Bottling Cider



With outdoor temperatures below 20F and a raw wind blowing was a good time to bottle cider in the kitchen, by the warm stove. I had two six-gallon pails of pear and apple ciders that began fermenting last September. By December their fermentation locks no longer bubbled: yeast had transformed juice sugars to alcohol and carbon dioxide (the bubbles). As long as air (oxygen) does not contact brewed liquids (by keeping the air lock filled with water), one can keep it for months and bottle it a month before running out of finished ciders. It takes four to six weeks for yeast to carbonate cider in bottles.

I had accumulated about 10 gallons worth of empty bottles so I began processing the first two cider vessels: 6+ gallons of "hot" apple cider and 6 gallons of pear cider. By not moving the tall pails while carefully removing tops, I was able to ladle off three gallons of clear cider from both without filtering. I added 12 ounces of maple syrup (for the yeast to transform into carbonation) to each three gallon lot and filled 26 sixteen ounce flip-top bottles of each type. I decanted the remaining liquids through cloth filters, reserving the pear cider but filling another 25 bottles with the hot pepper apple cider. 

Last September: I had placed 100 pureed jalapeƱo peppers, including seeds, in a cloth bag and boiled in cider for 20 minutes. I then added this clear, red tea to the brew to heat up this apple cider. At this point it tastes a bit too hot but time and mellowing while fermenting to create carbonation should make this an exciting beverage.

The second half of the pear cider will go to friends who have a relative who is fond of this beverage.

Bottling Hard Cider

I finally got around to bottling last year's cider that has been resting in the basement for almost a year. To five gallons, I added 24 ounces of maple syrup before bottling it in 40 flip-top bottles. The most significant work involved washing and sterilizing the glass, removing and scrubbing the rubber washers and then reinstalling them. These bottles have been in storage for years, having come across them, empty, at a large event that featured European beers.

In a few weeks, it'll be time to pasteurize them so they maintain a bit of sweetness and don't explode from too much carbonation. The 6.5 gallon brewing bucket is now ready for this year's second batch.

Processing Apples

Anticipating the largest apple harvest in over a decade, I modified an exercise bicycle so that I can grind up apples by pedaling with my feet, while cutting up the apples by hand and removing bad parts. We pick apples for eating and those used for pies and baked goods, but it takes too long to pick the dozens of bushels ripening this year. We need a way to squeeze the juice out of apples we pick off the ground that's quick and easy. Adding a second shaft to the exercise bike makes it easy to change the gear ratio between the pedals and the drum that grinds fruit. If it's easy to do, make the drum turn faster than you pedal. If it's difficult, gear it down.

The drum I chose came from an auction many years ago and is welded to a shaft, all stainless steel. The drum has grooves that quickly grind up apples but then fill up and require lots of hand work to continue working. I tried different thickness plates for the drum to mash apples against, but all three didn't change throughput. They all took a lot of work to enable it to continue mashing apples.

Once you have many pails filled with ground up apples, there is the task of separating the juice from the rest. I built a conventional slat-lined cylinder that I hoped would let liquid quickly flow down to a tray that emptied into a bucket. I used a 12 ton hydraulic press to push on a tightly fitted piston. The first quart came out very quickly but then slowed way down until almost nothing more came out. Even with many additional tons of pressure on the top, very little cider came out the open strips between the slats. With over 5 gallons of mash in the cylinder, less than a gallon seeped out in 14 hours, periodically pumping the hydraulic ram. It seems that the volumes of pulp near the openings between the slats quickly drained away and blocked liquid from the interior from getting through.

 I searched Craig's List for options and found an ancient grape crusher for $50 available two hours away. I brought it home, disassembled and cleaned it, but decided it would take a few days to both connect it for pedal power and also modify it. The two drums that rotate at different speeds are open at each end and were filled with dried grape stems, seeds and skins. These need to be sealed so they can be readily cleaned without disassembly.

My goals for the weekend were to start five-gallons of apple cider fermenting and to make a large batch of apple sauce. The quickest way to do both is to use a squeezer that separates pulp from skins, stems and cores.

To remove the apple bits from the juice I made five platens that had hollow cores and tops with lots of holes that allowed juice to flow unimpeded. A gallon of apple pulp was loaded into a frame lined with a piece of cloth ten times the size of the platen. After folding over all sides of the cloth, the frame was removed and another platen placed on top and the process repeated. Once the five sandwiches of platens and wrapped apple pumice were complete, it took only ten minutes of pushing slightly on the hydraulic press to turn the layers of apple to moist fruit leather. It took two pressings using five 5-gallon pails of apples to make five gallons of cider.

When All Layers are Complete, A Solid Plate Is Placed on Top and the Stack Compressed by the Hydraulic Cylinder. The Juice Flows Into the White Tray on the Bottom and Drains out a Hole into a Bucket on the Ground.
I had to process about eight more gallons of apples to make enough juice to make three gallons of moist fruit leather into proper consistency apple sauce. Cleanup took only a few minutes to rinse the metal parts in water. The cloths were folded, placed in a plastic bag and frozen until next batch. After adding some sugar and cinnamon, the processed apples made 30 pint jars of applesauce.
