Thank you. While you applaud the idea many others on home brew talk have been not as welcoming to new ideas!
Maybe that was sarcasm regarding his spelling, but otherwise I think you misread his comment....
Either way, I do applaud your spirit of experimenting, but I also agree theres something to be said for knowing the basics before experimenting. It sounds like youre very new to this so it would be fair to say you dont know too many of the basics?
To be clear, since I dont think others have been if youre as new as you sound: adding something sugary, like cupcakes, to your beer to age it will cause another fermentation to start up on the sugars in the cupcakes. If these are commercial cupcakes I suppose theres a chance theyre loaded with preservatives and you wouldnt be at a terribly huge risk of infection, but the advice to cook in the oven for a bit to sanitize would probably be wise.
As far as the driftwood, again I see what youre going for. Cool idea, wouldnt it be cool if you could the saltiness from driftwood into a Gose? And people age on wood already, right?
However Im telling you right now damp wood on a beach (which I assume to be warm) is going to be growing all kinds of nast. If youre dead set on trying it maybe the oven idea would work, or maybe break it up and bit and soak in vodka for a while, but even then youre talking about something guaranteed to be carrying some nasty stuff and putting it into your beer. The feces comment was obviously a little over the top, but the point that you would never put something you expect to be terribly full of microbes into your beer. We sanitize stuff that we put in secondary because we typically start with decent food grade type stuff, but want to be sure its sanitary, not because we think itll clean up exceptionally dirty stuff. Its called sanitizing, not sterilizing, for a good reason.
If you want a driftwood gose maybe just make a gose the normal way and age on some other kind of wood cubes made for this purpose? And a cupcake beer could be achieved by adding sweetness and vanilla or whatever in other ways too.
