    When priming with sugar or Dry malt extract or gyle (speise) is yeast added-in with it or does one always rely on the tired yeast already present?

    Second, is this technique only used for bottle conditioning or is it an option in commercial breweries to who wish to naturally carbonate their beers?

    Thanks

    Most homebrewers rely on the tired yeast present, BUT if it is a high alcohol or long aged beer, we may use fresh yeast, which might even be a different strain from the yeast the beer was fermented with. Lallemand CBC-1 is very popular for this.

    To my understanding, most commercial breweries that bottle condition add some fresh yeast at packaging. There's to much riding on a consistent product to rely on tired yeast.

    Thank you MrOH
    I needed to understand whether breweries use this technique to referment beer in bulk (like krausening) and them capture the carbonation (in a pressurized tank), followed by filtration and bottling?

    I know that some larger breweries capture the CO2 from fermentation and add it back in at packaging, but I'm not sure that's what you're asking.

    Commercial breweries who seek ‘bulk’ carbonation do not have to add fermentables (e.g., priming sugar, DME,…). They could choose to just implement spunding. Here is a link to the process of spunding on the homebrew level:

    The principle is the same at the commercial scale.

    Cheers!
