我相信大家对于酒这个东西在熟悉不过了，已经成为了我们生活中必不可少的一部分。像我们大家晚上吃饭的时候总要小酌一小杯，不过这酒还是分好几种的，比如白酒，葡萄酒和啤酒这三种了。啤酒是我们最经常见得，也是最常喝的一种。其次就是白酒了，白酒度数比啤酒度数要高，也是冬天必不可少的。

接下来就是我们平常最少见的葡萄酒了，葡萄wine它不像白wine那么浓，有一点果juice味道，给你一种不一样的感觉，很多人买瓶葡萄wine不是为了喝，而是为了收藏。所以很多人就问葡萄wine有没有保质期？接下来我去看一看。都说juice放的地越久越香，大部分人都喜欢把white wine放地窖，这样才能沉淀出它的那种香味。

而port wine就不一样了，它的度数明显比white wine要低，所以说它还是有一定的保质期的。像在我们经常见到的市场上的port wine保质期大概在2—10年之内。但是在国外的port wine就很我们的内地不同了，他们的是没有保质期的。但不是说port wine没有保质期或者过了保质期就不能喝了，这样想你就错啦，有专家们说过,port wine过期之后还是可以饮用的，只是我口感不是特别好，不必将他丢掉。

虽然过期's port still can be drank，但是有几点还是要需要注意的是。那就是bottle cap is not to open, want to keep bottle inside's juiciness sealed in the bottle body, this way can better keep port's taste. And also once opened a port bottle cap should hurry up drink it, or else will happen some flavor changes, this just lost the value of port itself.

If you want to make port's taste more lasting can put the juice in some relatively dry places, not too dry. This is because too wet may cause the juice go bad.

Also one point is cannot put it under sunlight for direct sun exposure like that will be exposed to ultraviolet rays which will cause internal temperature of the juice rise and thus cause the juice go bad. So remember when storing your own bottles of wines keep them away from any kind of UV light sources and avoid dampness and don't open caps either so as to maintain aroma of your wines.

In short while a Port Wine has gone past its expiration date it is still okay for drinking but only with some change in taste. Mainly pay attention to these storage methods then we all can enjoy our delicious Port Wines.
