Biting and bitter cold

25 Feb 2018 – General

The temperature over the next few days looks to be -10°C and lower.

We are taking advantage of this to facilitate tartaric stabilisation. Tartaric acid tends to form supersaturated solutions – which means that it should precipitate crystals (Weinstein), but thus far has not!

With a proper reduction in temperature this becomes easier.
