If you bulk age long enough, you get more sediment out of the wine. Components that form haze, precipitates and sediment denature over time and fall out of the wine. These sediments are unstabile and not allowing enough time in bulk aging, you still have a wine that is unstable and throwing sediment. Bulk aging is the true way of stabilizing wine.
Now that being said, there is nothing wrong with some sediment--many home winemakers have sediment in their bottles. It's just not real pretty. We almost never have sediment because we bulk age long term. Some people aren't as patient as we are or have the space for lots of long term aging. You should decant the wine into a carafe for guests if the sediment bothers them.
When you make fruit wines with no water, you'll have very dense wines that can throw sediment for a long time--and some of these wines never become totally clear. If that is the issue, then it's time to think about using better pectinases like Lallzyme C-Max which not only rapidly de-pectinizes, but also aids in clarity. And using bentonite in the primary which not only gives you a clearer wine but heat stabilizes the wine so you have better protein stability under storage conditions. We bulk age our blackberry for no less than 1 year--and we even have some in long term storage that is 2 years old.
