Cider year 10: 232 gallons in a day

November 2, 2014

Last weekend marked the 10th successive year when Alexis and I have made cider with Holly, Becky, and a steadily growing crew of enthusiastic friends.  I am amazed by how this tradition has taken root, and how ever-increasing quantities of cider are produced and just as rapidly disappear.  Below you will find the annual report; thanks to everyone who sent photos; please send more if you have them, and I’ll link to other peoples’ blog posts if they make them.

Late in the week the weather was cranky, so I borrowed a friend’s box trailer, which was very handy for hauling the large number of cardboard boxes of glass bottles and open tubs of miscellany which always accumulate before cider. Between that and two bins of apples I was heavily laden for the trip to Five Islands.

Pedal-Powered Cider in Cascadia

October 22, 2014

A fellow named Steve Haeseker in Vancouver WA sent me a note mentioning his very cool experiments with pedal cider equipment, and sending a link to his video:

The craftsmanship looks really nice. They use a small wood chipper coupled to a bike to grind the apples, and a pedal-hydraulic press made from a log splitter to do the pressing.  Then they feed the pomace to some cows.  The chipper is a neat idea, though the grind looks a little coarse (similar to our first-year results with the antique cast iron press).  I bet it could be modified to make a finer grind by grinding down the cutters and then tightening up the gap. But, given that a lot of apple grinding equipment (including ours) isn’t self-feeding, he may be on to something with the wood chipper concept, and I can see how fabricating a flat disk and mounting cutters to it could be a lot simpler than the multi-step machining process we used to make our cutter drum.

The press is made out of thick hard maple recovered from a bowling alley – major style points for that.  Unlike our press, they count on the wooden uprights to take the full tension of the press; it looks like they use a smaller cylinder (maybe 2.5″?) so the load will be less, but they still get good pressure by using a smaller cheese.  In watching the video it’s not clear why they need their cheese frame, since they aren’t really packing the cheeses full.  We have some instability in our cheeses that sometimes requires re-stacking the press; I wonder if we could do better by cutting the cheese frame down to 3″ from 3.5″ thick.  Alternatively we could make some shims that enforce a certain minimum cheese thickness until the stack is down to ~1/2 thickness; by that point the viscosity of the pulp will be much higher, and I’d think the stack would be less squirrelly.

Anyway, hats off to Steve for joining the ranks of pedal-cider enthusiasts!

5IO process for pitching yeast on cider

December 23, 2013

Reuben asked in a comment about how I pitch yeast, and since the process has never failed us I thought I’d make a post of it.

Usually I add 1/2tsp of potassium metabisulfite to each 5-7 gal carboy the morning after we press (I think sometimes I do it in the evening).  This year we actually added it to the carboys ahead of time, so the rush of cider from the bulk tank did a good job of mixing it in.  That starts the clock, and I aim to pitch between 24 and 36 hours after sulfiting.  I am not at all an expert on sulfite, and would appreciate a link to detailed info on what the chemistry is, how long it is active, etc.  We lug the jugs down to the root cellar (which is probably in the fifties or low sixties that time of year) and that’s where they stay.

Anyway, our goal is usually to pitch on 5-6 carboys.  I mix a half-gallon of sugar solution with 5-7% potential alcohol in a stainless pot.  I used to use dextrose, but then I ran out, so I’ve been using plain cane sugar ever since.  I throw in a few crumbs of nutrient, probably around 1/4 tsp. (I’m also not an expert on yeast nutrient, but again, I stick with what’s worked.)  I let it boil briefly, then cover and let it cool.  Meanwhile I’ve sanitized a 1 gallon glass jug and a funnel, and when the sugar water is lukewarm I pour it in the jug and pitch 1 packet of Red Star Pasteur Champagne yeast (the packet is yellow, not red).  I shake it gently to dissolve, then let it sit until it starts ticking (in a few hours).  Meanwhile, I bring a quart or more of cider to a simmering boil, cool it covered, and when cool I add it to the (already working) gallon jug of starter.  My theory is that this gets the yeast accustomed to the acid environment and characteristics of the cider before it is set loose at much lower concentration in the carboys, but again I don’t really know what I’m doing, other than that it works.

At that point I usually have to go back to work, and my mom pitches the yeast sometime on Monday or Tuesday.  She uses a sharpie to divide the liquid contents of the jug into roughly equal volumes, pours a measure into each carboy, and recaps with an airlock.  That’s all there is to it – we’ve never taken pains to keep the carboys at a certain temperature, to aerate, or any other tricks.  I think this will basically always work as long as the starter is actively working when you dump it in the carboy.

