Yeast require oxygen for growth, make sure you always have some available to oxygenate your wort prior to pitching!

• This 20 cubic foot O2 cylinder is good for about 500 batches of beer.

Hate having your disposable oxygen tank run out right before you were about to pitch your yeast? Or just tired of running through disposable tanks in general? Consider stepping up to a refillable oxygen cylinder. Whether you brew big batches or brew frequently, a refillable oxygen tank is a great way to save time and money.

The tank needs to be hydrotested every 10 years and is easily and affordably filled at any participating welding gas company.
