Crushing 2010 Gewürztraminer
Since he’d be getting a smaller load of Gewürztraminer from Mokelumne Glen Vineyards than expected, Borra winemaker Markus Niggli deviated from his normal procedure by “chaining” his crush equipment together: crush, destem, then straight to press.

Fresh 2010 Gewürz juice

A glass of sweet Gewürz juice
The Gewürztraminer from Mokelumne Glen Vineyards came in with sugars at 23˚ Brix, acid at 3.7 pH and lots of berries showing a reddish tint, accounting for the brownish tint to this glass of freshly-pressed juice.

Preserving Flavors
With this week's weather threatening to crack 100˚ for days in a
row, nearly-ripe white Mokelumne Glen
Vineyards Gewürztraminer was facing the very real possibility
of raisining and damaging sunburn.
Even though the buyer of the Gewürz, Borra
Vineyards winemaker, Markus Niggli, didn't think flavors were
optimal, he called in the crew to save the grapes from over-cooking
by picking them last Thursday.
In the cool of the morning, almost three-quarters of a ton were
harvested and delivered to the winery in two bins. (By contrast, I
was picturing a line of trucks carrying 20-ton grape loads waiting
to be weighed-in at Woodbridge
Winery.)
Since he'd be getting a smaller load than expected - now a
common observation with the 2010 harvest - he deviated from his
normal procedure by "chaining" his crush equipment together.
Rather than dumping all the whole clusters directly into the
wine press, Markus hoped to get more juice from the batch by first
crushing and destemming the grapes and then immediately spreading
the crushed grapes into his press.
Such an unusual set-up meant that his two-man crew would spend
more time getting the equipment ready and cleaning up afterwards
than on crushing such a small quantity of grapes. These small lots
drive cellar crews crazy, feeling like they didn't accomplish much
for all their work.
Pre-crush, the Gewürz tasted, "Sweet. With a floral aspect,"
said Markus. The sugar came in at 23˚ Brix, with acid at 3.7 pH and
lots of berries showing a reddish tint, explaining why the pressed
juice was more brownish than the usual green tint of white wine
juice.
With quality control in mind, I grabbed two wine glasses from
the lab and scooped up enough juice collecting in the pan under the
press to get a good taste. Markus assessed, "Slightly green.
Tannins are there. TA is low. 3.75 pH. Will need acid. If I get a
barrel and a half, I'll be happy."
Provided the Gewürz turns out nicely after a 3-week cool
fermentation, "I hope to be able to put it into the Borra White
Fusion again this year as 3-10% of the blend," said Markus.
