![]() The proper dose for a 5 gal batch (19 l) is around 1/4 tsp (1.9 g) of Potassium Metabisulfite which is enough to add 50 ppm of SO2.Īfter adding the sulfites, you should wait 12 hours before adding the second additive which is Potassium Sorbate. It suppresses bacteria and other beasts and as a side benefit provides some protection against oxidation. Free sulfites help prevent oxygen in the finished beverage which prevents yeast and other organisms from gaining a foothold. Contrary to popular belief it does not kill yeast cells or stop fermentation, though when used in combination with sorbates (below) it can inhibit future fermentation. Potassium Metabisulfite is used extensively in wine and mead making to preserve and protect wines by adding free sulfites (SO2) to the finished wines. You can purchase and crush up Campden tablets, which are made from this chemical, but I prefer the powedered form as it is easier to measure accurately. The first one is sulfites in the form of Potassium Metabisulfite. Next we’re going to include two additives. Then you add two additives (below) to stabilize the drink, wait a few days and then add whatever sugars, concentrates or sweeteners you want to balance the taste of your beverage. Most often I will also let it age out because balancing the flavor is important and you can’t really judge the finished flavor until your beverage has aged and is ready to drink. First, allow your beer, mead or cider to fully ferment to completion. The Backsweetening Processīacksweetening is remarkably easy to do. However if you don’t balance that with some sweetness the fruit beer will be out of balance and either too acidic or lifeless. I find that fruits like blackberries, tart cherries, raspberries, red and black currants, and boysenberries come through best in a fruit beer because they are high in acidity and tannins. Again you may find either little to no fruit flavor in the finished beer, or else excessive acidity and tannins depending on the fruit used. Fruit sugars are highly fermentable and will ferment almost completely into alcohol. While the need to backsweeten beer is rare, it can be a useful technique when making certain fruit/dessert beers. Some residual sweetness is needed to balance the acidity and tannins in the fruit. Even fruits that come through well in fermentation like berries and currants will taste strange as they tend to be tart, acidic, and tannic. Since most fruits are a balance of fruit flavor and sweetness, post fermentation they can be faint and lifeless. Unless you start your mead or cider at a very high gravity, they will tend to ferment very dry. Why Backsweeten?īacksweetening is a technique used in hard soda, meads and ciders, particularly those containing fruits. In certain cases, backsweetening can enhance the flavor of many beers, ciders and meads. doi:10.Follow week we take a look at backsweetening – a technique commonly used in mead and cider making but not well known by beer brewers. ![]() Histamine intolerance: the current state of the art.
