Thanks! Since fermentation is accelerated, by the time I took the next sample and let it degas I was already at 69% attenuation. At that time I took it out of the fridge and letting it rise to my basement temp around 66. I plan to leave it there for about a week and plan to ramp up the PSI to my desired carb level.

How did the ramp go? Did you get up to wanted CO2 volumes? Just curious how well it worked for you.

Using Beer Plugs® (15PSI gauge or 30PSI absolute) on 3-liter SODA bottles work great for pressure fermentation. They are special caps that vent pressure above a threshold with high quality, inexpensive one-way valves. Soda bottles (which will hold over 100PSI) make great pressure vessels. The Beer Plugs® were mainly designed to use in the racking/finishing stage for those who bottle prime. But you can get them for the 3-liter PET soda bottles #AND# you can get them for glass growlers. Both are much less costly than pin-lock or ball-lock cornies, which'll be around fifty bucks most anywhere. Here's how they work: http://www.youtube.com/watch?v=SrkRy...ature=youtu.be

Would one of you who ferments in an unmodified sankey be willing to detail your yeast washing procedure for me?

I have been making a larger starter and saving some of that, but I would like to be able to save larger quantities from my lagers to minimize the number of starter steps I need.

Good product for what it is designed for, but fermentation??? Even at 3 liter that is way too small to be effective. Great bottle conditioning idea though.

Easy, slowly let out the pressure in the keg once beer is transferred. Then I used a coke bottle with bottom cut off for funnel on the beer port on the connector to fill with sterilized water. Once filled, shake keg and push out all the yeast you can into your collection vessel. Now wash as normal from this point on. Slowly releasing the pressure is key or the yeast will explode.

What do you mean when you say slowly? Over an hour? A day?

How much water do you typically add?

Thanks.

An hour doing a psi every few minutes. I add whatever water I plan to do the initial was with. Usually this is about a gallon.

This thread inspired me to build my own setup! Just thought I'd post my build for everyone.
