I used some 9 x 1 1/2 corks that came with my wine making equipment from Fine Vine Wines. They are the glued together cork pieces type corks. I installed them with a hand corker. To sterilize them I did as Fine Vines videos suggested. I placed them in a colander and placed the colander in a bucket with some kmeta in water. The corks never got wet from the kmeta solution. These things are tough to pull and not consistent. Some come out with more than the difficulty of a commercial wine. Some surprise me that I am able to remove them in one piece. What can I do to fix this?
