We use this in almost all our brews.

I wasn't sure if it really did speed up fermentation but the 2 times I've used them, fermentation was relatively active within 4 hours & finished quicker than average.

I use this ingredient in every batch of beer I make. With all the time and ingredient cost involved, why take unnecessary chances? Get the yeast going as best with this nutrient.

I always use these 50\50 with Yeast nutrient and they work great for a vigorous fermentation.

Good stuff helped the fermentation.

Not sure if I can equate all of this to this additive, but bathes are beginning fermentation more quickly, fermenting vigorously and finishing early. I’ve already reordered some let’s hope this trend continues.

Simple to use, great results. Fuel to achieve the full fermentability every time.

Definitely makes a difference in my fermentation.

I have used this twice and I will never brew without it. You get a kick ass fermentation and starts in about 12 hours or less.

I have been using servomyces since I started brewing and I always have better results with a robust, more complete, and longer fermentation than when I run out and forget to reorder for my next brew. If you have sluggish fermentation, I recommend you give servomyces a shot.

I've been using this stuff for years. For me, it works better than yeast nutrient. Using the Servomyces coupled with a healthy dose of pure O2 has really cranked up my fermentations. Not cheap but not having a healthy fermentation is more costly in the end.

Honestly cant tell if it helped, but it sure didnt hurt during an intentional underpitch. Used it twice and excellent results each time

Love the ease of use of this product and it's apparent effectiveness... as the fermentation of my latest batch of porter will attest... I always worry about getting a complete fermentation even though I always make a starter and generally add a pack of dry just to be sure... I hit the final gravity on the button and I'd like to think the health of my yeasties is a big reason why!

Work like a charm with my Mead

Ever since discovering Servomyces and its benefits, I have been brewing with it since. Roughly 20 + batches now as of 2018 and I couldn't be happier. Really helps clear beer up and keeps the yeast healthy for re-use. Give it a go and see for yourself

I had to change from standard airlocks to blow off tubes after adding Servomyces to my wort. Huge difference in yeast activity when this is added. Highly recommend.

I've used a different nutrient in the past, with decent results, but the capsule form of the servomyces was convenient, and the results boosted my 9% winter ale through fermentation very well. It even finished the FG a few fractions lower than expected.

Great to help imperial brews finish when the yeast need to be extra healthy

I use it every time i brew

Have not used yeast nutrients before so cannot speak to cost efficiency between this and said yeast nutrients. Since using these, however, fermentation is quick, heavy, and long. Had to start using bigger carboys because it was fermenting so strongly and coming up the airlock, which had never happened before. Wouldn't consider brewing without, and ~$2.00 a batch seems reasonable.

I have used Servomyces in probably 30 batches, and each and every time it has yielded great results. I have never had a batch under-attenuate, and fermentation seems to be a lot smoother. The only reason it doesn't get 5 stars is because of the price.

This product made a noticeable difference in the vigor of my fermentation. Highly recommended.

Great yeast nutrient. I drop the capsule in with 10 minutes left in the boil.

I like having some in hand to restart stuck fermentation with a little more yeast slurry but...other than that, a jar of nutrients has no discernible difference.

Following the directions to the T, the capsule does not dissolve. To solve this, simply take it apart and sprinkle it in the wort. I've had no problems with my subsequent batches of beer as a result. Cheers everyone.

even if I use a yeast starter I still use these, they work great and I never worry about fermentation.

Every brew I have done with Servomyces has had a fermentation exactly how you should expect it. I'm not sure how much better it is than a simple yeast nutrient, but I don't like to change something already works for me. This product does.

very easy to use and I always get a good fermentation. Highly recommended for that extra bit of insurance for a proper fermentation.

Since using this product I have had the best fermentations ever. Srong, steady and sustained my effeciancy has gone up noticeable. Would not brew without it!

I use this in place of yeast nutrient as it has everything needed for a 5 gallon batch. Never have an issue with my yeast firing right up. White Labs makes some great products and is well worth the money.

These definitely are easy, but are very expensive relative to buying bulk nutrient components. I used to use these, but now that I make a starter every time I've found them to be unnecessary.I'd recommend them if you don't brew all that often and want convenience, and/or don't always make a starter.
