Default Checking for clarity

Hi,

how do people go about checking if their wines are clear? I have a red and
a black cherry that are so dark I can't see through the jars. Any tips
anyone can give?

Cheers

Carrots?

Just kidding. I tried shining a torch through it but not sure what I am
looking for. I can see the torch through the wine but still am not sure if
it is classed as clear or not. I am pretty new to this.

A bright light on the opposite side of the carboy is useful. Also siphon a
bit off and put it in a glass remembering that the wine is generally clearer
at the top.

on the opposite side? Shining a light in my face just makes me blind :-)

I put my bright, 'spotlight' beam of light perpendicular to where I'm
looking, and move the beam slowly from top to bottom of the carboy. If I
can see the light beam in the wine, then it's got some cloudiness.

Now for the 'more than you ever wanted to know' explanation...
Turbidity is the technical term for the clarity or lack thereof in a
liquid. And it is measured as the ratio of intensity of the light
scattered perpendicular to the beam divided by the intensity of the
light which passed through the liquid from the light source to the side
opposite of the beam (i.e. on-axis).

I use a laser pointer ($2.99) to check for clarity. I have never seen a
transparent wine that was so dark you couldn't see through it. Cloudy yes,
dark, no.

Years ago, when I used a torch, I would look to see if the wine allowed
me to clearly distinguish the wire filament in the bulb. The wine may not
transmit a lot of light due to its darkness, but if it is clear you should
be able to see the filament w/o any haze around it. The degree of fuzziness
will tell you how much clarifying still is needed.

A laser is perfect for this. Mine was 2.99 and worth $50....

OK,

I got around to doing this. Shining through the red wine from right to left
I can see the beam crossing the wine. If I shine towards myself I can see
the light but it is hazy.

The black cherry is a different story. Shining across I see nothing.
Amazingly though, the wine is so dark that shining towards me I also see no
light coming through at all!

Your cherry seems to be a marvelous light absorber.

Try shine it along a thinner path through the wine... instead of across
the diameter?

If that doesn't work, guess you'll just have to get a much brighter
light. Any halogen spotligtht available? Bright white LED? Laser?

You definitely need to wait a while longer.

You =should= be able to see the glowing filament of the bulb in the
torch. You probably still have some suspended materials.

I guess I will wait a bit longer then. Weird though, the cherry is really
dark right to the top and has been standing for about 8 weeks. Hang on a
minute.....



.....runs upstairs.....



.....just checked again. At the neck it is a VERY dark red. If I switch the
lights off I can just see the filament through the width of the demijohn.
Seems reasonably uniform top to bottom with it being just a little less
visible (the torch) near the bottom of the demijohn.
