Inside the box ($150 CDN):
  • bag of grape juice (16 litres)
  • 2 crushed grape pack (2 litres total)
  • 3.4 oz medium toast oak chips (16g/gallon) 
  • (RJS says 1 bag is american and the other french)
  • bentonite (30 grams)
  • potassium metabisulfite (4.8 grams)
  • 2x potassium sorbate (not used)
  • pectinase (1.5 grams)
  • chitosan (~50mL)
  • kieselsol (~10mL)
  • yeast (Lalvin EC-1118 - substituted BM 4x4)

 

Next time I'll ferment in a bucket with the skins/oak chips in a muslin bag.  Or posibly use two carboys and combine the results into a single topped up 5 gallon (19L) carboy.

 

Pitch Date: November 21, 2015

Lalvin BM 4x4

  • 6 gallons
  • OG: 1.111 - measured after stirring in grape pack

Day 18
Added pectinase, kieselsol, chitosan into the primary fermenter.  Unorthodox but the final step will be the last before a 6-9 month bulk age.
Day 22

Racked, degassed (45 mins, drill stir), kmeta added.  

Rack 3 gallons to bulk age (carboy topped is around 3.5).

Commence long term bulk aging. 

Tasting Notes (at 3 week racking):

-Aroma: sour cherry, plum, leather

Full body, med to med+ tannins.  Quite promising.