Cider year nine – roundup

October 26, 2013

After nine years, thanks to the accumulated contributions of ideas, time, and equipment-building effort, and especially to the wonderfully useful and flexible barn that my folks built, the cider operation is getting to where it runs in a well-worn groove.  And it’s a good thing, since the great majority of my attention has been devoted to Pika Energy, and building affordable, high-quality home wind turbines.  

truckload of apples

Two weeks ago I visited Autumn Hills Orchard in Groton, MA, and picked up two 600lb  bins of mixed cider apples – Kendall, Spencer, and Cox Orange among them.  The owner, Ann Harris, also kindly let me do some sanitation and gather a few hundred pounds of RI Greening drops, so the truck was quite heavily loaded down with apples for the ride home.  The going rate for cider apples this year is apparently $50/bin – illustrating the importance of top-quality fruit and value-added products to the economics of small orchard operations.  That same weekend I also needed to build and test a new wind turbine tower, as well as moving some cidering equipment up to Five Islands, so by the time I was fully loaded with dogs and bikes etc., the rig looked like some kind of Tom Joad/Johnny Appleseed chimera:

The tower test was successful, and my folks and I unloaded the bins using a four-fall block-and-tackle that my dad inherited from a local gentleman, Don Spurr.  Don lives on in our memories every time one of his carefully-maintained tools proves to be just the ticket for solving some mechanical challenge:

The following Wednesday afternoon, Dave, Alexis, and I made the annual pilgrimage to Poverty Lane Orchard/Farnum Hill for cider apples.  I called ahead a couple of weeks, but for the first time in several years, we were disappointed that they couldn’t sell us a bin of bittersweets – they were too booked up with demand for cider fruit from as far away as Michigan and Oregon.  Brenda made it up to us by giving us a nice discount on the ~700lb or so of mixed cider fruit we collected.  We hauled the load with Alexis’ little Suzuki wagon, and it really drank the gas on the way home, but still burned far less than it would have taken to drive the big red monster all the way to the other side of NH.  When we got home, Fern got right into the action:

I managed to get up to Five Islands by mid-day on Friday, and on the way up I picked up the only big innovation in on the equipment front this year.  I bought a 100 gallon HDPE bulk tank from US Plastics, together with a hand-operated diaphragm pump rated for 15gpm.  Together, these made a huge difference in the management of finished cider during the big event.  Dave whipped up a wooden stand for the metal stand that I bought to go with the tank, so we could gravity feed into bottles and carboys.  Working the pump was a big hit with the kids:

Compared to commercial operations, we keep a very high standard for fruit quality going into the grinder; since we have plenty of labor and it’s a sociable activity, each apple is washed and inspected by hand, and any brown spots or other flaws are cut out.  But washing has always been an afterthought from a process standpoint, and in past years (especially when it’s cold) the washing itself hasn’t always been super-pleasant.  This year I grabbed some plastic bristle brushes at the Despot, and Holly and Ben whipped up a much more ergonomic washing station using an old washtub my dad found at the Georgetown Mall:

We started the festivities Friday evening with pot-luck Mexican at the shore cabin, followed by a black-powder demonstration (no bullets) by Jake, and revival of an old tradition, Viking Funeral Ships – in which small barges made of wood planks piled high with birch bark, pinecones, and kindling are set afloat after dark, and rocks are thrown from on shore at a sporting distance to smash them – if anybody has a photo of this, I’d love to post it.  

Breakfast Saturday was amazing as usual, with with Kelsey and Beth’s breakfast burritos and assorted pastry.  Cidering got fired up between 9 and 10AM, and continued on with a brief intermission for lunch, which was headlined by my folks with ‘Nebraska Cream Can Dinner’, a tradition they picked up out west.  As usual, we also fired up the bottling operation, kegging, carbonating, and bottling about 5 kegs worth of cider (minus ‘operational losses’ in the bottling step).  Here Tony and Rita prepare Cornelius kegs for transfer:

Holly, Becky, and Heli took the lead on dinner, producing soups and amazing fresh baguettes. Here’s Holly working the dough:

Dinner for 30-40 people was served in the barn this year, followed by Holly’s usual transcendent apple pies.  MomJones couldn’t make it to cider this year, but she sent us four large folding tables that made for a very convivial setup.  All told we produced approximately 207 gallons of cider, per the tally sheet, with an estimated yield of 69-70%:

Thanks again to everyone who participated this year. Next year is the 10th anniversary – I don’t know what we’re going to do, but it’s going to be big!

 

 

Pedal cider press does off-season duty as a broach

June 21, 2013

I’ve needed a hydraulic press on a couple of occasions recently, and haven’t felt like buying one of those clanky steel-frame jobs with a bottle jack – so on the last trip to Five Islands I brought back the cider press and bike-hydraulic setup, and we’ve been using it in the woodshed as a 20-ton press.  While it doesn’t have the adjustability of the steel presses, it does have a 24″ stroke, which goes a long way.  Here we have just finished broaching a Lovejoy coupling to accept a key:

press used as broach

 

I have a notion to upgrade the pedal-hydraulic power unit to make it less janky and more portable, making it better suited to other applications, such as operating a worm-drive winch to raise and lower wind turbine towers.  But in the meanwhile we might as well keep it well exercised…

Jari Mower RIP

June 16, 2013

jari on fire

I am sad to report that the Jari mower bit the dust this weekend.  I purchased it about two years ago from a guy upcountry, and put several hours into getting it running well.  I sorted out most of the issues, including the frozen-up cutter bar and rotted gas tank, but the replacement tank never quite fit right – there was a slight intermittent gas leak between the top of the tank and the carb, and I never could figure out why.  However, on Saturday it finally caught up with me.  The mower ran out of gas so I shut it off, filled the tank, and as soon as I cranked it up a small flame started on the surface of the carburetor. I tried to bat it out with a mat of fresh-cut green grass, and it almost worked, but the flames persisted.  I ran over to the neighbor’s and grabbed two fire extinguishers, and exhausted them on it, but by that time the metal was hot enough that it re-ignited after the powder stopped flowing.

