I'm at the point of racking a LE17 Chardonnay Chenin Blanc after 14 days and I was surprised the see the amount of sediment in the primary fermenter. Roughly 3 liters (0,8 gallons)! That is far more than I ever seen! Anyone else seen something similar? Don't know if it's due to juice itself or the new Winexpert bentonite in bigger quantity,
For what’s worth, keep in mind that bentonite is a clay mineral that has long been used in oil drilling to put sediment into suspension and keep the hole open.
There are at least two types of this platelet mineral, and probably variations, but sodium and calcium are the main cations. If the bentonite slurry is not circulated, the sediment settles to the bottom, slowly, and the hole may collapse. In our case, we want this settlement.
Most of the sediment we see is the remains of microorganisms that fulfilled their mission and died after converting their food supply, sugar. It stands to reason that if more sugar is available, such as kits that contain more juice, then there will be more organisms in the slurry.
Until one of us comes up with a centrifuge for carboys, or a larger filter press, sediment will always be present, which is not a bad thing. Micro filters can be used, but they are expensive; extremely expensive in the water treatment industry.
Perhaps WE has a new source of bentonite or the yeast strains are more enthusiastic over more juice. I used the same LE Chenin Blanc/Chardonnay kit recently and noticed more sediment. But I view that as a good thing.
