Recent customer questions regards sediment in wine, what causes it, and does it alters taste. There are multiple articles on the Web, mostly pertaining to wineries, but how about ferment on premise?
Basically, there are two types on sediments, the first occurring during fermentation. This initial sediment is formed at our premise, and consists of dead yeast cells, proteins, and other solid matter that settle to the bottom. After 3 weeks, we actually stir these elements back into the wine so it can develop more character and complexity. We then let the sediment settle to the bottom, and filter the wine with a medium filter pad. This clarifies the wine without stripping out small particles that enhance flavours (there are 3 filter pad sizes).
The second happens in the bottle. Certain red wines, especially our Italian Amarone will have sediments. These sediment which develops in red wine bottles and is formed from tannins and other solid matter that gradually falls to the bottom (or side, if you are storing the wine properly). The presence of this material helps give the wine character and complexity, but there are strategies to pour wine without sediments.
A common strategy is to store the wine label upward, so the sediments can settle to the other side of the label. When serving wine, slowly bring the bottle upward, uncork, then pour with label upward. The sediments would stay in the bottle.