I didn’t think it would explode, since the gas seemed to be escaping from the tank – at first through the leak, and subsequently through the zinc carburetor, which melted into a puddle on the ground.  Still, I ran down the hill for some hoses, to tap the neighbor’s water.  At peak the flames reached 6-8 feet high, but by the time we had the hoses up there the gas had burned itself out, and the fire was reduced to burning the rubber tire, belts, and the thermoformed plastic fairing on the front.  Ben Wilkins tossed a couple of pails of water on the smoldering heap and the excitement was over.

Once it cooled off, Bodhi and Kieran rolled the machine down the hill and I took stock of the damage.  The engine was pretty well baked (as I mentioned the carb had completely melted), the left tire and shroud were shot, and the belts were burned down to the fiber cores.  But the frame was intact, and even most of the paint was still in good shape – I tipped the machine over on its side when it caught fire so the tank was up, and there wasn’t much to burn up forward.  One of the idler pulleys looks pretty baked, so it would probably need to be replaced.  Joshua and I toyed with the idea of doing an electric retrofit, since sickle mowers don’t use a lot of power compared to rotary machines, and using two separate motors would significantly simplify the mechanicals.  Unfortunately, I haven’t got time to do a major rebuild (or an electric conversion), so today I bought another used sickle mower (Troy-Bilt make) from a nice retired couple in Cornish – I’ll tune it up next weekend and see how I like it.

Cider Weekend, year 8: in the big barn

October 22, 2012

Thanks to everyone who pitched in to make the 8th annual Cider Weekend run remarkably smoothly. The weather was downright damp on Friday and Friday night, so my folks dragged the cider equipment into the big new barn they’ve been building, while I made the annual run to Poverty Lane. Work prevented me from making the usual improvements to the pedal-powered equipment; I barely had time to assemble everything and make sure it still ran. Joshua and Kelsey got things kicked off right on Saturday AM with delicious breakfast burritos and chocolate pastries, and then we set to work.  We set up a nice little process flow, with washing, grinding, pressing, and bottling running counter-clockwise in the first two bays of the barn. We pressed sweet cider first, then the bin of Yarlington Mill I brought back from Lebanon. Thanks to Brenda, Steve, and the crew at Poverty Lane for finding us a bin of bittersweet despite the weird spring weather.

MomJones made a big pot of mac and cheese for lunch, which was washed down with copious quantities of cider.  More and more folks kept arriving, and taking turns at each station, and the jugs filled quickly. We bottled four kegs of 2011 cider in parallel with the pressing, using the dual counterpressure rig. We were cleaning up by 4PM, and the total production was approximately 200 gallons, with approximately 73% yield (plus however much went straight into peoples’ mugs right off the press).  Holly led an epic production of wood-fired pizza and delicious apple pie for Saturday dinner at #70, and Jake ran an extended tomahawk training session and contest, which was won promptly by Narath, who carried off the prize, a brand new ‘hawk hot from the forge. The kids got their turn at the tomahawks, and when the crowd thinned out a bit we played some old time music.

Sunday morning saw apple pancakes at #5, then more cleanup and some folks paddled around in Robinhood Cove.  Heli made a nice lentil soup to go with leftover pizza for lunch, and folks departed laden with cider. I sulfited the newly filled carboys, transferred them to the root cellar, and made a starter for Emily to pitch the following evening.

Thanks again to my folks, grandparents, and Joanna and Jake for hosting, to the folks who made all the delicious food, and to everyone who pitched in to make this year’s Cider Weekend the biggest yet.

Open Source Ecology

September 29, 2012

A day or two ago I heard a piece on NPR about a guy named Marcin Jakubowski who is on a mission to design and build the Global Village Construction Set, “a modular, DIY, low-cost, high-performance platform that allows for the easy fabrication of the 50 different Industrial Machines that it takes to build a small, sustainable civilization with modern comforts.”   As described in a short TED talk, Jakubowski explains that he was a theoretical physics student, started farming when he felt that he lacked practical skills, and had bad experiences with old farm equipment that motivated him to design simple, practical open-source tools. This evening I checked out the website of his organization, opensourceecology.org,  which has a work-in-progress wiki-based compendium of concepts, specifications, designs, fabrication videos, and test images.  The group is big on modularity, hydraulics, and structural steel, and they’ve done a pretty impressive amount of development on a few of their concepts, including a skid-steer tractor and an automated press for making rammed-earth blocks. They are based at Factor e Farm in Missouri, which reminds me a lot of stuff I’ve read about the New Alchemy Institute.
