After finishing up with the cyser I just did a check on the currant mead.
Oe: 26 (OK)
pH 3.45 (Uh, somewhat lower than I wanted)
The color is great – bright red – and not pink that I was initially afraid of since the amount of juice was quite limited. It has also cleared quite well already.
I need to lift pH a bit which I will do with potassium carbonate. I just need to test how much to add.
Finally I covered the mead with a layer of CO2 (See “CO2 generator” under Knowledge Tools), sealed the lid, and attached the airlock.
