A paper written by Mr. Walter A. Riley, F.C.S., a Fellow of the Chemical Society, was presented on January 22, , regarding the history and use of corks and stoppers in bottles, at a meeting held at Brewers Hall, Addle Street, in London, England. Mr. Riley stated in that paper, 'a great many methods have been invented for the purpose of closing bottles containing wine, spirits, beers, cider'and of these, the only ones in use commercially are corks.' He continues with, 'Although cork is perhaps one of the least known substances with which we come into daily contact it is yet one of the most important items in the bottling of wine, spirits, beers, and mineral waters.'

Riley reveals that in his research the first mention of cork was in the mid-sixteenth century and says it was 'principally used for making soles,' continuing with, 'in fact, we can find no trace of its use as a stopper till the seventeenth century, when it is said that a monk name Dom Perignon was the first to use a close-fitting cork.'

After reading his paper, one ascertains that about was when stripping the bark of a live oak became a regular and recognized procedure, and this process began to supply the world with cork. In , the Department of Agriculture in the United States distributed a large quantity of cork-oak acorns to various points in the south Atlantic and Gulf states, in the Southwest, and throughout California to determine if the species could be successfully grown in America. By , 10,000 seedlings of cork-oak were distributed to these same regions hoping that in the near future America would commercially cultivate cork and become a country to add to the list of countries mentioned in the following list.

By , the chief cork-producing countries had forests with production as follows:

  • Portugal: 750,000 acres
  • Spain:  625,000 acres
  • Algeria: 702,500 acres
  • France: 371,250 acres
  • Tunis: 205,000 acres
  • Italy: 200,o00 acres

Wine bottles get corked, with corks made of cork. This wasn't always the case; but when it became important for better wine storage and delivery, the dilemma to be solved was: how could one insert and fix a cork into a wine bottle easier? Challenging, but during the nineteenth and twentieth centuries when winemakers bottled their own product more often than not, they found they needed tools or devices to assist with the process.

The cork needs to be inserted into the bottle in an easy and safe manner. Inventing a tool to insert a cork into a bottle in a single motion would involve placing the cork in the mechanism, positioning the bottle correctly, and pulling the lever(s) down until the cork was fully inserted. The main difference between these corking tool inventions throughout the nineteenth and twentieth centuries, comes down to speed.

Several different inventions were designed to create tools to assist with the conundrum. All of these inventions provided a way to cork a bottle one at a time. As one can imagine, the process to cork a bottle took a great deal of time, eventually being replaced by an assembly-line approach to bottling. Nowadays, there is a wide range of wine corkers from semiautomatic corkers, push button corkers, and vacuum corkers. The small home winemakers still may use in many cases, these early designs that are described in this article.

To start with, cork corks are known for their elasticity. That is, they can compress to about half their width without losing any of their flexibility; which makes them good closures for wine. Corks are usually cut larger than the opening of the bottle they are going into. And, they are also usually compressed before being inserted into the neck of the bottle.

The earliest corking tool in the Wine History Project collection has a patent dated circa , and the latest corking tool is from the s. The Wine History Project collection has obtained five different types of these early cork inserters, sometimes also known as corkers or drivers:

  1. Hand-held wood
  2. Sit-down wood bench
  3. Bench style
  4. Hand-held metal
  5. Double-levered, scissored hand-held

Earliest United States Patents

Patent #35,385, 'Corking Bottles' by Redlich Manufacturing was patented May 20, . The label, which was glued to the early corking bottle tool stated,
'Redlich's Apparatus for Corking Bottles. H. Redlich Inventor. Instructions: Soak the cork, drop it into the opening then hit with a mallet or hammer. Redlich Manufacturing Co., Chicago.'

Redlich Manufacturing Co., was owned by Otto Henry Redlich, Jr., William F. Redlich, and Rudolph Redlich that were in the business of corks, faucets, etc. Their location was 375 -377 North Clark in Chicago, Illinois as listed in The Lakeside Annual Directory of the City of Chicago which was a complete general and business directory, miscellaneous information, and street guide published in , compiled by Reuben H. Donnelley, and printed by R.R. Donnelley & Sons, Printers, The Lakeside Press. An index to advertisements in this directory acknowledges that Redlich Manufacturing Co. was in business as liquor dealers.

Fifteen years later, The American Brewers' Review, Volume 16 dated July through June , where an advertisement appears on page 27 that states Redlich Manufacturing Co. was established in , and at least by the advertisement in this directory, O.H. Redlich, Jr. and Rudolph Redlich were then owners of a bung and cork business, which was located at 2 to 12 Oak Street, Chicago, North 479 dealing in brewers' clarifying shavings and chips.

American Brewers' Review, page 105 dated January ' December , lists Redlich Manufacturing Co., of Chicago; incorporators Otto H. Redlich, Jr., Bernard S. Schoffel, and Alexander E. Redlich, with a capital stock of $250,000 and in the business that manufactures bottlers' supplies.

