i have been tryin to make a new starter since my old one died on my and when my starter was still in the growing stage i added a bit of sugar to "lift" i up a bit and well now it is quite active and doubles in about 8 hours and is less than a week and a half old. i havent baked with it yet but the day after i added the sugar it started to smell like bananas! sincei have a interest in homebrew beers and i know that this is a character appropriate for the beer style hefewiezen, which has some clovy and banana notes in it. also since my starter is a whole wheat starter at 100% hydration i think maybe that the same strain of yeast the resides in the hefe jumped into my starer from the sugar and gave me some banana? has anyone encountered this before? if so how did you deal/fix it or will it be fine?
