SULFITES – FACTS Sulfites were in the first wine ever made even though sulfur

dioxide was not added. Sulfites are a natural byproduct of the fermentation process. The yeasts are on all grape skins and can generate naturally occurring sulfites in amounts ranging from 6 to 40 parts per million (ppm). It is impossible to have a wine completely sulfite free.

Using the compound sulfur dioxide inhibits bacterial spoilage, prevents oxidation and helps to preserve the wine's natural flavor. It makes wine more stable.

Sulfur dioxide can be used to arrest fermentation.

The US started requiring in 1988 that wine containing 10 ppm or more of sulfites put “Contains Sulfites” on the label

Red wine headaches due to SO2? White, rosé, red and dessert sulfite levels vary.

About a million people or .4% of the population are highly allergic to sulfites; highest risk are asthmatics and only about 5% of the group are allergic to sulfites; sulfite sensitive people are more common

TONGUE Tip of the tongue – sweet (sugar)

in front and goes away quickly Sides of the tongue – sour (acid)

on sides that makes mouth water Middle and back of the tongue –

bitter (tannin) on top back middle that is mouth-drying; builds over time

No salt!

WINE FAULTS Oxidation or maderization or sherried – color

and smell

Acetic acid – vinegar

SO2 – higher levels when recently bottled; excessive levels

Cooked

“Corked” – 2,4,6 trichloroanisole

Can’t tell before opening bottle

Can’t tell by looking at cork

Return it!

RIESLING CHARACTERISTICS

High acid; usually cool climate regions are best examples

Light to medium-bodied

Usually unoaked; may use large or older oak barrels for different mouth-feel, but rare for oak use that imparts flavor

Dry to semi- to dessert style

Look for citrus, stone fruit, petrol, flowers, perfume, honey, stony, minerality

Perception of sweetness and acid levels and balance

Chaptalization or suss reserve

Long aging potential
