Good Cheap Co2

Hello
Recently I have been thinking about how to completely seal my co2 in the bottle, if you go to a local winery were they sell the yeast and supplies for wine making you can get a wine bottle and rubber cork with a hole in it. With a piece of airline tubing in this hole it is completely sealed, also the mixture changes is much easier. While your there ask the people what kind of sugar creates the smallest co2 bubbles ( there is a big difference from home sugar to this stuff ) I believe its called barley sugar. Works Great and came out to about 10 bucks for everything.

So here is the finished product, it is already creating about 3-4 bps and has enough pressure to push through the smallest air stone. I used corn sugar and wine grade yeast in a 1.5 bottle ( all supplies can be bought at a wine store ) I highly recommend the corn sugar and the hardy wine yeast.

I used to use their yeast, it was the good stuff that was better than average. However it goes bad fast if you dont put it in the fridge.

They also recommended brown sugar which I always used.

Im moving away from DIY though, I hate waiting for the mixture to start

Started using DIY co2 few years back. Switched to pressurized too, as waiting for the mixture and messing with it was more time than I had.

Neat. That seems safer, then a coke bottle. How is the pressure holding?

Pressure is holding really good, still around 3 bps, its a lot less troublesome then the past co2 systems using all types of coke bottles. I think it was really worth the extra buck for the corn sugar bubbles are coming out of my air stone this size of small dust
