serving (3 cubes) via green tea extract.
How do the Sours compare nutritionally to regular Bloks?
Sours deliver approximately 21g of carbohydrates and 107mg of sodium per serving (3 cubes), at approximately 80 to 90 calories per serving. Standard Bloks deliver approximately 24g of carbohydrates and 50mg of sodium per serving at approximately 100 calories. Sours are slightly lower in calories and carbs with higher sodium per serving.
Why would I use Sours instead of standard Bloks?
Sour flavors are designed for athletes who experience sweet overload during long efforts, making it difficult to keep fueling consistently. The sour profile is palate-resetting and encourages drinking more water, which supports better hydration and absorption during extended rides.
How do I use CLIF Bloks Sours?
Half a packet (3 cubes) 15 to 30 minutes before activity. Then 3 to 6 cubes every 20 to 30 minutes during activity. Always consume with water.
Should I try individual packets before buying the box?
Try the individual packet first to confirm you like the sour profile and specific flavors before committing to a box of 18.
