This is the answer to a wine maker’s prayers. VA Filtration’s ‘Sweetspotter’ is a single barrel, or small lot nanofiltration treatment solution that can test and treat a wine for Volatile Acidity, Ethyl Acetate, Brett (4EG.4EP), smoke taint, green character etc. The limitations of high pressure pumps had made this impossible… until now. Our latest machines are available in vertical configuration with the option of automatic batch control.

What’s unique about this system?

The Sweetspotter uses the pressure of the outgoing wine stream to pressurize the incoming wine, driving a set of pistons. The system’s operating pressure sets and adjusts automatically, which means less power is required to run it. What could be simpler, and gentler, on your wine?


We supply replaceable membrane media cartridges for VA, EA, 4EG/4EP & other taint reduction with your Sweetspotter. Return used cartridges and we’ll supply fresh ones. Columns are also available.


You’ll like this. With a wine at 60ºF and less than 0.5% RS, an average reduction of 30% can be achieved in 60 gallons after around 3 hours of processing using the SS4-1-10.SS4-1-10Rev3FrontISO

Faster Processing?

Then you need SS4-4-40. It will treat your wine approximately four times faster than the single element SS4-1-10.
