From: Charles Mcgonegal Date: Mon, 11 Feb 2008 07:51:50 -0600 To answer John H. - concentrates are pretty expensive, and the price for apple concentrate shot up with apple prices this year. They have some conveniences, but price isn't among them. Berry juice concentrates run over $100/gallon. Well over. About filtering, keep mind that pad filters, even the .45 micron grade, won't deliver a sterile product. Pad technology doesn't contol pore size that well. You need a membrane filter to get an absolute pore size - pad filters make good prefilters, and may reduce cell counts enough to get by. And as others have noted, you can still get bitten post-filtration in the bottler or bottle. Sorbate (just under 200ppm) and a little CO2 pressure can go a long way. I've had pad filtered cider in legs keep a year with no problems. Still cider is trickier, and either bumping it up to apple wine, or learning the whole bottle pastuerization technique seem like good ideas to me.

There are a few paragraphs in the book where Jacque talks about some of his daily duties as a young boy. One was helping his father bottle wine for his mothers restaurant. Every day they would go down into the cellar and from the barrels fill only enough bottles for what the restaurant would use that day. After bottling they would burn a sulfur stick attached to a piece of metal that was connected to a bung and plug the whole in the barrel with the "bung burning sulfur stick". This would remove the air from the head space and keep the wine from going bad. My question is wouldn't the fumes from the burning sulfur stick get absorbed into the wine. Jacque didn't say how fast they went through a barrel of wine, but if it took very long at all wouldn't the last few gallons of wine have quite a bit of sulfur in it? If this works, I was thinking that I could keep a few 2 liter PET bottles in the fridge and fill them when needed using the same technique. Thanks, Scott ------------------------------ Subject: Apple rootstocks From: Dick Dunn Date: Sat, 16 Feb 2008 15:06:06 -0700 Jack O Feil wrote, a few digests back, in response to my fussing over difficulty of finding Geneva rootstocks: > I grow apples commercially and there is a nice selection from the Malling > and Bud series.

(You should be able to find info on Geneva rootstocks from some suppliers or certainly with a bit of Googling. See Cummins' web site cumminsnursery.com, or treco.nu, for a couple.) Yes, don't fix it if it ain't broke, but if you're growing where fireblight is a problem, it's way-broke. The Malling (+Merton + LA) rootstocks weren't bred for fireblight resistance, so any resistance they have is I suppose coincidental to a generally healthy rootstock type. The Geneva rootstocks had fireblight resistance as one major goal. - -- Dick Dunn rcd@talisman.com Hygiene, Colorado USA ------------------------------ Subject: Re: Small Scale Yeast Filtering From: Dick Dunn Date: Sat, 16 Feb 2008 15:23:24 -0700 In the last digest, Rich Anderson wrote: > Filtering cider to stabilize it can be a daunting task, particularly if no > SO2 is used.

Rich, are you saying that you only added 50 ppm throughout? (I.e., you tried to use final filtering in order to keep the SO2 way-low?) You advocated pasteurizing, even for dry cider, but is there a reason to pasteurize if the cider was sulfited to more traditional levels. Finally, you said: > Even if you keg it, pasteurization should be a doable thing. On a small scale, how? What I'm thinking is that your argument is for pasteurizing in the final container (so that no contamination can be introduced during a final transfer step). I don't see how you'd manage that--the processing time for a container of 20-60 liter capacity would be so long, it doesn't sound reasonable even if you could figure out how to heat the keg. I can sort of visualize a flash-pasteurizing setup by passing the cider through heated tubing and then into the keg, but that's a bit of a project. - -- Dick Dunn rcd@talisman.com Hygiene, Colorado USA ------------------------------ Subject: Very slow keeved cider From: Claude Jolicoeur Date: Sun, 17 Feb 2008 13:40:15 -0500 I have a batch of cider for which I need a consultation... It was started last fall, by mid october, keeved with PME enzyme. It made a very nice chapeau brun and was racked after 8 days. Original gravity was 1.064. No yeast was added. I guess the keeve was too successful and the juice was low in nutrients to start, as the fermentation is extremely slow. Today, the gravity is 1.051, a drop of 0.013 after 125 days! Temperature in the fermentation room is stable around 48F / 9C since December. If I let it go, probably the fermentation will pick up a little next summer as temperature will rise, but I doubt the gravity will fall much under 1.040, which would leave me with an extremely sweet cider with about 3% alcool. In the past years, my successful keeved ciders had fermented to a gravity of about 1.035 by this date and have stabilised around 1.020 by end of summer for bottling. I have another keeved batch this year which was measured today at 1.035 and is going as expected. So, I am currently evaluating a few different options for my slow batch: 1- Wait and see. 2- Bring it in another room with higher temperature. 3- Blend it with my other keeved batch. The inconvenient of this choice is that the slow batch has a good part of bittersweet apples which the other one doesn't have - I would then dilute the character of this particular cider. 4- Add a tiny bit of yeast nutrient. The problem here would be to figure the quantity. The recommended dosage of the nutrient I have is 5 teaspoons (tsp) per 5 gal batch. This is way too much as I know a single tsp is sufficient to bring a stucked fermentation to dryness. So, if I choose this option, I would probably use about 1/4 tsp per 5 gal. If anyone has comments or suggestions, I would be happy to read you. Thanks, Claude Jolicoeur Quebec. ------------------------------ End of Cider Digest #1438 *************************