By July , according to The Western Underwriter, a weekly newspaper of insurance, the business in Chicago was now referred to O.H. Redlich Manufacturing Company.

Another method for this hand-held device was patented August 25, as, 'Apparatus for corking bottles' and was invented by John Sommer, Jr. (-). This tool was identified as the BEST STAR model.

As of November 14, , the Sommer Faucet Co. was located at 355 Central Avenue, Newark, New Jersey and owned by John Sommer, Jr.

TYPE #2 SIT-DOWN WOOD BENCH BOTTLE CORKER/INSERTER

French nineteenth-century corking machines on mortise and tenon framed wooden stands were popular during this time period. There were used for for both champagne and wine bottles. The Wine History Project has in its collection one from San Francisco. It has a long handle that sends the plunger into a hole. The plunger handle is lowered. There is a gear located under the machine for raising and lowering the round base that holds the bottom of the bottle. Someone would have sat on this at the winery, corking each bottle as it was handed to him.

The Wine History Project's wood bench cork inserter combines the wood bench with a take on the stand-up bottle corker. See illustration /patent description of a cork driver patented in .

These corkers compress and drive the cork just like the hand corker, but they do it in one single action. You load the cork and pull the handle. As you start to pull down on the handle the cork is being compressed. Then at the end of the handle's throw, the cork is driven into the wine bottle. This single, swift action makes the corking process move along a bit faster.

Although it may appear to be complicated, it is actually quite easy to use. Bottles are placed on the platform one at a time and a weighted lever cranks down to insert the cork. The lower basin collects any wine that may spill over in the process.

7 Tips: How To Use A Wine Bottle Corker Like A Pro!

Want to learn how to use a wine bottle corker? Then here's some information that you will definitely want to take a look at'

Just as the name sounds, a wine bottle corker is a tool that is used to insert a cork into a wine bottle. It compresses and plunges the wine cork. Below are some tips on how to use a wine bottle corker and how to get the cork into the bottle with minimal effort.

  • Use The Right Corks:
    First and foremost you want to use the right corks when bottling your wine. Without the right cork your bottling efforts will be doomed from the start. This means using either a size #8 or size #9 straight cork. Anything smaller and you can expect some seepage when the wine bottles are laid on their side. Anything larger and the wine bottle corker will have too hard of a time corking the bottle. As a side note, you'll also have an incredible time getting the cork out.
  • Prepare the Corks:
    The wine bottle corks can be prepared in one of two ways:
    1. You can steep or steam the corks in hot water for a short period of time. Bring a pan of water to a boil; turn the burner off; put the corks on the water; and place a lid over them. About three minutes is all the time recommended. Never go over five. Get the corks off the heat. Heating the corks for too long will cause the them to become brittle and crumble while in the bottle.
    2. The second method is to submerge the corks in a sulfite solution for a few hours or overnight. You will need to use a container with a lid to keep the floating corks submerged. I use an old plastic jar. The sulfite solutions consists of either 1/4 teaspoon of potassium metabisulfite or 4 Campden tablets in a quart of water.Regardless of which method you use, you will want to drain the excessive water from the corks by placing them in a colander, strainer or something similar.
  • Loading The Cork:
    Now we're getting down to how you actually use the wine bottle corker. This step is very straight-forward. Each corker is a little different, but essentially all you are doing is dropping the cork into the corker's chamber.
  • Compressing The Cork:
    What this is doing is taking the cork that is almost an inch in diameter, and squeezing it down to  about the diameter of a dime. Depending on the corker, this action requires that you pull down or squeeze some kind of lever.
  • Inserting The Cork:
    This is where the actual corking takes place. Once the cork is compressed, a plunger is used to slide the cork into the wine bottle.  Some style of corkers compress and plunge all with one lever action. This is normally the case with floor-standing wine bottle corkers. Other corkers may require two steps as described above. First you compress. Then you plunge. This is sometimes the case with hand-held corkers.
  • Adjusting The Depth Setting:
    Once you cork your first wine bottle you will want to take a look and see how far the cork was inserted into the bottle's opening. The goal is for the cork to be flush with the top lip of the wine bottle opening. A little lower is okay, but you never want the cork sticking out of the wine bottle. Most wine bottle corkers will have a depth setting adjustment that will allow you to control how far you corker plunges. Play with this adjustment until the corks are being inserted at the proper depth.
  • Seating The Corks:
    All wine bottles that are sealed with a cork in this way will eventually need to be stored on their side. This helps to keep the cork swelled so that it can continue to maintain a tight seal. But before laying the bottles down you need to give the corks time to set. After the corks are compressed by the wine bottle corker, it takes a little time for them to expand all the way back and apply full pressure on the inner side walls of the wine bottle opening. If the wine bottle are laid on their side too soon some could leak. For this reason you need to let the wine bottle sit upright for a day or two before stowing away in the cellar.

So there you have it, the essentials of how to use a wine bottle corker. All-in-all you'll be surprised at how simple it is to cork a bottle of wine. It's a fun part of the wine making process and one that's just perfect for getting the whole family involved.
