Ok, this is my first batch of mead! I used this with some energizer and the yeast. It started to bubbling about an hour after I put it all together.

great for brewing and sourdough starters!
I brew and my mom makes bread, i mean they go hand and hand. She noticed her starter was a little sluggish so i added a 1/4 tsp of this to it and boy after a few hours even the next morning it was bubbling like a gassy volcano!
It's like a yeast aphrodisiac. cue the barry white music.

it took a while
It took over a week before the product arrived. That's kind of a bummer. Everything else was good.

How not to use ...
I'm afraid my rating is based on no experience - hence 3 stars. Though I purchased the product, I tried putting the suggested dose in my starter and killed all the (expensive!) yeast. Fortunately I always keep a few spare dry yeasts on hand, so I salvaged the batch. The point is - don't add this to your yeast starter! Only add it to the wort (not sure if this needs to be added at the beginning of the boil or not ...). I know, it's a newb mistake, but other newbs might need to know. :)

When should I be adding the nutrient? During the last part of the boil, or when the wort has cooled to pitching temperature? The directions on the package only mention 1 tsp/gallon. Thanks!
T O on Aug 21, 2016
BEST ANSWER: I add mine in the carboy, at pitching temps. I also use way less than 1 tsp/gallon, more in the neighborhood of 1-2 tsp / 5 gallons and have seen more active, quicker starting fermentations still. With wort in the carboy at pitching temps, add nutrient and yeast, cover and shake for a few minutes and you should be good to go.
When pitching into a fermentor, do you have to boil it in some water first to sanitize?

How long does this stuff keep? I've bought several of the small 2 oz size over the years, and depending on available time for brewing and real life stuff, it would sometimes sit for years before I could use it. Recently bought some from NB and after only a few months, it started giving off a very strong ammonia smell (that I didn't remember being there before) and it looks like it has changed color and gotten noticeably darker. Are some lots of it prone to "going bad" quicker?
M I on Feb 11, 2016

Thanks for contacting us. The nutrient shouldn't spoil. However, if it becomes exposed to moisture in any way (e.g. humidity), it can be colonized by wild microbes that will start to produce that ammonia smell. While certain batches are not more prone to spoilage, it is not uncommon to have a varying longevity across vials due to environmental conditions.
I see that one reviewer says to use it in the starter, another says the fermentor. There aren't any clear directions on the package. When should it be used?
Ben H. on Oct 7, 2015
BEST ANSWER: I use it in both! A little dash around a 1/4 tsp in the starter is a great idea...then you can put the recommended amount at the last 15 minutes of the boil. The healthiest yeast possible result and that makes the best beer possible.
I see there's both "yeast energizer" here as well as this "yeast nutrient", how to choose? Different applications? Use both?

Yeast Energizer
BEST ANSWER: A yeast nutrient is used to boost or aid the fermentation process. The energizer is used to stimulate or restart a fermentation. If your yeast dies in transit or does not kick off in the first place, this can be added to a batch with a pack of new yeast. Along with any nutrients that you might think is required.
How many teaspoons do you get out of that little jar?
Randy on Jan 11, 2016
BEST ANSWER: I had the same question. I bought the 8 ounce, just to make sure I had enough. I measured the volume in a graduated marked container. I found I had 50 teaspoons full for the 8 ounce pack. Take this total amount and divide by 4 and that will give you the amount of teaspoons for the pee wee 2 ounce jar. Comes out to 12.5 teaspoons. The 2 ounce jar will treat 12.5 gallons.
