A Spiced Apple Cider, Twelve Percent by Faith
Trader Joe's pressed cider, 500 grams of sugar, and a quarter teaspoon of yeast that has no business being this optimistic.
The plan started, as most of my plans do, with a $4 jug of Trader Joe's Spiced Apple Cider and a thought that should not have been allowed to leave the car. The cider is good — quietly spiced, cinnamon and clove and a little star anise in the background — and it is not, in any meaningful sense, a wine base. But it is cheap, it is filtered, and the label is short, which are the only three qualities a 1-gallon experiment needs.
I poured the gallon into a clean carboy, added 500 grams of plain white sugar, and shook until my arms hurt. The hydrometer settled right around 1.110, which is a number that, by the rule of thumb, will end at roughly 12% alcohol if the yeast actually does its job. That is a lot of alcohol for a gallon of juice that cost less than the hydrometer. I told myself that this was the point.
The yeast is Lalvin 71B — a fruit-wine strain that ferments clean, eats sugar like it owes it money, and tolerates alcohol up to about 14% before it gives up and goes to bed. A quarter teaspoon is the pitch rate I have used before on a 1-gallon batch with this yeast, and it has worked, which is just barely enough evidence to keep using it. I rehydrated the yeast in a little warm water with a pinch of sugar, gave it ten minutes to wake up, and pitched it in. The carboy got an airlock, a rubber stopper, and a towel over the top, because I do not yet trust myself to do this part cleanly.
Twelve hours later, the airlock started to tick. That is the sound a healthy fermentation makes, and I have learned not to celebrate it until day three.
Three weeks is a tight schedule for a 12% cider, and I am not pretending otherwise. Most of the 71B ferments I have read about finish closer to four weeks, and the higher the starting sugar, the harder the yeast has to work to get all the way down. The plan is to leave it alone, take a hydrometer reading at the two-week mark, and decide then whether the gravity has stopped moving. If it is still dropping, I wait. If it stalls, I have a second packet of 71B in the fridge as a restart, and a fallback plan to back-sweeten with the last half-cup of unfermented cider if the final number is too dry for the table.
The success condition, as far as I am willing to define it on day one, is simple: a clear, dry, gently spiced cider that lands somewhere between 11 and 13 percent and does not taste like a chemistry experiment. Anything past that is a bonus. The failure condition, equally simple, is a stuck fermentation at 8% that I talk myself into bottling anyway. I have done that one before. Three weeks from now, we will see which one shows up.
