Review by Mopar Rules
Childhood memories! My grandma cooking plum jam on her old, wood fired oven. What an intense and heavy rum on the nose. The dried plums are so present snd dominant, amazing. Different on the palate with a strong bitterness like a strong espresso. Not for cappuccino drinkers and sedan drivers. Burned caramel, oak, espresso, spicy. An imense density. Not as complex as the recently tasted Diamonds Velier 1996 and 1999 but even heavier and richer, more oily. Endless finish of espresso and oak. The empty glas has s mind blowing smell like the burned plums on top of grandma’s plum cake. Love it.

This is a wonderful rum. I'm delighted to have had the chance to try it - thank you very much, Stefan! The profile is Port Mourant per excellence. I have the Karaya in my glass at the same time - the similarities are amazing. Despite the difference in age, Silver Seal is much more intense, while the differences in the profile are mainly characterized by the caramel.

09.02.2024 Nordlichter treffen. Retasting and I stick to my initial score. Opening this one also bacame a masterpiece of work as the Cork broke. Fortunately Stefan didn't give up and after a trip to a decanter and then back through a sift into the bottle, we tried to sniff the decanter and it was out of this world. We tried ti sniff the decanter the next day and it was like putting your nose into a freshly opened bag of prunes. ------------------ Had a nice evening with good friends and a bunch of Silver Seals, some with very nice age to them. This one is very nicely balanced once rested for a while. Woody with dried fruit and spices. I like the light leather, caramel and marzipan on the oily palate. Here I'd say oldies and goodies 😊
Review by DomM
Very nice and richt bottling indeed. Needs quite some pacience to open up, but after some the you are rewarded with a complex nose sporting dark and woody notes alongside some herbs. On the palate the PM is surprisingly approachable with surprisingly little bitterness, which only comes to play at the very end of the finish. Otherwise a brilliant combination of dark, roasted notes anlingside dried fruits and herbal notes which create a very complex array of aromas. Cheers to Stefan for the sample!

Franconian Tasting Gang First of all, a big thank you to MoparRules in the north. Let the impressions sink in once again. I was expecting it to be woody and bitter. But that's not the case at all. What a positive surprise. Simply a very fine wine that very few people will ever have in their glass. You really have to be grateful for that. It's a challenge to be able to balance this out to some extent with MoparRules.

Vielen Dank Stefan für die Möglichkeit diesen hervorragenden Rum probieren zu dürfen. Spannender Vergleich mit dem Karaya, Port Mourant ist klar zu erkennen. Man merkt ihm die extra Jahre an, aber das kann er ab. Der wird nicht zu holzig sondern einfach reifer und eleganter. Das ganze mit einer ordentlichen Portion Trockenfrüchte.
Review by w00tAN
Der Geruch ist so krass, Früchtebrot ist das erste woran ich denken muss. Die Farbe im Glas, göttlich! Im Mund eine so schöne Mischung aus Frucht und Würze mit jedem Schluck entdeckt man neue Facetten. Alkohol ist perfekt eingebunden. Wer guten schweren Rum mag, wird sich hier verlieben. Danke an Stefan für die Gelegenheit zu probieren, wirklich nicht leicht zu bekommen.
Review by Serge
When you open the sample, you are immediately greeted by the most intense scent of moist prunes. Wonderfully fruity and not at all what you would expect from "younger" PMs. The closest asossation might be a 94 REV. Let it rest for now. After a good hour, great notes of licorice, spices and cola (good cola) with orange oils. In addition, beautiful wood, leather and a wonderfully dark and dense character. A dream. Much less bitter on the palate than expected. Beautifully dry. Black tea, earth, cocoa and plum jam join the elements of the nose. Wonderful. A new aspect with every sip. Many (many) thanks Stefan for this very generous sample donation to the Franconian Tasting Gang. ❤️
Review by Christoph H.
One impression is simply confirmed time and time again. Both this and the other PM 75 version from Silver Seal are among the best old school PM noses I know. Without ifs and buts! The smell is incredibly intense, very, very round and simply has everything you would expect from a 75 PM. I particularly notice the sweet, dark fruitiness and tropical fruitiness. A really catching combination of raisins, prunes, passion fruit and passion fruit. The characteristic old, wet and musty wood is also fully present and is on a par with the fruitiness. It continues with lots of dark notes such as treacle, caramel, cola and Ricola herbs. Unfortunately, both Silver Seals have the same weakness: the palate can't quite deliver what the nose promises. Other 75s can do this somewhat better. Even though the rum is still almost 50%, it really seems extremely thin. Sweetness is only perceptible at a medium level, if at all, and the bitterness really hits the longer it is in the mouth. At the beginning there are still clear dried fruits, but these are then covered by herbal and roasted notes. In my memory, the other version is definitely a little better in the mouth. It should have come out of the barrel a little earlier. Overall, I like younger old school PMs with more ABV a little better. The absolute crowning glory here is clearly the Uitvlugt 75 from Cadenheads with over 70% However, this should not obscure the fact that this is still an excellent rum and a liquid story, which undoubtedly satisfies the old PM craving profile
Review by Schnubbi
Nase: Alle Trockenfrüchte dieser Welt. Gaumen: Eine wunderschöne Harmonie aus Trockenfrüchten, Traubennoten und gebranntem Karamell. Leicht bitter und ganz leicht etwas Minze im Hintergrund, etwas Schwarztee. Ganz großartiger Port Mourant!
Review by Jarek
What a nose! Prunes, lots of spice, cola, Maggi, licorice. I agree with Serge that it reminds me of a good REV. If there was a perfume with these notes, I would buy it. Wood on the palate, of course, but just right. Because of the color and the age, I expected wood without end. Enough power, even if ABV suggested less. Thanks to Stefan for the donation to FRTG. This gives you a place in my hall of fame of rum friends 😁
Review by Buddudharma
Ein Privileg, diesen Rum verkosten zu dürfen. Erstaunlich wenig Bitterkeit und ein wirklich tolles, komplexes Profil. Herzlichen Dank an Stefan und die Nordlichter-Crew!
Review by F.L.O.
Man kommt ja nicht jeden Tag in den Genuss eines so außergewöhnlich alten Rum. Lakritze, leichte Bitterstoffe, Holz und Getrocknete Früchte geben sich die Klinke in die Hand. Schön trocken im Geschmack und die Bitterkeit verfliegt dann auch sehr schnell. Dann kommt ein gar leider nicht sooo langer Abgang mit ordentlich Lakritze. Schönes Teil. Danke Stefan ! Heute nochmal probiert, immer noch geil. Doch aufgrund des nicht so langen Abgangs leicht korrigiert
