Sediment drops at different speeds. If you're not seeing any sediment at the bottom of your container after 2 days, you can continue to let your Brewsy cold-crash until you see sediment. Several more days of cold-crashing before racking won't hurt your Brewsy.
Try not to wait more than 5 days, though, because if your wine sits on top of the sediment for a long time, the sediment can impart off-flavors that might affect the final taste of your wine.
You'll start to see a layer of sediment gather at the bottom of your jug. This is dormant yeast, bentonite (a volcanic clay that helps clarify your wine) and used-up yeast nutrient.
