10 pts again I promise! I don't know if this wine is still drinkable? it is very old!?

It says some kind of port 1/5 rye 1/5 port 1/2 I think it says 1/2 belle rasberry syrup? Is this even booze lol?! Its called Jul-Glog. Then on the the bottle it says "made according to an oldtime swedish recipe from syrup, water, true and artificial flavors, fruit juices and spicea. My grandfather and great grandfather was from sweden so I'm guessing its really fkn old. But my grandfather passed away and we thought it would be a good celebration of him. It was completely sealed and was never opened. Btw it is also pretty thick. Thank you for any answers!
