“It's English Breakfast, aka 'ordinary' tea if you ask Joe or Jane Public, and this high quality offering is good for three brews, making it a superior quality, cost-effective alternative to even Twinings' own loose EB tea offering sold in supermarkets!
If you're not from the UK though, this tea blend is quite unusual compared to the majority of tea varieties and blends you find around the world, as the British have developed a preference for Assam-based teas over the years which are unusually strong and astringent by international standards.
English Breakfast is also explicitly blended to be best served with milk, which is its most unusual quality. Milk directly combats and breaks down tannin, which can make a tea taste uncomfortably bitter in excessive amounts. Try it with and without milk and see what you prefer personally!”
