Alright! As promised, it's time for details. After all this trouble n work i finally put my pineapple brandy ferment down.
I'll start off by explaining what i did, and why. When i've done these fruit brandys, if i can call them that, i'm still pretty new to the game so not a seasoned veteran brandy producer (Looking at you Cranky and Jimbo) But, i've used everything i've learned here to guide my decisions, and put as much effort into the fermentation side as i can muster, now it will be left up to my skill as a distiller to finish this with finesse and care, so it is worth my time and work and a success. Of course, as we like to say on here, the only person who has to like the distillate is me. But, I try to hold myself to a high standard and make the very best drop i possibly can.
So pretty much any time when i Pot still, i do stripping runs and accumulate 4-6 runs worth and do a spirit run, slower, and collecting in numbered jars to do the cuts a couple days later after airing. For UJSM, AG, rum, and most other recipes this is not an issue. But for fruit brandy, getting enough wash to do a run can be more difficult and expensive. I know that the key to successful fruit spirits in this style, is either distilling on the fruit, which isn't possible for me with internal elements, other than my sachets, or using fruit juice or puree. From my research and light experience, that best gameplan by far is to use as pure of juice as possible. No added sugar, no watering down. The more you add other products, adjuncts, sugar or water, the less fruit flavor you will retain in the final distillation.
So, my method has been to do 1.5X runs. In order to do a run of any kind, the minimum i like to use is around 4-5 gallons. So, i try to do 2 fermenters worth of any recipe. My fermenters are from brewhaus.com and are 25L at max, or 6.6G. I could do two spirit runs, but this would yield me around 2-2.5 G. Low wines. This just isn't enough for my still, it would barely cover the bottom element. So, I could do a single run, but i haven't really been a fan of the results of a single run. Thats where the 1.5X run comes down. If i do a single run, my aggregate keeper abv would be around 40% ABV or less. This just isn't enough for aging on oak the way i like to do it. I prefer to be in the 50-70% range. So if i have 2 runs worth, and do one as a strip and add it to the second for a spirit run, i think it accomplishes my goal. The spirit run produces distillate that's high enough in abv for aging, has some of the refinement of a double run spirit, and the flavor of single run wash. To me, it's the best way to go in this case.
In this case, i tried to get as much fresh squeezed pineapple juice from real pineapple as possible. I cut, cored and juiced 7 cs. of pineapple in total, and every case is about $15 and 25#. The juicer as i mentioned was terribly inefficient and left me with 6g plus of pulp holding a ton of juice which i struggled mightily with in squeezing in paint bags in the mop wringer. BUT... squeeze i did... and my total take from all the pineapple was about 29L. This would have been enough for one very full ferment. So, method was this:
I filled up one fermenter with 21L of the real pineapple juice, which had a final SG of 1.050. Not bad.. if it ferments to 1 it will be 7% alcohol. The other fermenter, i put in the remaining 7 or so Liters of fresh real pineapple juice, and to this i added 4 cans @46oz each (5.75QT total) of Dole Brand Pineapple juice (SG 1.054), and 7L of water with 2# Sugar dissolved in it. So this fermenter ended up being 19L @ 1.055. My plan is for the better ferment (the one from pure pineapple juice) will be the spirit run, added with the low wines that i strip out from the "lesser" ferment of 19L with the sugar, h20 and canned juice. I thought it wiser to save the better ferment for the spirit run.
Both ferments are sealed up and ready to start working.
My thoughts on yeast: I've got bakers (for rum and yeast bombs), DADY (for neutral and currently whiskeys, though i'm looking for a new whiskey yeast) a few packs each of EC-1118 and K1-V1116. I thought i'd like to do both with 1116, but i've only got two packs. Now, 2 5g packs, really should be enough for 2 ferments in the 5G range. But i always tend to over pitch. So, i used the EC for the strip run and K1 for the spirit. I chose them because i've read and seen that they produce clean, well delineated cuts, and do well with fruit. They're both very hardy and versatile yeasts, that do well in many conditions, including temps, yeast nutrients, PH, other environmental factors, etc etc. They're also both Killer Strains, so if there is any Wild yeast present the EC/K1V should viciously murder the Wild yeasties, then take over. Each ferment received a small does of yeast nutrients, including Fermaid K, DAP, Epsom, and Vitamin B. Along with the yeast choice(s) i wanted to be as sure as possible i'd have successful fermentation. I'd hate to lose all the work i put into this.
And that's pretty much it. I'm not sure what aging protocol will be. Hope fully my keeper cut ends up being right around 65. I'll probably stick to just toasted wood, so as to not overpower the fruit.
I'll post results when we get there!
Once again, I f ing love this hobby. It is a heck of a lot of work at times, which can be good and bad... but i love it so much. I'm sure i'll continue to love it more as my aging stock ages!!
Wish me luck!!
