Red Wine

[REDWOOD]

I have quite a few bunches of black grapes that I usually leave to the birds but this year has been exceptional so I have been thinking to take a few to make some red wine but how many do I need to make 5 litres of wine.
I have also thought about using a centrifugal juicing machine I have ?

Try some through your juicer.
See what yield you get.

If you get 2/3 juice 1/3 pulp by weight (for example) then you are going to need 7.5kg grapes for 5kg (roughly 5 litres) of juice.

Juice would be about 1050 density, so 5 litres would actually be about 5% less than 5 litres.

But your big unknown is the extraction efficiency of your juicer …

// You need the skins to make *red* wine, IIRC …

 

[REDWOOD]

Thanks for that
It's a very good juice extractor, the pulp comes out almost dry
I have more than enough grapes, I'll let you know how many kg's I had to extract

 

[REDWOOD]

Why do you need the skins ?

 

[protheroe]

to make the wine red. if you just use the juice it will be white wine

 

[REDWOOD]

That's fine, I don't drink lol white wine it is then.

so 5 litres would actually be about 5% less than 5 litres.-

Please explain how. That is a new one for me!!! Oh, and we don't measure density, we use Specific Gravity. An all too subtle difference for some.

Glad you were able to follow despite my silly typo!
And "1050 density" and such comes from long enough messing around with Marcy buckets …

I wonder glass bottle of Cabernet Sauvignon old about 26 years, not some special conditions stored ( just "dark place"). Is it rotten or good for opening?

Only one way to find out

 

[Goran]

Absolutelly right. Every year remember of it and think when to open it, and years pass so quick and it survives..

Most wines mature best in the cask and slowly for a few years after they are bottled ... but every wine reaches a point of perfection depending upon a huge number of factors after which point it no longer gets better, it stays the same for a period of time then... it gets worse.

Every wine ... indeed, every vintage is different.

However, I'd drink it and find out ... what are you waiting for ?

 

[Goran]

Always wanted for some occasion when family together, but at the end some other wines bump in, or completelly forgot it. Or what happen in the most cases in such high speed living can't get all of us together..
Interesting link, thanks.
Prognosis at that link is good: " out-live almost all other wines".

I'm confused. Could you explain please. I have just read that its is a ratio of densities. Is that why specific gravity is not considered a measurement?

Surely we can measure density in g/cm3 ( but this would be far less accurate if you are not going to use large volumes to do the calculation, which is not practical for home brew)

Just asking, I'm not looking for an argument.

Joined the wrong forum then haven't you?

Gotta be unique in any forum ... arguing about SPECIFIC GRAVITY ? What is the world coming to ? And on a beekeeping forum !!

If only we knew what gravity was

 

[pargyle]

If only we knew what gravity was

Gravity is a contributing factor in nearly 73 percent of all accidents involving falling objects.

 

[REDWOOD]

And keeps us with our two feet firmly on the grown, except a few who are filled with hot air

Can't you be more specific? (Without bringing in General Relativity?)
