I have been reading recently about the problem of Crown corks with plastic liners "scalping" hop aroma compounds from beer.<br />https://beersensoryscience.wordpress.com/category/oxidation-and-staling/ <br />Some of humulene and myrcene were only recoverable from the crown cap foam material after 56 days with non left in the beer!<br />The wine industry has found a similar problem with artificial corks and found traditional corks faired much better.<br />Maybe the move from making crown liners using cork to plastic was a backward step? <br /><br />JoelJoel Barrowhttps://www.blogger.com/profile/01355157374870384728noreply@blogger.comtag:blogger.com,1999:blog-5445569787371915337.post-32246227931182260162013-10-26T08:52:08.411-07:002013-10-26T08:52:08.411-07:00There have teen two changes in crown caps that hav...There have teen two changes in crown caps that have been made in my lifetime that I am aware. Some years ago, a disk of very thin foil was added to cover the bare cork disk. More recently, the cork was done away with entirely and replaced with a ring of compressible plastic.<br /><br />When I was a boy, we would occasionally entertain ourselves by making "badges" with fancy colorful crown caps. We'd carefully pry out the cork disk, put it inside our shirt and press it into the cap on the outside of the shirt, trapping the fabric between the two. This worked best with a thin fabric such as a tee-shirt.<br /><br />We were easily entertained back before 300 cable television channels. ;-)Jeff Rennernoreply@blogger.comtag:blogger.com,1999:blog-5445569787371915337.post-18859578002404878342013-10-26T03:46:53.268-07:002013-10-26T03:46:53.268-07:00It's used to this day with great success. It&...It's used to this day with great success. It's one of those key inventions, like the wheel (almost) or zipper.<br /><br />The only caution I can remember reading is in the article you reprinted here which we discussed called Cyril Ray Cracks A Bottle of Russian Stout, from the 1960's. In that article, Ray, a noted wine and food writer, commented that Brian Guinness, scion of the famous brewing clan, told him that if you seal the tops of bottles of Courage IRS with wax, it "gets under the skirts" of the crown enclosure and will preserve the beer longer due to cutting off ingress of oxygen. (Ray wrote after that, "if you'll pardon the expression", which is the kind of decorous touch you don't find as often today).<br /><br />They knew some oxygen gets in and some bottles closed in this way will lose oxygen over a very long period, but one not material for normal purposes.<br /><br />Modern crown corks often get a white plastic undercoating which is supposed to absorb oxygen in some fashion, but whether this really works I cannot say.<br /><br />I often keep bottles in the fridge a few days after opening, to drink later or to use in blending. (Last night I made a three treads again, a very dry craft stout which is of that generation here that followed the post-1950's Guinness model, a rich Imperial Porter and just a splash of a very soy-like (probably overage) Guinness Special Extra Stout. Darn good result if I may say). I just crimp back on the crown caps, sometimes using one from a different bottle to make it tighter, and it works just fine. Or more commonly I use a wine or whisky cork. If the beer loses carbonation this is all to the good usually but I'm talking of just a few days.<br /><br />GaryGary Gillmannoreply@blogger.com
