I've got a 2 gallon bucket and one gallon carboys. Eventually I'll move up to larger batches, I just need to find some recipes I like and get some experience under my belt.
The bucket is fine for the primary, but I highly recommend you pick up a Little Big Mouth Bubbler (only $25) from Northern Brewer for your secondary. You're going to be miserable dealing with fruit in a gallon carboy. And make sure you crush the cranberries after they're cold macerated, because the skin is so tough that all the juice released won't be able to escape without crushing.
CRANBERRY
Primary
3 lbs 13.9 oz of your preferred honey
2 lbs cold macerated and crushed cranberrIes in a mesh/muslin bag
5 lbs 6.1 oz filtered spring water
Pitch
126 mL filtered spring water, 6.3g GoFerm maintained at 85-95°F, then add 5g Lalvin K1V-1116 yeast. This SG and volume would call for 3g, but the benzoic acid in cranberries inhibits fermentation, so you need extra yeast to compensate.
Let bloom 10 minutes while maintaining this temperature, then remove from heat and add primary must every 5 minutes to acclimate it to the gravity until it reaches room temp, then pitch into the primary.
SG: 1.102
Fermentation
Pitch 1.5g of Fermaid O at the 24h, 48h, 72h, and 7-day mark. Ferment until two hydrometer readings a week apart show no change in SG (hopefully at/below 1.000), then let it sit 2-4 weeks until yeast has floculated and batch is nearly clear. Then stabilize with the correct doses of potassium metabisulfite and potassium sorbate without stirring, and rack off the yeast and fruit into the secondary. The above recipe makes 1.4 gallons so you can avoid headspace in the Little Big Mouth Bubbler I hope you'll buy, without sucking up lees.
Secondary
In another muslin bag, drop in the other 2 lbs of crushed, macerated cranberries, and let it sit on them two weeks, then pull out the bag.
Because of the high benzoic acid and tannin content of cranberries, you'll want to backsweeten this pretty hard, and oak it with wood with lower tannic value.
I'd backsweeten to 1.032 or so. Once you get to this step and have the final gravity, I'll help you with the calculations to achieve this. Stir in the honey gently to avoid introducing oxygen, until fully dissolved and the stirrer comes out with no honey. You may want to stir, wait 24 hours to dissolve, then stir once more to make sure all the honey is off the bottom.
Let it sit on 1/3 of a dark (less tannin) toast French oak spiral for 1-2 months, but taste it weekly until it has the wine barrel taste you desire.
Finishing
Once oaking is done, fish out the oak and let the secondary sit for at least a month. Taste monthly if aging longer. Once it's enjoyable, check for perfect clarity; if it still isn't clear, use two-step DualFine (step 1, stir, wait 24h, step 2, stir). When it's crystal clear, drop in another dose of potassium metabisulfite without stirring, let it incorporate 24h, then rack it into bottles and cork.
That took a long time to build and write, and it's past my bedtime, so I'll have to build your triple berry recipe tomorrow.
