Description
What Is the Fibre Boost Sour Grape Protein Bar?
The Sour Grape Protein Bar takes a lolly-inspired sour fruit flavour and builds it into a cold pressed protein bar. Rather than being baked, the ingredients are compressed, which is what gives the bar its soft, chewy texture instead of a dry or crumbly bite. It is not dairy free or vegan — it's made with whey protein isolate and milk protein isolate, and the official pack is labelled as containing milk. Gluten is listed as "not detected" on the nutrition panel.
For more on how cold pressing works and how it compares to baked bars, our complete Fibre Boost bars guide covers it in full.

Nutrition at a Glance
Each Sour Grape bar delivers a genuine dose of protein and gut-loving fibre for under 150 calories. That is a notably different nutrition profile to fruit flavoured lollies and bars that rely on sugar for their tang.
Who This Bar Suits
This is a good option if you want something lighter and fruitier than the chocolate flavours in the range, without giving up the protein and fibre content. Gym goers and active people often reach for it before or after training, and people following a lower carb or keto style of eating tend to like that it is not loaded with sugar. As a protein bar that's tested gluten-not-detected, it suits a wide range of dietary needs — though it does contain milk, so it isn't suitable if you're avoiding dairy or eating vegan.
If you're vegan or avoiding dairy, this isn't the bar for you — it's made with whey and milk protein isolate. Browse our vegan and plant-based protein bars collection for dairy-free options instead.
How to Enjoy It
The Sour Grape Protein Bar works well as a mid-morning or mid-afternoon snack, a post-workout bite, or something to keep on hand when you want a fruitier hit than chocolate. It does not need refrigeration, so it travels well for work, the gym or a day out.
