All Halocha Shailos and Tiffeh Questions

[Chaikel]

From an amatuer vinter and wine making buff I know:

[Yeast] grows naturally on the outside of the grape. Most people add their own yeast because it isn't possible to know if the natural yeast is bad until it ruins your wine

What percentage of wine sold in stores have yeast added?
Probably all. It's how they keep the flavor consistent
They usually kill the natural ones and make their own

[Work-for-ur-muny]

All wine is fermented with sugar and yeast

Then maybe we should make mezonos on wine like his zeideh makes shehakol on grape juice...?

Besides for the fact that it cant ferment naturally anymore there is another problem that it isnt considered choshuv after the fermenting process so that also can take away the bracha of hagofen

You can say that about mevushal wine as well.

as far as i remember my dad only uses not mevushel

[yochiek93]

Right , Just the Oleh

the oleh doesnt say it because he still didnt say the second bracha

That's for a different reason, not because of any question regarding the brocha.

[username]

That's what I remember being taught.

My turn - When should the Ba'al Koreh say Chazak Chazak and when should the Oleh say it?

In shu,a, its mivuar that the tzibur says chazak TO the oleh that finishes. Sort of like shkoyach. In hilchos simchas torah. Lifi zeh, the oleh does not say chazak.

From the Hayom Yom of 23 Tishrei (Simchas Torah):

אין קוראים בתורה בלילה. נ"כ [נשיאת כפים] בשחרית. אין נוהגים לפרוש טלית על ראשי העולים לחתן תורה או לחתן בראשית. גם העולה לתורה אומר חזק חו"נ

1 grape juice CAN ferment naturally ,   2 fermenting means turning into wine... that is chashuv !

     Just wondering, can we compare the ability for juice to ferment naturally, to when it needs human intervention to make it ferment?

     I know many people who, although they use grape juice for kiddush all year, are makpid to use wine, or home-squeezed grapes for the 4 cups on Pesach because of this fermenting reason/problem. I also personally know a well renowned and respected rav/rabbi who is makpid to use for the 4 kosos only wine not containing sulfites. Though, I'm not quite sure why, and whether it has to do with the fermenting issue.

4 cups of wine are Rabbinic . the friday night cup may be Torah Obligated (see biur halacha) there is zero reason to be stricter on the laws of wine by the seder night. The reason the respected rav does not use sulfites or store bought wine is because of pesach stringecies.

Zero?
For Seder night derech cheirus is required according to some poskim. They hold alcohol content is required.

You need yayin hamesameach for the 4 cups; which is not required for kiddush on Shabbos.

I once met someone in the Walmart buying great value grape juice.  He told me בשם a not well known or respected פוסק (I don't remember whom) that they take grapes and put it in the machine and then the humans don't touch it again until it is pasteurized which makes it mevushal and therefore you can buy any commercial grape juice.
I found it interesting and was actually wondering what the flaw in his argument is.

Weirdo.

     When you have a bottle of (not mevushal) grape juice laying around in your refrigerator and your non-Jewish cleaning lady moves it from one side to another, isn't that considered touched? So what does it help in this case when it is touched through a machine. I know that Kedem only has Jewish truck drivers, although the drivers never get anywhere near touching any of the contents in their tanker vehicles.

how does he guarantee that the pasteurizer is kosher? It could have been used for many things like clam or meat soups etc.

That's yet another problem that exists with this GJ; which is besides for the yayin nesech shailah.
