Wine
Some wines lend themselves to aging, but not all wines get better with age. Product labels on LCBO shelves can help you determine if a wine can be aged. If the bottle icon is upright (refer to image), it should not be aged and should be consumed right away. If the bottle is on an angle or horizontal, the bottle is expected to evolve in a delicious way with age. While the labels act as a guide, always do your own research to avoid disappointment.
Vintage-dated Champagne (i.e. Champagne made entirely from one exceptional vintage in a specific year) is intended for long-term aging. Typically, these are made in years with ideal conditions, and will develop in complexity for multiple decades if stored well. Non-vintage Champagnes, however, are intended for more immediate consumption within a few years and are not typically recommended for collectors.
Beyond avoiding spillage, the purpose of a wine bottle closure is to prevent oxygen from getting in, as it will change the taste and quality (a process known as oxidization). Bottles with corks should be stored horizontally to prevent the cork from drying out, which will cause it to shrink and let oxygen into the bottle. If you are aging wine, it’s a good practice to check your wine bottle corks a couple of times a year to ensure that the corks are still intact.
If you don’t have a specialized unit to keep your wine at a constant temperature and humidity, there are still things you can do to help preserve wine: store wine away from direct light and heat, and ideally, in an area with relatively consistent temperatures to avoid extreme highs and lows.
Once opened, an unfinished bottle of wine should be stored in the fridge to slow down the aging process. Wine will have gradual flavour changes day-by-day and will likely last for up to a week. There are a range of gadgets to help extend the life of your opened products. The simplest is a silicone stopper which is enough to preserve the flavours and freshness of an opened bottle of wine for a few days.
