"The
red wines are typically destemmed, not crushed (sounds like a James
Bond Martini) and fermented in simple open top fermentors and manually
punched down. They are barreled
very shortly after pressing and allowed to rest on their lees (sediment)
for many
months
before first being racked (transferred
from
barrel) and blended, typically for 6 to 10 months.
"The
Zinfandels and Pinot Noirs generally receive 16 to 18
months barrel time before bottling. Cabernet Sauvignon rests
in wood for 22 to 30 months, depending on vintage and provenance. Racking
of the reds is done principally for the purpose of blending and/or clarification
before bottling. This 'reductive' style of winemaking calls for longer
time in the barrel for full development and while having two or even
three vintages 'on the floor' at once causes cooperage congestion, it's
worth it. Over the past decade, Scherrer Winery Old & Mature
Zinfandels have proven their ability to age and develop gracefully in
the bottle.
"As
yet, none of the reds have been filtered, as this removes desirable
colloidal material, essential for the kind of development we desire
allowing the wine to achieve its highest long-term potential.
"Chardonnay
is whole-cluster pressed (like with sparkling wine) and for the Alexander
Valley fruit from my father's vineyard, stopped at very low juice yields,
giving more fine elements. With my two manually operated 'bladder presses'
(please forgive the connotation) this requires hours of valve turning,
button pushing, lever turning and scurrying about reminiscent of Dorothy
and her associates' first meeting with the man behind the curtain in
'The Wizard of Oz.' This is important to making high quality Chardonnay
(the taking of only the first and finest juice as opposed to the scurrying),
and especially critical for grapes from the less cool areas like Alexander
Valley. 100% barrel fermentation and malolactic fermentation, nearly
12-month barrel aging, and unfiltered bottling are typical for us. Again,
preservation of colloidal material here is as positive a factor as it
is for the reds.
"Our
Vin Gris is made by first bleeding a small amount of pink juice
from our red grape fermentations. This is done before significant yeast
activity or extraction of color and tannin occurs, perhaps by the second
or third day after filling the vat. What we get is the most delicate
expression of the grape. The juice is then fermented in very old barrels.
After primary fermentation, malolactic fermentation is discouraged by
the addition of a moderate amount of SO2. During
the winter, we choose which lots to combine for our Vin Gris, and 'rack'
them together in a tank, then returning the wine to the same neutral
barrels to further age on their 'lees' (yeast sediment). After several
more months in barrel, the wine is again racked off the 'lees', filtered,
and bottled. This usually occurs around the month of May following the
vintage. It is the only wine we routinely filter, to prevent malolactic
fermentation from occuring in the bottle.
"The
additional time in barrel on the yeast lees helps contribute to the
complexity and mouthfeel of our Vin Gris. We feel this is important
to the wine's potential, despite the fact that we are probably the last
to get our dry rose to market."
