What Size Corks Should I Get For Bottling My Wine?

If you're getting ready to buy corks to bottle your wine you may be wondering which size you should get. We offer four different sizes of wine cork stopper. They are sizes: #7, #8, #9 and #10. These numbers refer to the diameter of the cork. The higher the number, the larger the diameter.

The opening of a standard, 750 ml wine bottle is 3/4 of an inch. If you have a wine bottle corker you will want to purchase either the size #8 or size #9 corks. Which size you get depends on the type of corker you have.

Any wine bottle corker on the market can put in the size #8, however some corkers have trouble putting in a size #9. If the corker was purchased from E. C. Kraus, you will be able to put in a size #9 cork just fine.

If your corker was purchased from somewhere else and uses a funnel-design to compress the cork, you will need to use a size #8 wine cork. The commercial wine industry uses a size #9.

Size #7 corks are for individuals who want to put their corks in by hand. We do not recommend using this size for this purpose, but if you do, you will need to store the wine bottles up-right instead of on their side to prevent leakage.

Size #10 corks are for larger size bottles. While many larger bottle still have the same 3/4 inch opening that the 750 ml have, some do have a larger opening that will require this larger size cork.
