I had the same problem with degassing wines even after several years in the bottle until I got the same pump you have. If you use it for each racking operation your wine will be truly still by the time you are ready to bottle.

Best Trellis for Petite Pearl ?
I appreciated the comments here to date.
Has anyone tried VSP on Petite Pearl ?
Any approaches other than High Cordon Trellis that people have tried ?
I appreciate the advice!
