Gprokeg reusable beer kegs

an innovative, most safe/cost effective/portable pressure source system (electrical mini pump) for the Gprokeg plastic kegs, no CO2 and big gas cylinder needed anymore; thanks to the multi barrier technology in the kegs, the compressed air never goes into and contact with beer.

We know the light and oxygen is the enemy of beer storage, the finished beer must be stored without light (especially sunshine) and oxygen; but also some people talking about that the finished beer must be kept under low temperature, even with some data for explaination, talking about, for every 10 ° C (50 ° F) increase in temperature, the related chemical reaction rate doubles, beer stored at 100°F for one week tastes as old as beer stored at 70°F for two months, or as old as beer stored at 40°F for one year……but also some different opinions, the typical one is for the IPA, it was designed in the late 1700’s to withstand the long journey by ship from Britain to India, which meant spending up to six months in hot climates. Rumor has it that this “hot maturation” process created a beer that was so good, it became popular back in Britain, is it possible that the technologies of beer brewing and storage now even not as good as the one of IPA in the late 1700’s? also some people did rela...

There are many different type of plastic kegs on the market for beer  packaging this decades, they are light weight, cheap, no need washing/cleaning/sterilization, etc., with high barrier performance to O2 and CO2 for long shelf life, most of them for one-way use and don't need to be returned, no worry of keg lost, etc... which is quite convenient for the breweries. Most of such kegs are intent to replace the stainless steel beer keg, and actually, more and more plastic kegs are using for beer packaging on the market now, but as most of such plastic kegs are for one-way use, the unit packaging cost (packaging cost per liter beer) is still higher than the one from stainless steel kegs, and the main issue is that, some of such plastic keg is not as safe as the stainless kegs, it limite the using of such plastic kegs for the beer packaging. As have to lower the cost of such plastic keg as much as possible, so that it's competitive to the stainless steel kegs, most of such plas...
