    Carbonic Acid

    Carbonic acid is created when co2 goes into solution. So would all the acid leave solution if the beer is allowed to go flat or would some remain? For example a beer is over carbonated and then carbonation level is lowered. Would that beer have a higher carbonic acid level than the same beer...

    Ibu's From Non-hop Sources

    Urn(ish) Design

    Hey all, I have been throwing around some ideas for a compact BIAB system. I live in an apartment that is at its crap capacity, so small is essential. I do occasionally run a regular old all grain system with my dad at his place but finding free time to go visit is an issue once you add...

    Lillipilly In Brew

    A few question in one post. 1. Has anyone tried using lilly pilly's in a brew? If you have: 1.a.) how did they turn out? 1.b.) how potent are they for flavoring a brew (i.e how much did you use) Not having any fresh fruit available (out of season) all i have is some home made lilly pilly...
