What to Do About Sediment in Wine


Have you ever gotten to that last sip of a glass of wine only to get a mouth-full of sediment? Instead of savoring that last sip, you end up spitting it out. An unpleasant way to finish.  And that's what recently happened to me as shown in the photo. But it doesn't have to go that way.

As discussed last time, lees (dead yeast cells and bits of grape seeds and solids) are natural in the wine making process and often desirable to be left in the wine during fermenting or aging.  This process is most common in red wines. Some wine makers will then filter out these solids (fining or racking), but others prefer to leave them in the wine as it's bottled to continue to add flavor.

There are several ways to avoid getting a mouth full of these particles in your glass of wine.

The first way is try to keep the solids in the bottle and not in your glass. If the bottle has been standing still and upright for a couple of days, the solids will have naturally fallen to the bottom of the bottle. As long as you are careful to not stir them up while opening the bottle and are gently tipping the bottle while pouring, the sediment should stay in the bottom of the bottle. But why take the risk.

The most dependable way is to do your own filtering before serving. There are several inexpensive devices on the market for doing this. The best one is a combination filter/aerator funnel. You simple hold this funnel above your decanter (or any other suitable container) and pour the wine through.  It has a micro-fine filter built-in that traps all those undesirable particles while allowing all the wine to pass through. As the wine exits the funnel, it gets aerated (exposed to air) which will usually help a young red wine. You'll then find all those undesirable particles trapped in the bottom of the funnel.  Not lurking in your wine glass.

While sediment is not harmful if consumed, it does significantly detract from a nice glass of wine.  So, filter and forget! Cheers!


Is there an Egg in Your Wine?

It may sound like an odd question; an egg in wine?  Winemakers use many different products to fix flaws and flavors. But it usually difficult to know which ones have gone into your glass.

There’s no law requiring bottles to be labeled with
these ingredients, and it seems that most winemakers don't want to disclose that information.

Among the things used in wine making are animal products including isinglass which is derived from fish bladders, casein which comes from milk protein, gelatin and egg whites. So, in fact, there may have been egg in your wine before it was bottled.

Egg whites are just one of the products used in the process called 'fining' of red wines. Adding a solution of egg whites and water to the wine as it ages initiates a process that removes solid particles by binding to loose particles in the wine and causing them to settle out so that sediment can be easily removed before the wine is bottled. The fining agents are typically undetectable in the final product, with only trace amounts remaining.

The result is a stable, clear and pleasant-looking glass of wine instead of something that would otherwise be cloudy-looking.

Here's to raising a clean and clear glass of red wine. Cheers!
