How To Choose The Best Cork

Cork is manufactured from the bark of the cork oak tree indigenous to Portugal and Spain. It takes many years for cork oak trees to yield quality cork. This is the reason why good cork is so expensive. When it was first discovered that cork could be used as a closure for wine bottles it was a boom for the industry. Vintners could now bottle their wine and store it over long periods of time without fear of spoilage. Cork is the traditional closure for wine, but experts will tell you that it may not be the best closure available. Modern synthetic corks and stoppers make a better seal and virtually eliminate the off-flavours sometimes associated with natural cork. There is a major thrust by commercial wineries to find a suitable replacement for cork. Bad cork is costing them millions of dollars a year in spoilage. You can expect to see more wineries using synthetic corks in the near future as high grade cork becomes harder to find. Unlike commercial wineries, the cost of using cork is not a big factor for us. If we get a couple of “corky” wines we are only out a couple of bucks or so. It is also possible that as commercial wineries move to alternative closures there will be more reasonably priced quality cork available to amateur wine makers. So home vintners can still partake in the pleasure of pulling a real cork from their bottle of wine without much trepidation. At Brewery Lane we carry two types of cork– agglomerate and solid. We are also testing synthetic corks which we hope to make available soon. The agglomerate cork is composed of granules of cork glued together. There are two grades available. Regular agglomerate corks are inexpensive and intended for short storage of less than 1 year. Winery agglomerate corks have been designed for commercial wineries and can be used for storage of up to 5 years. Solid corks come in two types; collimated and natural. Collimated corks are solid corks that have been filled and polished to cover defects. These are intended for short term storage of 2 years or less. Natural cork is solid cork without any cosmetic finishes. Natural cork can be found in several grades and can be used for storage of up to 10 years or more depending on the grade you choose. So the decision is really yours. If you intend to keep your wine for only short periods of time, say 6 months or less, then it really does not matter which type of closure you use. The type of closure becomes more important if you intend to age your wines. Over the past 2 years I have been conducting an experiment. I bottled a batch of wine using different corks. The results have been quite revealing. I found that all the wine bottled using lower grade agglomerate and collimated corks to be inferior and sometimes undrinkable after 2 years. The same wine sealed with winery agglomerate corks was quite good. The wine sealed with high quality natural solid cork was the best and seemed to have a smoother character. My advice is to use the best cork available if you intend to age your wine for extended periods. You may also want to consider synthetic corks.


HOT TIP!

Running out of wine rack space? Use your cartons.

It happens to every wine maker. Our enthusiasm for the hobby usually results in an abundance of wine. When this happens we often run out of wine rack space. In a pinch you can use the carton that your wine bottles came in. Make sure that the carton still has its dividers intact. Just fill the box with your bottles of wine and turn it on its side. Presto! An instant wine rack. Note: this is only good for temporary storage. As soon as you have wine rack space available you should use it. If you take bottles from the box while on its side it will become unstable and may topple over. This could result in loss of precious wine.

Your Questions Answered

How can I keep wine diamonds from forming in my bottles?

“Diamonds of Wine” develop when tartaric acid combines with potassium metabisulphite to form insoluble crystals of bitartrates. This happens over a period of time and is accelerated by cool temperatures. These crystals usually form in high quality juices and concentrates and they help to soften the wine by lowering the tartaric acid content of the wine. You have to chill proof your wine before bottling to minimize the “diamonds”. This is accomplished by storing your carboy of wine in an old fridge or cold garage for 2 to 3 weeks and then racking the wine off the crystals before bottling.
