    • Acids & BalancesWine/Grape Must Adjustments: A number of additives are available that can be used to improve wine balance or quality. Major additions should generally be preceded by home trials and tasting of samples of the adjusted wines. Common improvements to grape must and wine include adjusting acidity and tannin levels. Tartaric Acid: Tartaric acid is the characteristic acid of grapes. Low acid grapes will benefit from tartaric addition; the wine will clear more readily and will keep and taste better. It should be added to any wine with a total acidity of less than 0.5%. As a rule of thumb, 1g per L will increase titratable acidity by about 0.1%.

    • Fining AgentsThe clarity, colour, odour, taste and stability of a wine can be significantly improved through fining. Fining involves the addition of a positively or negatively charged chemical agent to the wine to balance the charge of any suspended particles. The suspension will then agglomerate and settle out. The most frequently used fining agents are bentonite (aluminum silicate clay), activated carbon, gelatin, egg whites and PVPP (polyvinyl/polypyrrolidone). Many books on winemaking provide detailed instruction on the use of fining agents. Again, home trials on small volumes (100 to 200 ml) of wine are recommended.chromatography. Test takes about 10 hours.

    • Malo-Lactic BacteriaMalo-lactic fermentation (MLF) is the bacterial conversion of malic acid to lactic acid. Wines which have undergone MLF are typically softer (less acidic). MLF with commercial cultures is desirable in reds and some white wines to enhance stability. Many wineries encourage MLF to prevent spontaneous fermentation by less desirable bacterial strains. It should be noted that MLF is inhibited where free SO2 levels exceed about 30 ppm. Ideal conditions for MLF are lower alcohol levels, pH above 3.3, free SO2 of less than 30 ppm and a temperature above 20 degrees Celsius.
    • Malo-Lactic Test KitsMalo-lactic fermentation (MLF) whereby malic acid is converted to lactic acid and carbon dioxide, can be evaluated in a semi-quantitative manner through paper chromatography. Test takes about 10 hours.

    • Sulphur DioxideSulphur Dioxide (SO2): Sulphur dioxide inhibits yeast and bacterial growth and acts as an antioxidant in wine. These benefits are realized from the presence of molecular SO2 which occurs in free SO2. As a general rule, about one-half of the SO2 added to wine is present as free SO2, and the remainder occurs as bound SO2. Between 0.5 and 0.8 ppm of molecular SO2 is required to prevent spoilage and oxidation. It is important to note that the proportion of molecular SO2 in free SO2 decreases as the pH of the wine increases. The amount of free SO2 needed to achieve a molecular SO2 of 0.5 ppm and 0.8 ppm at various pH values is provided below: Free SO2 cannot be added directly to wine. Potassium metabisulphite (k, meta) contains about 57% total SO2, of which about 25 to 30% is free SO2. Campden tablets contain about 48% T SO2 or about 22-26% free SO2 Sulphur sticks which are burned, produce about 130 to 140% SO2 by weight. The proportion of free SO2 in total SO2, is also pH dependent with a greater percent available at lower pH. The following calculation can be used to estimate the amount of potassium…

    • Wine YeastWe strongly endorse the use of a commercial wine yeast in the fermentation of a grape juice. These wine yeasts have been carefully cultured to accentuate positive fermentation properties such as more efficient sugar-alcohol conversion, low hydrogen sulphide production, compact lees and SO2 tolerance. We recommend the addition of a commercial nutrient to reduce the likelihood of a stuck or sluggish fermentation and to minimize the production of sulphide (from nutrient deficiency). Nutrients should be added prior to the start of fermentation. For information and characteristics of each yeast, please visit www.lallemandwine.com.
    • Winemaking BooksNumerous books have been written on the subject of winemaking. We have selected a short list of books which we consider to be the best references for the amateur wine maker.

