When I racked the mead out of the fermenter, it smelt more like cheap tequila than wine. I still remember the first time I home-brewed mead. Dry hopping will also help cover up unwanted fruity flavours.īottle conditioning also reduces the harsh alcohol smell considerably. It may not be the best beer that you’ve ever brewed and it probably won’t taste as you expected, but it might not be too bad either.Īfter fermentation has completed, if you leave the beer on the yeast for a week or two, it will generally clean up some of the esters and fusels. If not, just let things run their course and bottle or keg the beer as usual. If you notice that the temperature is rising, you might have time to rig up one of the solutions described below. If this happens, don’t panic, there’s no need to dump the batch at this stage. Many homebrewers leave the fermenter in a spare room or cupboard without temperature control, and if there’s a sudden heatwave, the beer can soon get too hot. Can you fix beer if it’s fermented at too high a temperature?Īccidents happen, and letting the fermenter get too warm is a pretty common mistake. Fusel alcohols are also believed to be responsible for hangovers, although there is some debate about this. Most homebrewers compare the smell of fusel alcohols to nail polish remover or paint thinners. Although some of these fruity flavours are expected in French Saisons and some Belgian beers, they are inappropriate for most ales and lagers.įusel alcohols are alcohols which contain two or more carbon atoms and are sometimes referred to by homebrewers as heavy alcohols because of their higher molecular mass.Īlthough fusel alcohols are always present in beer and wine, they impart a very harsh alcohol taste in larger quantities. The most common by-products generated when you ferment beer too warm are esters and fusel alcohols.Įsters give the beer a fruity taste, usually described as being similar to bananas, although apples, pears and raisins are also frequently mentioned. When yeast grows too quickly, it also depletes the number of nutrients present in the wort, which also stresses the yeast, causing it to generate even more unwanted by-products. This causes the yeast to create by-products which spoil the flavour of the beer. What happens if you ferment beer too warm?Īt higher temperatures, yeast grows more quickly, and fermentation is more vigorous. To save time, we’ve compiled a list of the most popular yeasts used by homebrewers. The ideal temperature for your yeast should be printed on the packet, if not you will be able to find it on the manufacturer’s website. What is the correct temperature for yeast? You should also bear in mind that fermentation is an exothermic reaction, which means that the wort will usually be a few degrees warmer than its surroundings. Each strain of yeast has an ideal temperature range, and you should keep the fermenter within this range throughout fermentation.įermentation temperature is especially critical during the first forty-eight hours since this is when fermentation is most vigorous, and the yeast is most active. The correct temperature for fermenting beer depends on the type of yeast you are using, which in turn depends on the style of beer you are brewing. Electronic thermometer What temperature should beer ferment at? In this article, we take a look at what happens if you ferment beer too warm and how to prevent it from happening in the first place. Higher temperatures also produce more fusel alcohols which can make your beer taste of paint thinners. When beer ferments at too high a temperature, the yeast creates more esters leading to fruity off flavours, similar to overripe bananas. If the yeast gets too cold, it may stop fermenting all together. At the higher end of the temperature range fermentation is more vigorous. Yeast has a temperature range where it works best. Please be patient as more links will be added you have to start somewhere.Temperature control during fermentation is one of the most critical factors in home brewing and significantly impacts what your beer tastes like.
