Requirements Archives - Cellar Dweller

I would like some information on your juice lees filtration services during harvest. We currently have no lees filtration and have been actively looking for a solution. I know you are doing lees filtration at smaller facilities, but I’m concerned that our volume may be too small for you to handle.

During harvest, we run multiple wineries and multiple batches per day. Our present capacity is 4000 to 5000 liters per shift. There is some wine intermixing from batch to batch, about 100 liters. We accept volumes of 400 liters or greater during harvest, and volumes of 1000 liters or greater during other time periods. For

Does the wine need to be racked? Prefiltered?

One of the main selling points of Crossflow is the efficiency of the system and its ability to handle higher turbidities and produce bottle ready wines in a single pass. Wines do not need to be pre-filtered. If wines are un-racked, we normally start filtration off the racking valve, and then complete the filtration from

Does the STARS unit require a certain “cleanliness” level of wine before STARS treatment?

We specify a maximum turbidity of 5 NTU, but Crossflow or fine filter pads are recommended. The STARS unit has a 1 um absolute filter installed to protect the membranes, this filter is $125 per changeout.
