Hobbyists do all sorts of things that have no basis is commercial production, which is our reality. If clarification is not necessary pre-distillation, why are the hobbyists clarifying?ĭo any craft distillers clear their wash before distilling why/why not? A small craft distiller is just a big hobby distiller with a license, and in a lot of cases, like mine, the hobbyists have many many more years of experience. Is it helpful to add finings to assist in settling the solids, particularly in molasses washes? Hobby distillers are all about settling their washes before distilling. ![]() Remember, extra aging will clear most haze so always err on the side of caution instead of trying to rush things.Well that's my question. Always start by adding less and move up towards the maximum recommended, if needed. Make sure to always follow manufacturer instructions on recommended dosing rates since over-fining your wine can cause color loss, stripping of valuable aromatics, and add unwanted flavors. Since the tannins can naturally bind with the positively-charged proteins, red wines may not require a negatively-charged fining agent.įining agents can be used during fermentation or post-fermentation. As mentioned a moment ago, tannins are negatively charged and are often prevalent in red wines. One thing to be aware of is the different approaches when making a red versus a white/blush wine. Bentonite and kieselsol are two of the most popular negatively-charged fining agents. Negatively-charged fining agents will help remove any positively-charged particles in suspension such as proteins. Egg whites, gelatin, isinglass, casein, and Sparkolloid are a few such positively-charged fining agents. Positively-charged fining agents are often used to clear the negatively-charged phenolics (and tannins) from wine that can cause astringency, as well as yeast and negatively-charged finings. Typically the negatively-charged fining agent will be added first, followed several days later with the positively-charged fining. Oftentimes, a positively-charged fining agent will be used in conjunction with a negative-charged fining agent to attack a broader range of compounds. Since electrostatic finings are the most prevalent among hobby winemakers, let’s focus on that category. Pectinase can help break down certain large carbohydrates that can cause haze in fruit wines. Finally there are enzymatic finings like pectinase. Absorbent finings are fairly rare, but activated charcoal and yeast finings are two additives that can soak up certain unwanted characteristics. ![]() Ionic finings such as copper sulfate and polyvinylpolypyrolidone (or PVPP for short) are best used in conjunction with an electrostatic fining to help precipitate out these compounds. Winemakers will sometimes use ionic fining agents to bind with unwanted compounds. Most fining agents winemakers think of fall into the electrostatic category, and can be classified as positively- or negatively-charged. Electrostatic uses natural charges found on certain particles to attract a cluster of opposite-charged particles to form, promoting faster settling. There are four principle types of fining agents: Electrostatic, ionic, absorbent, and enzymatic. Experienced winemakers often get locked into a fixed fining regimen and may not look around to see if there is something to troubleshoot a specific problem when one arises. For winemakers just starting out, the concept of adding finings can be a little daunting unless made clear in a set of instructions. This can be done either for appearance reasons or to remove undesirable compounds. Most wines will clear naturally over a long aging period, but certain wines will not.įining is the process of adding a substance to your wine to allow natural settling or clearing of organic compounds to occur more quickly. If you are pouring a cloudy wine, it is going to signal to the taster that it was a sloppily made wine. As hobby winemakers, we strive to make wines that rival commercially-produced wine, so we need to make extra sure that ours offers the same quality presentation. A wine’s appearance provides the first impression and can set the expectations for their tasting experience. When presenting a homemade wine to new house guests, presentation means a lot. ![]()
