Clean way to add extra Co2?

[Pedro de Pacas]

Small world!

Did some beef brewing as well aroun' 2005.
It was a lot of work to do right.

Now, I brew surprisingly good wine from costco fruit juices, Hawaiian cane sugar, and D-47 champagne yeast.

Got an airlock on a 5g. fermentation bucket and use a long, 1/4" aquarium hose to pipe the CO2 to the bloomery.

Gives a good rate for a small area, ( 2' X 4'), for about 30 days.
Then I start another bucket.

Bottles of home-made Pomegranate-blueberry, wine make excellent gifts.

Aloha,

I stopped brewing beer a few years ago, but I still have the equipment! Sugar, water & yeast it is...knocking on wood!
