Wine Central is proud to present a series of articles on “Do-It-Yourself Winemaking”, which features tips, ‘how-tos’, and advice on making your own wines. We’ve taken a short break for the “Medal Winning Performance, Affordable Price” promotion in February and are now back in action. This week is the third installment in our series—”Winemaking Kit Supplies”.
Winemaking Kit Supplies
You’re probably wondering what supplies and ingredients make up a winemaking kit. Here is a list of typical wine kit components.
- Potassium Metabisulfite prevents oxidation and suppresses bacteria and wild yeast. Kits typically have a concentration of 15-50 ppm (parts per million) at bottling. The legally allowable limit of metabisulfite for commercial dry table wine is 70 ppm. Sulfite is a respiratory irritant and shouldn’t be inhaled by anyone with asthma or emphysema.
- Postassium Sorbate (Sorbic Acid) prevents renewed fermentation in sweet wines and inhibits growth of mold and yeast. Combined with the sulfite in the kit it helps keep the wine stable for cellaring and ageing. Sorbate prevents yeast and bacteria from reproducing.
- Bentonite is a type of naturally occurring clay that when added prior to pitching the yeast, speeds the onset of fermentation.
- Isinglass is made from the powdered swim bladder of tropical white fish and dissolved in liquid. It’s gentle and won’t strip wine of its colour or aroma.
- Chitosan is derived from the outer shells of ocean crustaceans, but has no allergenic properties since it’s treated to destroy all proteins. It is protein free and often used for water treatment.
- Oak Chips or Oak Powder come from American or European oak trees and may be toasted. It adds wonderful flavours and aromas to wine.
- Elderberries are the dried fruit of the elderflower bush. Most come from Belgium. They add a plum-like flavour and a deep red colour.
- Dried Elderflowers are added prior to pitching the yeast. Used mainly for German-style wines, they add aroma and complexity to white wines.
