I know that there was some concern about degassing a kit with a vacuum pump. After manually degassing a Pinot Grigio Kit for what seemed an eternity, we decided to use the All In One Wine Pump, let me tell you....in no time, we degassed a kit (as per the instruction before we added the fining agent), prior to using the All in One Pump, we had attempted to degass by hand...20 mins into it, it appeared to have no effect at all, still tons of CO2. After seeing just how efficient the All In One Pump was, my buddy ordered one on the spot! It saved a ton of time and effort, not to mention, the kit will clear without the worry of too much gas. I think that one of the things that surprised my buddy was just how much the wine changed after degassing properly, prior to using the pump, the wine, full of CO2 tasted tart, almost bitter, as a young wine will. After degassing with the All In One, the wine actually tasted more like it should, you could taste the fruitiness that we expect from a Pinot Grigio, and only a slight amount of tart. Once again Steve.....Great job my friend!!!!
