A cyser replaces the water with apple juice, giving a drink that is both sweeter and tarter than a plain mead. Twelve pounds of honey across five gallons — under the usual three-per-gallon, because the juice brings sugar of its own. Barrel-aged six months.
Makes. 5 gallons
Vessel. Open-top bucket, about 6.5 gallonsThe vessels hold about 6.5 gallons to the top and only ever get 5 gallons of brew, so there is an air gap above it. That gap is what stops a blowout.
Yeast. A packet of whatever brewer's yeast you fancy. Champagne yeast is the one used here, because it keeps going to around 15% — and your local homebrew store will happily point you at the right one for what you are making.
Scaling. All of these scale down. A single gallon bottle of fresh apple juice with some of it swapped out for honey will get you a small batch, no special kit required.
Six months in a 5 gallon barrel, level 3 char, and it tasted great. Old whiskey barrel or new, either is fine — his words on both the size and the char were "or whatever, it doesn't matter".
Fermentation produces carbon dioxide, and a sealed or blocked vessel is a pressure vessel — the Valentine's Brew blocked its own blow-off tube. These worked for the brewer, which is not the same as working with a different vessel, yeast and kitchen.
