There’s no sign of life from the starter that’s been spinning for a day or two on the stir plate at 21℃, so I’m going to throw it in and see what happens. The other bucket (with dry-pitched M02 around the same sort of time) has been bubbling away nicely, so I’m not sure what’s up with this starter. If nothing happens I’ll dry-pitch some more yeast on top, but let’s give it a couple of days.
I pinched about a litre of juice from one of the three buckets and threw in a packet of M02 and some dissolved yeast nutrient before placing it on the stir plate for 24 hours at 20℃, then leaving it to settle down and hopefully start fermenting. The idea is that the extra nutrients and increased temperature will cause this yeast to grow more rapidly than if I were to pitch it dry, so that when I do unleash it on whichever bucket I choose it’ll get to work with added vigour. Then again, I’ve lost the time it’s taken to make the starter, and the material used will be the same as that into which it’s pitched, so I’m not sure it’ll show much difference to dry-pitching, which is what I’m doing with Best Wellies. Essentially this is an experiment to see if it’s worth making a cider starter.
I decided that this bucket would be fermented with dry-pitched yeast, so today I threw in a packet of Mangrove Jack’s M02 and kept the temperature as it has been for the past week or so. MJ reckon that M02 is happy between 12 and 28℃ so 15℃ shouldn’t be a problem, and true to form it started bubbling away 24 hours later.
