          MB’s Viognier 1/2-breed
MB’s
                   PORT
MONGREL
STYLE = PORT (Ruby-like)
   Varietal = Viognier
 Appellation = 100% RRV
Trentadue Winery sells
  a lovely viognier port
  that I am using as a
 model for my Viognier
           Port.
Alc= 18.5%
RS = 11%
TA = 0.5g/100ml
pH = 3.83
Grapes
• Viognier grapes are difficult to grow
  and typically produce low yields.
• Trentadue uses grapes from the
  Russian River Appellation,
  specifically from Slusser Ranch
• Some other successful Viognier
  vineyards are in Santa Barbara, Paso
  Robles, & Sonoma.
Whole           Add port
Harvest at
27-29 brix       cluster         wine yeast
                  press


                                         Ferment to
                                         1/2 grape
                                         sugar
       Bottle



        Filter                         Add
                   Cold                “aguardente”
                   stainless           to stop
                   steel for 8         fermentation
                   months
Harvest at   Grapes are
27-29 brix
             harvested with a
             high sugar
             content, half of
             which will remain
             unfermented.
             Port is very sweet!
             Analyte- Sugar via
             refractometer!
Whole
cluster
 press    Grapes are crushed in whole clusters.
          Juice is in stainless steel tanks.

          Analyte - Sugar via enzymatic
Ferment to
Add port                1/2 grape
wine yeast              sugar

 Analyte - Sugar!! The fermentation must
  be stopped while much sugar is left.

 True ports ferment to 1/2 of the original
   sugar in the juice.

 Trentadue’s port has RS of 11%.
 Mine will have 8% RS like the port
   produced by Bonny Doon because I
   prefer it less sweet.
Add
“aguardente”
to stop
fermentation

   “Aguardente” is a distilled
     wine with high alcohol
     content (40%-80%).

   Analyte- alcohol content of aguardente
     and 1/2 fermented wine.
   Final alcohol content is determined by this
     step!! Usually 18.5%
Cold
             stainless
             steel for 8
             months


A short “reductive” aging.
Filter       Bottle




Microbes are dead due to high alcohol
 content, but we filter to make it pretty.
                                             MB’s
                                             MONGREL

I will use a screw cap, so no cork QC.
Analytes- Alcohol & RS for labeling.
