Tried to make a Pina colada mead following city steading brewing's recipe, accidentally bought coconut milk instead of coconut water and found out only when everything was sanitized and pineapple juice already in the fermenter, and thought "what the hell, what the worst that could happen? If it goes rancid I'll just dump it out", we'll, I woke up to a lovely Pina colada smell and my kitchen absolutely covered with goop and air lock in the other side of the kitchen. Learn from my dumbassery.
Ah - that's happened to me before. Making banana wine, crushed and boiled my fruit selection, didn't filter it very well before fermenting, blocked the airtrap in my demijon, first I knew about it was an almighty bang and then I had to repaint the kitchen.
Joy of homebrewing, am afraid. Sometimes you do stupid things and they turn out amazing, and sometimes you do sensible things and just forget one tiny but essential step. I heartily recommend making snakebite-and-black homebrew, btw - lager kit, cider kit, couple of bottles of blackcurrant juice all in your fermenter; loses all its sweetness and most of its purple colour and the result is a very tasty brew.
Thankfully I don't have to repaint anything, and I wish I could try that but blackcurrant is not available where I love
