” Rav Abadi is a posek in Lakewood. “
According to his web site, he’s been in Jerusalem for a while. Anyways, I asked a friend of mine, who works for the OU, about Rabbi Abadi. He told me that Rabbi Abadi is a tremendous scholar, but lacks industrial kashrut knowledge. The following is an example of that.
I looked at his (really their – including Rabbi Abadi’s sons) web site and found a “teshuva” where he (not sure which one) said that since wine is all processed by machines, then there is no need for “kosher” wines. That answer was dated 2002. I asked a friend of mine about it. This friend is a ger whose family makes non-kosher wines. He told me that they indeed handle the wine, test it, etc. I went back to the web site for further research and found a retraction of that teshuva dated 2003.
Back to the original question. The ideas expressed given by ilovetorah are what I would say.
