2nd Run with Grape Pack
* If u've never made wine, u will NOT understand. If u've made regular kit, u may still not understand till u have the grape pack in your hand. *
结果导致(......续):
4. 因为新增葡萄包,大部分新的酿酒设备,改用更大的桶 for Primary Fermentation。(Not sure, may be something like old ~35L bucket ==> 45L bucket)
(if u have old regular bucket, be careful with 12L; do not do 18L on hot summer days, WILL overflow.)
5. A lot of people switch over to Grape Pack Kits, then do 2nd run with used Grape Packs.
___________________________________
Today most wine kits manufacturers carry Grape Pack kits. Besides regular instruction (i.e. pour content of Grape Pack into disinfected mesh bag included in kit), u can:
1. tie beer/coffee mug(s) to mesh bag to "sink" the bag (instead of floating all the time); or (my last trial with 2 coffee mugs was insufficient)
2. use the stirring spoon to "hold down" the bag; (I can't get this to work myself)
3. pour entire Grape Pack into the must in primary bucket on day 1, right before adding yeast pack.
[This method is completely messy when u transfer on ~Day 7. Forget siphoning, it will not work due to too much solids inside must. I borrowed a conical strainer from a professional kitchen(~picture below), found it too messy, not worth my trouble. Forget using Funnel with Strainer in picture below also, too "light duty".]

How to do 2nd run:
1. Right after siphoning/transferring must from Primary to Secondary, just start your next batch right away in same bucket, no washing nothing. Skip the yeast in new batch, the yeast left in Grape Pack is more than sufficient. Do prepare for a much faster fermentation, could be as quick as 2-3 days in Summer hot days.
2. If not starting 2nd batch right away, put used Grape Pack into disinfected freezer bag and freeze it right away. Whenever u want to use it, bring it back to room temperature before throwing it into new batch. I haven't try this, not sure . . . .
a. Freezing will weaken yeast in used Grape Pack, not sure if it will be sufficient to start a new batch.
b. If it were me, I would wait till new batch start fermenting before putting in defrosted Grape Pack. Same yeast would be better.

My Results:
I've only tried CC 18L and CC 12L Grape Pack kits, red only. I don't have the breakdown of the 18L now, but the grape pack is 2-3 times the size of 12L. The used Grape Pack from 18L Amaroni did significantly improved the 7.5L Valpolicella, brought the Valpolicella quality above all 12L kits. This Valpolicella Ripasso is a classic combination and worked out EXTREMELY well. Other trials were less favorable, other 18L only brought 5L up to a 9L quality (only tried 2 others).
(Everyone who knew about this did the Valpolicella Ripasso, there were so many of us that actually brought up the price of Valpolicella kits)
CC 12L consists of 10.5L must and 1.5L grape pack. The used Grape Pack from 12L did bring 5L kit up to ~8L quality. It did improved Costco PL kits, both color and body but insignificant to Costco AR kits.
***** Quality of grape juice/kits vary every year, MY results is for reference only, it MAY NOT be the same for u! *****
