I’m not certain of the yeast name used to do this. I told a wine making shop what my direction was and he handed me the yeast and said be patient because it takes a while to get it started. And it took about three days after adding the yeast for it to fire up, but did so in a big way when it got going.
I spoke with a fairly accomplished wine maker who mentioned his adventures into the cranberry wine. He said he’d tried adjusting ph and acidity levels and messed up a 20 gallon batch in doing so. His suggestion was to do small batches. He mentioned that cranberries are at the mercy of the weather while they’re growing and that too dry or too wet when the berries are you can make them super high or low ph which can make some batches harder than others to work with.
I’ll note that you will need to add the yeast nutrient to the must to get it working. Also, I found that I needed to add more simple syrup just when the ferment began to slow along with an energizer to get it to take off again. I was told if I added champagne yeast at the second addition of sugar my wine would have a much higher alcohol content but I’m happy with where its at now. Prior to bottling I siphoned a small glass for Ma and I to try and we agreed that it needed just a touch more sweet so I did another small batch of simple syrup and added it, then waited a week to see if it was going to start fermenting again and it did not so I bottled it up. I’m watching the corks to see if they start lifting but so far all is good.
The wine shop at Pine Island closed so I lost my local access to the needed goodies, but the TC are full of places I’ll visit. I’ve really enjoyed doing the cranberry and will do it again in a year or two.
