Working in a glass manufacturing business that sells bottles to wine companies

After two months of unemployments, I found a job which manufactures glass bottles from scratch, literally from sand. Then they manufacture different sorts of empty glass bottles. They sell the empty bottles to juice companies like Snapple’s, Ketchup companies like Heinz, etc. More than 40 percent of their customers orders are from beer and wine companies which I found out later. Should I continue working here? I work in their software IT division.
