We Tested Coffee From Costa, Starbucks, Tesco & 8 More — Here's What The Label Is Hiding

We tested coffee from 11 of the biggest names in the UK, from Costa and Starbucks to Tesco, Greggs and Aldi, and what we found on the labels will change how you shop. Most brands are hiding behind vague wording, recycled badges and premium fonts while sourcing from the same industrial pipeline. We ran every product through three simple questions and almost nobody passed. Here is exactly who failed, who cheated, and the one chain that actually answered everything. #coffee investigation, #UK coffee brands ranked, #is Costa coffee worth it, #Starbucks vs supermarket coffee, #best coffee UK 2026, #Rainforest Alliance badge explained, #supermarket coffee exposed, #UK food investigation
