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.
Footnote: the bit of water standing on the bung has already frozen, and shows the logo of Tonnellerie Berthomieu in relief.
There are no photos with those IDs or post 3723 does not have any attached images!
