Re: processing grapes

I don't have a press, and didn't know how else to go at the grapes.

Not sure what a victorio strainer is, but I'm assuming it is some sort of food processor.


I hope you destemmed the grapes first! Otherwise the wine will be very tannic and bitter, and take quite a bit of aging before it will be drinkable.


You can speed up the destemming process by scraping them across a milk crate, or 1" chicken wire (poultry netting) mounted in some sort of frame --- with either suspended over the primary. That takes about 1/3 the time of pulling them off the clusters one by one.


The problem with a juicer, food processor, or "all-purpose fruit crusher", is that we don't want to break open the seeds, or the wine will be very bitter. According to a recent post (I think it was Clyde's), for white wines, we don't want to macerate the skins either, as this will release certain undesireables, just as if we fermented "on the skins".


An electric or crank-operated grape crusher does a very quick job, but the least expensive ones cost about $200. If you can't buy or borrow one, or you are only dealing with a few grapes, put the grapes in a 5-gallon white plastic paint bucket (sold at Walmart and Home Depot for about $2, or at your local home brew for $10), and pound them gently, butter-churn style with a 4x4 post. Since the grapes tend to float as the liquid is squeezed out of them, making the task more difficult (hard to crush a floating object), pick up a few $1 nylon "paint strainers" at Walmart or Home Depot (or a more expensive "press" bag" at YLHB), load them with grapes, put them in the bucket, and pound them with 4x4. Then, when this batch is crushed, pour off the juice, empty the bags into another bucket (if you are fermenting on the skins), and continue with another 5-gallons of grapes. It goes pretty quickly.


It's best to crush outdoors, as there will always be a bit of a mess.


Or should I have just stomped or mashed the grapes with feet or masher?

Stomping grapes by foot is romantic, but not very efficient. And talk about messy.....


A 4x4 works much better then a masher --- unless you are doing a very small quantity.


There's also a lot of really fine suspension in the wine....
> So I hope this was all worth it, it looks like a greenish brown stew...

This is normal. The colour of the must will initially be greenish brown, and not very appetizing. Within a few days it will be a dark red.


i just pitched the yeast tonight, so we'll see how it goes for the next

couple of days.


Be sure and punch down the cap (or stir the must ) twice daily, so the cap doesn't dry out. This will aid extraction (of colour and flavour), and reduce the chance of baceterial infection. And keep it covered!

Are these Niagara grapes or grapes from Niagara?

Anyways, sounds like you had a ton of fun :) If they are niagara grapes (a white variety) you'll want to get your juice into a fridge or if cold outside now at night where you are, you can put it outside and that well help settle out some of the sediment and gunk you mentioned. Hope all goes well, update us on the progress.

Rick - Next time you process grapes, if you still do not have a grape crusher, I recommend that you do crush the grapes by foot. For years, before we bought a grape crusher, my wife crushed all of our grapes by foot. For several hundred pounds of grapes it only takes a couple of hours. It results in a lot of juice and no broken seeds. I've taken her place several times and you can easily feel uncrushed grapes with your toes so it's easy to crush essentially all of the grapes. Use a five gallon bucket...it keeps the grapes close to your feet. Dip out juice and crushed grapes as needed. It's a rather pleasant thing to do on a nice late summer day.

I sat in a lecture once where Dr. Christian Butzke told us that an enzyme was isolated from toe jam that aided in color extraction. Never new whether he was serious about it or not!?

I put my grapes into a plastic 5-gallon pail, filling it only about 1/3 of the way up. I then wrap a plastic bag around one end of a four-foot piece of

4" x 4" wood and pound them until they're all crushed.

If I'm making red wine, I pour it all into the primary vat. For white, I have a press. Lacking a press, I'm sure the squashed grapes would work well in a food processor, juicer or just hang them in a nylon bag and let the juice run out.

Clyde - I always knew there was a good reason to crush by foot. The best wine I ever made was my 1999 Vidal (grapes crushed by foot by my wife). I think I'll chuck the grape crusher and have her go back to stomping grapes next fall.

great responses and replies! Thanks for all your input. These are Niagara grapes, the cousin to concord grapes. Welches uses them to make white grape juice.

Destemming by hand was VERY time consuming, but now it's fermenting, having pitched it with cotes des blanc yeast. I chaptalized it, added sugar until it was about 13-14% p.a.v. the cap is pushing to the top and is made of all that very small and fine sediment. I will probably scoop it off soon. It's somewhat clear underneath. I think most of it will drop out afterwards. Next time I think I will just pick off the bad grapes and crush by foot (hopefully no toe jam!) or a 4x4. Im thinking of building a crusher....maybe a good winter project!

Thanks again! Rick

As the fermentation draws to a close, I've been skimming off all this brown gunk and sludge that has been floating to the top, and as I do, I'm seeing a very nice clear yellow juice underneath... and a magnificent niagara aroma.... So, experience is a good teacher! Though the processing was a bugger, the end product is going to be wonderful, almost 6 gallons of it!

Take care, Rick
