Overall similarity
hopIQ take
Fuller's London Porter if you want classic restraint,
Robust Porter if you want modern boldness.
Both sit at nearly identical ABV and IBU, so the difference is really about philosophy—Fuller's leans into a 150-year-old formula of chocolate and subtle smoke, while Reuben's gives you deeper roast character and a slightly thicker mouthfeel. Neither is better; it's whether you're in the mood for tradition or a contemporary take.

Tasting notes
Fuller's London Porter
Fuller's hits you with immediate cocoa and a whisper of woodsmoke—nothing aggressive, just quietly confident. There's this biscuity backbone that makes it feel lighter than 5.4% should allow, and the finish is dry without any lingering bitterness despite the 33 IBUs. It's the kind of porter you can drink three of without feeling like you've been beaten up.
Robust Porter
Reuben's feels noticeably richer from the first sip—darker roast, deeper chocolate, almost like someone turned up the volume on everything Fuller's does subtly. The body is fuller (pun intended), and there's a slight licorice edge that adds complexity. It finishes cleaner than expected for something this substantial, which keeps you coming back.
