Andrew and Jack,Many a mel I have made, always added the fruit at the 1/3 sugar break. Alcohol % is high enought to take care of any hitchers
Dale,Andrew and Jack,
I understand your answers. However, does the simple honey/water must have enough nutrient value to sustain a strong fermentation? My past few batches have included added yeast nutrient, but I read somewhere that this adds a slight off taste. I was looking for a recipe that leaves out the (artificial) nutrient.
Maybe this is a more appropriate question: What is in the powdered yeast nutrient? (mine is called Fermax) Is there really any reason to want to leave it out?
Thanx for the help.
Indeed. However yeast do bring many nutrients along with them from their propogation which are often good for several generations of budding before they begin to deplete.Ben,
I have to disagree with you on the nutrient bit.
honey has almost no nutritional value for the yeast other then food, now imagine if you only ate fructose/sugar your entire life, you would be very unhealthy. yeast need nutrients, vitamins, and trace minerals to be healthy and not make off flavors or stall out.
Since that IS the case (and I agree, see reply above), whence the blanket nutrient requirement? Also important to make a distinction between "starter" and simply rehydrating, I think we're talking here about a starter (the intent of which is to begin yeast metabolic processes, build nutritive reserves and increase cell count). In dry yeast this has already been done; they can ferment even a unadulterated sucrose solution to completeness because they're nutritionally prepared before being dried out and packaged....because the yeast are packed with amino-acids and other food stores to get it going from go.
Nutrient and DAP (also called "energizer") are totally different products with different intended uses. Nutrient, as you say, is usually ultrasonically exploded yeast and is intended to provide a broad nutritional (as opposed to energetic) needs. Think multivitamin. DAP, Diammonium Phosphate, and related products such as urea and other energizers are solely to add nitrogen as an energy source. It will not support a nutrient-deficient must, and is usually reserved for trying to shake awake a stuck ferment. Simply having fruit in a must usually will meet nitrogen needs for stressful musts, but energizer can be helpful for very high-gravity traditionals.you want to use nutrient at the beginning of the fermentation so the yeast metabolizes all of it, but mostly, yeast nutrient is processed yeast hulls. the DAP is good for feedings. but feedings should end before your 1/2 break
Me neither. It'll usually come out as a mild phenolic character, which can have many causes. So...i never rule out that someone has better taste buds the me, but out of all of the competitions, never had a comment of "tasted yeast nutrient" in any of the mead, beer, cider or wine i have made.
I agree totally, and while I sometimes wax pedantic I hope everyone understands I'm trying to bring my experiences and information out for discussion and I am nowhere near the authoritative opinion. So I can't be sure that nutrient use or energizer use have been the proximate cause of off-flavors in meads. But, in my experience, I think my meads improved and became more consistent when I started reserving the chems for stressful meads such as ones with high gravities, low pH, etc.i worked in the industry for a while on the production end and in the retail end. it is the retail end of home-brewing that taught me to never discount others experiences. they have a process that works for them to get the results they want. i can never argue with that, i just simple pass on the knowledge i have gained from working in the commercial production end, i can tell you the micros are generally using nutrient. they want consistency and keeping that yeast health keeps them from doing wonky things.
Thank goodness! I think there's a lot of room for mazers to use different techniques, and I don't really believe in right or wrong practices. Just accurate or inaccurate information. I've had customers who wouldn't touch anything besides their Ziplock-bag "pruno" (prison hootch with bread yeast and whatever sugars they could scrounge, such as prune juice). Some folks think using sulfites is just this side of joining the Taliban, and some folks think anyone not using sulfites is a Luddite dreamer who's straight-up sacrificing quality for misplaced New-Age idealism.like i said i never call anyone methods wrong if they get the result they want. but i am always going to advocate for what i believe is the correct process. please don't take it the wrong way.
