Potassium Metabisulfite
Potassium Metabisulfite, (often referred to as "SO2", "sulfites" "meta", or "meta-bi") has several uses in winemaking. At the crush, sulfites are generally used to help control the spoilage bacteria and indigenous yeast that may already be present both on the fruit and in the winery (i.e. on the picking bins, processing equipment, tanks, tubing, etc). The amount generally used is enough to inhibit most of the unwanted organisms but not enough to hinder a cultured yeast, which has a higher tolerance to sulfites than most of the indigenous organisms do. This inhibition effectively "wipes the slate clean" for the cultured yeast to step in and rapidly colonize the must so that it can effectively dominate the subsequent fermentation. In addition, sulfites also help to inhibit the enzymatic browning of both musts and finished wines so that all of their delicate complexities can be preserved. Later, during storage and in the bottle, sulfites at the proper levels will further protect a wine by continuing to inhibit spoilage organisms, as well as by scavenging oxygen. Note that the exact amount needed to effectively do the job is determined by the pH of the wine. Refer to our MoreManuals! on Red or White Winemaking or one of the winemaking books that we offer for a complete explanation on how to properly manage sulfites. In addition, it's important to keep in mind that free SO2 levels fall faster in wood cooperage than in glass or stainless, so if you are using a barrel you will most likely need to manage sulfite levels more closely. The most common form of Metabisulfite is as a powder which is fixed with potassium or sodium. 1/4 tsp of Potassium Metabisulfite adds 50ppm to 5 gallons of must. Old Metabisulfite loses potency with time and should be replaced every year to assure that you are getting correct levels. You can use old Metabisulfite to make solutions for sanitizing equipment.

Tartaric Acid
MoreWine!'s Tartaric Acid is processed naturally in Europe from grapes and is the preferred acid for adjusting acid levels in wine. Be aware that a lot Tartaric Acid available to home winemakers is artificially made, comes from China, and does not integrate into the wine as well. Some of this tartaric includes the designation of "food-grade". Because MoreWine! packages this product you can be assured you are getting the highest winery-grade quality. 3.8g per gallon adjusts acidity by +.1%. As a note: some tartaric acid will drop out of suspension as potassium bitartrate if you are doing any cold stabilization. You might want to re-test total acidity after cold stabilization.

Citric Acid
Used primarily in sanitizing solutions to lower pH, therefore making the SO2 solution more effective. Use 1 tbsp per gallon along with 1 tbsp meta per gallon. Citric is not added directly to must prior to either primary or ml fermentation as its metabolism can lead to volatile acidity. A rough approximate of weight is 1 tsp = 4 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates. Domestically produced in the USA.

Potassium Carbonate
Potassium Carbonate is used to lower acidity levels in wine. 3.8 grams per gallon will reduce acidity by about .1%. Potassium Carbonate requires that the fermenter be stored cold for several weeks after application (please see our guides to Cold Stabilization in the documents tab above). During the period of cold stabilization the tartaric acid drops out as potassium bitartrate. Doing a trial run with a small amount is strongly suggested to determine exactly what the drop in acidity will be. Calcium carbonate can be used in a similar manner and does not require cold stabilization. However it adversely affects flavor, takes month to precipitate out of solution, and preferentially reduces tartaric acid first before affecting malic or citric acid. A rough approximate of weight is 1 tsp = 8.3 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.

Campden Tablets - Sodium Metabisulphite (25 Tablets)
An essential ingredient in winemaking. Sodium Metabisulfite, (often referred to as SO2, sulfites meta, or meta-bi) has several uses in winemaking. It is used at the crush, to help control the spoilage bacteria and indigenous yeast that may already be present on the fruit or the equipment. The amount used is enough to stop most of the unwanted organisms but not enough to hinder a cultured yeast, which has a higher tolerance to sulfites. This effectively “wipes the slate clean” for the cultured yeast to step in and rapidly colonize the must. Sulfites also help to inhibit the enzymatic browning of musts and finished wines. During storage and in the bottle, sulfites at the proper levels will protect a wine by continuing to inhibit spoilage organisms, as well as by scavenging oxygen. Campden tablets are Sodium Metabisulfite in an easier to measure format. Adds 75 ppm of sulfites at the rate of one tablet per gallon. These must be fully ground-up prior to use. Potassium Meta-bi in powder form, AD495 or AD500, is much easier to use if you have a scale and does not add sodium to your wine. It is possible the sodium could contribute a very small salty flavor. Especially when making white wine it is preferable to add potassium over sodium since added potassium can later help with cold stabilization. For more information refer to our MoreManuals! on Red or White Winemaking or one of the winemaking books that we offer for a complete explanation on how to properly manage sulfites.

