Bottler update:
We are still using the same bottling machine in the video, but I replaced the spring loaded bottoms, with a plain shelf. I can now load two bottles at a time because it only takes one hand to load a bottle.
We have bottled over 50,000 bottles with this bottler so far.
We average 350 bottles per hour. The fastest we have done is 445 bottles in one hour. The machine can go much faster than the capper can cap bottles.
You need to realize, this was our first test with this bottler, done in my driveway.
We bottle 8 barrels at a time, but hope to jump to 15 barrels soon.
We also added another step. we now CO2 purge twice using a purging station.
You can never purge enough. With our new double purge method, we have tried beer over a year old and tasted no oxidation.
Here is the thread he also says he got the instructions from
