“Das ist ein wunderschöner Rum. Ich freue mich sehr, dass ich die Chance hatte den zu probieren - vielen Dank, Stefan! Das Profil ist Port Mourant per Excellence. Ich habe den Karaya parallel im Glas - die Gemeinsamkeiten sind verblüffend. Trotz des Alltersunterschieds, Silber Seal ist deutlich intensiver, im Profil sind die Unterschiede vor allem vom Karamell geprägt.”

“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 😊”

“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!”
