(Around 1500 lb of apples in total.)
- Thanks to Andrew for creative re-purposing of a wood chipper and his hydraulic garage press add-on.
Later improvements such as charging the press with three cheeses at a time and using the hand lever to take up the slack (why didn't we cotton on to this earlier?) meant that pressing time was drastically reduced later on and was less stressful to the cheese cloths.
About 3 good 75 litre tubs from around 660 kg of apples if my math is correct.
A sachet of Lalvin EC-1118 yeast was added to each while filling.
Three days after pulping and the yeast is already starting to do its thing on around 88 gallons of juice. (Proper gallons, not US gallons.)
An additional 3 or 4 pints per day / per barrel is needed to keep them topped up while they blow the solids out the top in this initial stage.
Also Planning on doing a few 5 gallon jars to spread the risk, being the caution s*d that I am.
Pressed another batch of apples to put into glass later on.
The resulting juice was left in two of these 60 litre containers...
...And these two for primary fermentation.
Barrels contents (1005 original gravity and a ph of 3.5) were, in turn, decanted into a sterile 205 litre plastic drum and the sediment rinsed out then 'scrubbed' with a chain on a rope (Top tip from Andrew Hewett) before a 22mm hole was drilled in each for the taps. Incidentally. The oak is about an inch thick and the drill was barely halfway through before the air was filled with the aroma of Jack Daniels.
These holes were tapered by hand with very course emery cloth using a tap as a former. Slow and painful but it did the job. - Blisters are healing nicely!
They were then rinsed repeatedly with a hot water pressure washer before a final rinse with 30 litres of near boiling water. - No steriliser used on the oak barrels!
Barrels were then placed in position, refilled with an an additional 2.5 gallons to each from the 5 gallon plastic fermenter. (1020 o.g)
The additional batch was decanted into five and a half x 23 litre carboys. Not sure how the half will fare with air space but CO2 is active in warmth. Will most likely transfer the half to smaller demijohn flasks at the weekend.
A bit of DIY tech to keep them warm during the seasonal temperature drop.
Two layers of insulation, a thermocouple and a heat pad under each keeps them cosy, efficient and frost proof.
Channel four not currently used and is indicating ambient air temperature of 10 degrees here.
Set temperature has just been reduced from 20 to 17 degrees C.
The secondary CO2 regulator feeds a positive pressure aspirator regulator. (atmospheric +3mbar)
The CO2 bottle will be set off the ground on a sculpted GRP (If I have the time.) wall mount below these.
Gas line runs around the walls where Tees will be added later. - Think twice, cut once!

The tees will accept either blanks or aspirator pegs as required to blanket a barrel's contents when drawing off begins.
There's room on the stand for five barrels in total.
An unexpected diversion...
Small branch down on electric fencing on the south side of wood.

8 minutes later
Now in kit form and in the back of the ATV. - On to the next...
Broken fence stake to be replaced at the western side of the wood.
So-called treated stakes failing early are slowly being replaced by (hopefully) properly treated stakes. from.jacksons fencing
Over the last five years around 450 have been replaced out of an estimated 1200. January or February each year the fence is walked and every single stake is given the wiggle test. - Grab top, push-pull using body weight and feel/listen for weakness... Sometimes quite subtle but you get to know.
One more branch reported on the north side cut up and then.....
in the video below, three additional guests on the left are now keeping the first two company for the duration.
At the rear are the six 5 gallon jars of the last batch. These had 1kg (2.2lb) of demerara cane sugar added on the 10th, mainly to add flavour though will probably add slightly less than 1% to the final alcohol level so likely 6.5 to 7% The cider removed from each to make room for the syrup conveniently topped up the half full glass with a 3 litres of boiled water to finish off and is the one shown in this video.
Around 240 pints worth in glass.
Sugar disolving in boiled water.
Top tip: 1 kg of sugar + 1kg of water = 1.5 liters of syrup.
This is it!
Locks removed. o.g down to 1. Samples drawn with large pipette were crystal clear with very acceptable flavour to both barrels.
- So far at least.
Finally they were each topped up with around 0.75 litre boiled water before bunging and driving home the hard spiles.
Will cover later to keep dust and bird s#*t off these weak points, ready for when aspirator/gas pegs are fitted before drawing cider off.
Ordered an optical refractometer today to do a little science and calculate the final alcohol level of the batches. It'll be interesting to see how good/bad the initial estimates turn out to be. It should also be useful to double-check initial and final original gravity measurements in future.
Still drawing from the first barrel. Excellent feedback from partakers. - Great with a meal.
Checked the five glass a few weeks ago. Two have cleared completely. One of which sampled and is OK. The second untouched so far.
Three other glass cloudy in varying degrees so not hopeful. Primary fermentation last year was very slow due to temperate dropping that month so guessing that didn't help.
