Now this is an issue. Who wants floaters or sinkers in their glass? What will you say and what will you do. Here is where knowledge becomes power.
Let me explain...the wine is not flawed but is at its natural peak of quality.
What you are looking at is tartaric crystals, referred to as "white diamonds" or in German " weinstein" (wine stone).
You are looking at a flawless bottle of wine but it is not aesthetically flawless wine. The reason you do not see crystals in white wine is that the wine maker uses a cold stabilization process before the wine is bottled. The tartaric crystals flakes fall out and are captured. This process rips the wine apart and changes the wine's colloidal structure.
If the cold stabilization process is not used then the wine will naturally produce the tartaric crystals as part of it aging process. These crystals show that the wine is mature and ripe for drinking with little tartness as the acid has be pulled out with the crystals. You are getting a great bottle of wine. Just don't offer the crystals, they are not sugar. They will be gritty and awful to get into your mouth. Make sure to leave them in the bottle by carefully pouring the wine into the glass.
