I've made a few batches of beer using a different fermenter that wasn't clear but this is my first time making mead so I'm probably making something out of nothing but I had an airlock blow last night which is common i noticed this start forming not long after fermentation began and think it might be partially responsible has anyone seen anything like this before is this krausen, yeast buildup or an infection? It smelled okay when I resanitized and put the bung and airlock back on I just want to identify what this is