Glass Wine Thief - Economy
A unique, functional variation of the traditional glass wine thief. We ordered these from eastern europe where the pricing/quality is great. The design was supposed to look exactly like our traditional thiefs we have made locally in Berkeley, California. Thus we used a picture of the original thief in our latest catalog. But alas, when they arrived they looked unlike any wine thief we have seen. But.... they work fantastic so we are happy and we think you will be too! Upon further testing and working with this thief, it has become clear that it can be tempermental about which carboys it fits in. If you'd like a glass thief for a carboy, we have to recommend the MT345. This still works great for barrels, even stacked ones! 1" in diameter, 10" from the bend to the tip and about 14" total length.

Pipette Filler
Safety Bulb pipette filler for use with solutions that should not be mouth pipetted. In general, it is best to use the filler with anything that is not a wine sample.To Use: Squeeze filler and place on top of the pipette. Place the pipette in the solution, allowing the bulb to re-expand, drawing liquid into the pipette. Draw liquid up past the point in the pipette that you would like it filled to. Now, being careful not to draw up excess liquid or squeeze out what you have in the pipette, quickly remove the squeeze bulb and place your index finger tightly over the top of the pipette. Now by gently lifting your finger, you can allow the liquid to run out to the level that you're looking for.**Tip:** Be careful not to draw your liquid up into the filler. Many chemicals that are used around the lab can degrade the filler and cause poor sealing, making the filler harder to use. A great way to get a feel for the tool is to practice for a little while with some water, until you can easily remove the filler and seal the pipette with your finger.

Ascorbic Acid
Due to high demand, this item is currently out of stock. Be the first to receive your items by placing a pre-order today. We will automatically ship this to you when we receive more inventory. Ascorbic acid is a quick-acting and powerful antioxidant that is used in white winemaking to protect against light and short aerations, such as racking and bottling. It works by rapidly converting dissolved oxygen into hydrogen peroxide before it has a chance to react with oxidative enzymes and cause browning. However, this hydrogen peroxide itself needs to be removed from the wine in order to avoid the very phenomenon that was trying to be avoided in the first place, namely oxidizing the wine. The answer lies in always making sure that the free SO2 levels are correct, both before the ascorbic addition is to be made and after. (Note that "Titrettes" are not accurate enough for this, and that a more precise means of determing free SO2 is needed, such as an Aeration-Oxidation set-up). Addition rate is around 50 mg/l (ppm) as long as the free SO2 is maintained at 30 mg/l (ppm). A rough approximate of weight is 1 tsp = 3.2 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.

High Quality Made in USA Thermometer - 2 in. x 12 in.
Are all bi-metal thermometers created equal? Not really. The problem with most bi-metal thermometers is that hang ups occur and you have to tap the thermometer to get an accurate reading. The cause of the problem is that the bimetallic helical coil in the stem of other bi-metal thermometers is tack welded to the stem itself. Our new line of thermometers feature a super sensitive bimetallic helical coil suspended from a copper coated bushing fixed in the stem. This superior design provides a faster response to temperature changes and assures more accurate readings. What does this mean? You don't have to tap the gauge with your finger as much. They are also accurate to 1% of the total range, feature a polished 2" 304 s/s housing, a hermetically sealed water proof case, and glass face. The range is 0-220 °F and -10-100 °C. The 12" stem is 1/8" stainless steel. This is a very different thermometer than some of the other low quality 2" x 12" thermometers that are currently on the market. This dial thermometer should be calibrated at 150 °F.
