Silver Seal Port Mourant Demerara 1975
Poured neat, this is a slow, contemplative Port Mourant: heaps of prune on the nose, then chocolate, old leather, oak and molasses on the palate. The 37 years show as a deep, full body with just a touch of sweetness and a bitter edge some love and some find a bit much. One taster called the finish one that "snap never ends," with the alcohol almost invisible.
The community says- Deep prune & leather
- Long, evolving finish
- Alcohol well integrated

The look inside the bottle
How does Silver Seal Port Mourant Demerara 1975 taste?
Aggregated from 20 community reviews.
Deep, woody old Port Mourant with prune and bitter edge Members rate it very highly — complex plum, wood and leather with a near-endless finish. A few find it tips slightly bitter from all that age; one wished the taste lingered longer.

Review by Kevin Sorensen 🇩🇰
This is a great sip of a very rare bottle made on the oldest still in the world. Very expensive golden drops but well worth it.
Review by Leo Tomczak
Inspiring rum. Bottled at just the right time before it turns bitter. Tastes like a 94 REV only better. Great woody notes, eternal finish. Comprehensive creaminess and even a slight sweetness despite its great age. Wow!
Review by Johannes Eisner
A full load of plum on the nose, then a little more bitter on the finish than other PM 7x.
