Seen at the MSSF fungus fair.
Lalvin EC-1118 yeast eating sugar in Treetop apple juice. I keep it on my water heater because it stays slightly warm there, but not too warm.
To make the wine I open the juice, pour out a cup, add a cup of sugar, a bit of yeast, then leave the cap on loosely so the CO2 can escape. After a week it stops bubbling furiously and after a month it tastes great. My favorite juice to use is “Blueberry Estate” from Trader Joes, but Treetop apple juice and mango passion fruit are also excellent.
The micrograph is stained with melzers reagent.

I do not recommend fermenting at higher temperatures on top of a water heater, it tastes better when done at room temperature.

Brownish blob in the pond- Yeast is not usually found in ponds, our hypothesis is that it fell in somehow.
