Hi everyone,
We are looking into a 6-head semi-automatic bottling machines (see picture below), using counter pressure filling with air pre-evacuation. However, such machines do not have any fobbing capability, meaning the neck of the bottle will not be purged of air prior to capping. I’m quite concerned about oxidation in general, especially considering the hot climate where we are, and our wish to produce beers that may benefit from some aging in bottle.
Are there any DIY methods for causing some foaming inside the bottle just before capping? E.g. a tapping mechanism, or vibration or some way of dropping in a drop of liquid nitrogen?
Or maybe I am overestimating this risk, and there is enough foaming when releasing the counterpressure to help purge air in the neck?
We are fortunate to have a local engineer who custom-makes such machines, but if you have any suggestions of a good (relatively cheap) supplier of similar equipment, we are all ears.
Thanks for your help,
Dieter