VARIETAL CHARACTERISTICS

Learn Your Grapes

Listed below are the varieties of grapes that we cultivate at Watson’s along with some characteristics. Many of these varieties are grown the world over and have been for centuries. Each has characteristics that make it a valuable facet of winemaking. In addition to “Varietal Characteristics”, each vine will produce fruit that also reflects its terroir and the care that it is shown. Choose the wines which you enjoy the most and be assured that Niagara-on-the-Lake and the Watson Family will provide you with the best grapes possible.

Chardonnay (mid) – This extremely versatile Burgundian variety has found a home in virtually all wine producing areas. High ripeness levels are easily achieved but good acidity is crucial for fine Chardonnay, especially if oak is used. This wine can handle oak fermenting and aging, and benefits from partial or complete malolactic fermentation (MLF).

Gewurztraminer (mid) – This pink skinned variety, most famously from Alsace is a variant of Traminer. Easily recognized by it’s heady perfume and lychee flavor. Off-dry wines are most common and Gewurz, due to it’s weight, is capable of medium aging. MLF and oak are not recommended.

Read About More Varietals

Kerner (mid) – This Riesling cross was Germany’s third most planted vine in 1990. The characteristics of this varietal are very similar to Riesling differing only by higher sugar and lower acidity. Its very slightly coarser texture, (than Riesling), is enough to make a varietal or it may be blended.

Pinot Gris (early) – A adaptation of Pinot Noir, this wine varies from crisp and refreshing to luscious and intense (in it’s dessert form). The berry colour ranges from P. Noir purple to P. Blanc greenish yellow, possibly on the same vine. This variety is also known as P. Grigio (Italy), Tokay-Pinot Gris (Alsace), Malvoisie (Loire), and Rulander (Germany and Austria).

Riesling (late) – Germany’s prized white wine grape ranges from light and delicate (cool climates) to fat and blowsy (hot climates). It is planted everywhere, including Argentina, Chile and California but it produces far superior wines from cool climates. The acidic backbone enables this great wine to age, while allowing vineyard characteristics to surface.

Sauvignon Blanc (early) – There are two distinct styles of this variety. Firstly, a non-oaked young, green, tangy, sharp, grassy and herbaceous wine (Sancerre) and secondly an oaked aged, distinctly rounder, more mature wine, with vanilla replacing some green fruit.

Vidal (late) – A French hybrid with thick skins, producing medium acidity and sugar. Very fruity and flexible enabling it to compose dry wines on one hand or the coveted icewine on the other.

Cabernet Franc (late) – This variety, a mutation of C. Sauvignon, enjoys cooler, damper and heavier terroir. Used mainly to calm it’s cousin, this wine is grassy, medium bodied, with soft tannins and notes of rspberry and blackcurrant. Oak aging will only benefit this wine.

Cabernet Sauvignon (late) – Thsi Bordeaux variety is the world’s most famous red wine. Unlike other grapes, no matter where it is grown or how it is vinified, the classic characteristics are notable. C. Sauvignon benefits immencely from extended maceration and oak, and is frequently aged for years to soften it’s tannins. It produces intense blackcurrant, cassis and chocolate flavours.

Merlot (mid) – Similar to C. Franc in that it prefers cooler and damper soils it does, however provide a better complement to C. Sauvignon. The soft, round wine is full of ripe plum, blackberry and other lush fruits. Merlot benefits from extended maceration and oak aging, but it is not demanded, and can be enjoyed earlier than the Cabernets.

Gamay Noir (early) – A simple wine with notes of fresh cherry, strawberry, and some banana and chocolate. Gamay has relatively high acidity and is meant to be consumed at an early age. This variety is often blended with Pinot Noir in many area of France.

Petit Verdot (late)

Shiraz (late)  – one of the oldest of the ‘noble grapes,’ this variety has gained great new popularity because of what the Australians have done with it. The wine can be dry, dark, and dense — or earthy and spicy, depending on the vintage weather. Ontario Shiraz tends towards blueberries, prunes, and violets. Fermentation should be long, cool, and oak-influenced.

Choose the wines which you enjoy the most and be assured that Niagara-on-the-Lake and the Watson Family will provide you with the best grapes possible.
