The other day, I was with my friend getting ready to bottle a batch of modified cream ale (our second homebrew so far). We were using an auto-siphon to transfer beer from fermenter to the bottling kettle, however at some point I had to use only a hose to transfer (don't ask). So I took a mouthful of vodka, gurgled in my throat vigorously, spit out, then pulled on the hose to start pulling the beer out of the fermenter. Not being cautious, a little bit of beer ended up in my mouth, and before I managed to swallow, I accidentally spit it out straight into the kettle.
So we had a good laugh about it and proceeded with bottling, but I kept on wondering whether this event can alter the beer in the end. I will know for sure what happened as soon as I open the first bottle after conditioning (will add updates here). Did anybody have any similar experience or know how any mouth or stomach borne bacteria may affect the beer during conditioning. My relief is that the beer is quite alcoholic (7.9% ABV), is quite hoppy, and has 1 oz of grated ginger in last 15 minutes of boil, so hopefully the flavor won't change much.
I am a 27-year old, healthy, male human.
EDIT: We just had one after a week of bottle conditioning. It is excellent. Can't wait to have some after few more weeks of conditioning. Thanks all for great answers, especially the siphoning tips, it will sure improve my brewing.
