I hesitated to phone based on reviews. Phoned to ask about instructions for making their cider. The lady who answered went over the process with me and emailed me a copy of the instruction sheet.
Bought some potassium metabisulphite from them and followed the package instructions for sterilizing must prior to fermentation. My wine did not ferment, no matter how much yeast I pitched. After consulting with pro winemakers familiar with the chemical, they informed me that the instructions say to add 4 TIMES MORE than you should. Twice attempted to contact their customer service and zero response. Over $100 down the drain. Don't buy their products. Terrible business practices.
I have done business with ABC Cork for many years and I find them to be very helpful. They carry a wide range of supplies that many companies do not. Their service is excellent and I have nothing but praise for them.
