Brew2Bottle 100g Yeast Nutrient (Di-Ammonium Phosphate & Ammonium Sulphate)
Use sparingly! I put 125 grams in a 5-gallon brew. The first time I used it, I put in far too much, and because of the high dextrin content, which the yeast has to work hard to ferment, my brew stuck at around 020 gravity. However, it is excellent for that last stage of fermentation in the barrel, ensuring good body, residual sweetness, and good head retention. It's a good replacement for adjuncts if you don't have facilities to mash. I used to mash, but no longer have the equipment or the space. I used to condemn kits, and would not use malt extract, but modern kits are very good. Commercial breweries often use malt extract these days as part of the formula, so the public palette is more used to that flavour.
This is an excellent yeast, and a true top-fermenter. However it is rated to perform best at a relatively high temperature. I pitched at 40 degrees, and surrounded the tub with a duvet to avoid heat loss. It fermented out very quickly in just 3 days. However, I think the high temperatures introduced fruity esters, which some people like, and there are even commercial beers with peach and apricot undertones. Personally, although the finished beer is excellent, I will choose a lower temperature yeast next time, such as "Nottingham", which also has good reviews. For me a fermenting temperature of 20-25 degrees is much better, although slower. It's very good, but it depends what you are aiming for.
