Not enough happening, hoping that a slight increase in temperature will get things going. Ambient temperature in office 19.1 ℃ (vessels measured at 20.4 ℃ with infrared thermometer) when I moved them at 21:45.

Right now the Thrush isn’t doing very much, there’s some very small static bubbles that look like they’re from fermentation stuck near the top, but generally the yeast has just expanded a little to form a weird carpet on top, with some chunks linked together and staying still, suspended in at various heights.

The Turbo is more exciting to look at, with a similar but slightly thinner carpet on top and individual yeast flakes continuously falling and rising for the whole height of the brew in some kind of bidirectional cascade. More bobbles on top also, with the airlock popping every 15 or 20 seconds.

Next Day

The vessels have come up to temperature and the infrared thermometer reads 21.6 ℃ while the ambient temperature is around 21.9 ℃. This doesn’t appear to have done much for the Thrush, which is still as static as yesterday, but the Turbo has gone up a notch and there’s a steady stream of bubbles audibly making its way to the surface. Airlock is popping every couple of seconds too.
