I brewed 'Tripel Round the World' from the Extreme brewing book on Sunday, a 10L batch with OG of 1.090. I made a 1.2L starter for a Wyeast 1214 which was a little dated (9 months), but also ran to get a Trappist High Gravity in case the 1214 showed no activity, and made a starter with that. The 1214 starter has been going since Sunday (48h), the trappist high gravity (24h). No activity in either starter. I woke up this morning to a sour smell , and saw that my wort had began growing a thick brown head, doesn't smell terrible, just a little alcoholic. I panicked because I didn't want it to become spoiled, and threw in the Trappist High Gravity starter hoping it might not be too late to salvage. anyone have any ideas as to exactly what I'm currently going to be dealing with for a beer?
Secondly, I have been nurturing a starter that was harvested from a Unibroue Maudite bottle. Took about a week to show any signs of growth, and have slowly been upping the starter, and it's currently about 4L. Starter tastes just fine, smells sour, it's sitting in the fridge now, but has become pretty vigorously carbinated in the meantime. If the beer tastes fine, is this carbonation the sign of a giant and healthy starter? These are my first experiences with starters, and I'm meticulous about everything being sanitized and cleaned.
thoughts? Should I toss the Unibroue? Is my tripel spontaneously fermenting, and what will be the impact of adding my trappist high gravity starter (that showed no activity after 24h)?
