Petite Sirah Port Recipe

March 22, 2018

Yield:  4.5 gallons or 20 bottles


At Crush:

  • 5.5 gallons (55 lbs) macerated Petite juice with skins

  • 15 ml 10% Potassium Metabisulfite solution

  • 4.5g Opti-Red

  • .45g Lallazyme EX (or other pectin enzyme)

  • 5.85g FT rouge tannin (or other red tannin)

At Fermentation start:

  • 50g American oak chips

  • 50g French oak chips

  • 4.5g Fermaid-K

  • 10g Go Ferm

  • 8 g GRE yeast

At Fortification:

  • 2.3 liters 150 proof Everclear (or other high proof brandy) 

At Stabilization and Bulk aging

  • 3 separate ¼ tsp Potassium metabisulfite additions.



  1. Prepare fruit:  After grapes are crushed, destemmed and treated with 10% Potassium Metabisulfite solution, add enzymes and tannin. Cold macerate for 3 days.  Punch down daily.

  2. Start Fermentation:  Add oak chips and Fermaid-K.  Make a yeast starter with 100 ml water and Go ferm.  Mix into juice and set aside.  Keep temperature between 75-85 F.  Specific gravity should be between 1.080 and 1.1.

  3. Punch down:  Punch down for 2 days or until Specific Gravity reaches 1.030.

  4. Fortify:  ABV should be 9-11%.  Add brandy to raise ABV to between 18-20%.  Brandy should stop fermentation, retaining around 30% residual sugar.  

  5. Press:  After 2 weeks, press wine off skins and oak.

  6. Rack:  After 2 weeks, rack wine and add ¼ teaspoon metabisulfite.

  7. Add SO2:  At 3 months, rack and add ¼ teaspoon metabisulfite.

  8. Bottle:  After 6 months, rack and add ¼ teaspoon metabisulfite.  Filter and bottle.  Age at least 1 year in the bottle.


At fortification, we had just over 4 gallons at 10% ABV.  To dilute Everclear with 75% ABV, we blended these quantities using a pearson square:
