Sur Lie Aging Explained

Notice the thin layer of fine lees on the bottom of the barrel.

Sur lie aging is the process of allowing a finished wine to continue to sit on the lees in order to extract flavors. Recently we explored the fact that there are two different types of lees. There are the grape lees (coming from the fruit) and the yeast lees (you guessed it, from the yeast). Each of these can be used in sur lie aging and each will produce different results.

Aging wine on the grape lees is something to be undertaken with extreme care as this lees can easily spoil a wine if not done properly. When done correctly though it can lead to a wonderfully complex wine. Continue reading “Sur Lie Aging Explained”

Gross Lees vs. Fine Lees

Did you know there are actually two types of lees? Not only are there different kinds, but they are actually quite different from one another.

One kind of lees can spoil your wine in a very short time. The other kind has the potential to take a good wine and make it great by adding flavor compounds as well as smoothing out the mouthfeel.

The gross lees refers not to how disgusting the stuff may be but the size of the debris. When you make wine from fresh fruit it is inevitable that some of the grape skins, seeds, and perhaps a stray stem or two will wind up in the bottom of your fermentation container.

It’s this chunky style lees that causes the most concern when it comes to determining how long you can let your wine sit before racking. The gross lees that can leave really funky flavors in your wine in short periods of time. Continue reading “Gross Lees vs. Fine Lees”

Topping Up Your Wine

While oxygen is necessary in the early stages of fermentation it is also the mortal enemy of wine makers once a wine has gone still. Topping up your wine after fermentation is complete is the best way to minimize how much oxygen your wine is exposed to.

As our wines ferment we rack it from one container to another to get it off the lees. Each time we do this though we lose a bit of wine and increase the surface area of the wine we have left. This can leave us with too much head space at a time when our wine is most susceptible to oxygen exposure.

Topping up is the process of adding wine to your carboy, barrel, or tank to reduce the amount of head space (also known as ullage). This serves two very important purposes. Continue reading “Topping Up Your Wine”

Glass vs Plastic Carboys

This debate has been going on since the introduction of plastic carboys made from PET. PET by the way stands for polyethylene terephthalate.
