Depends on how you store it. U need to treat it like wine. So in a dark cool place away from sun exposure. But open that bad boy up, smell it, does it smell sour or bad, or fine? Pour some in a glass and is there a lot of sediment floating around or is it good? Then sip it. If it tastes good enjoy that and toast !
As with any bottle of wine if it tastes good, it's good to drink. You won't know until you open it and try it. Hope it's good for you.
I'm sure it will be excellent as long as stored properly. Enjoy! Love their Port!!
