Hi all looking for some good advice
I made the first mistake of just grabbing some random recipe from brewsmith
It called for
5 tsp of nutrient at the start of fermentation just before yeast
And so I did that and am now wondering if that was way too much? Help!!!

Hello, and welcome to the forums!

There are many brands of nutrients out there, but probably the one most used by meadmakers are the products from Lalvin. They've got the largest body of literature regarding how to use them best, as well as their nutrient properties.

The major nutrient yeast need is nitrogen, which can come from both organic (in the chemical sense, derived from proteins) and inorganic (chemical salts). Diammonium phosphate--DAP--is the inorganic nutrient used most commonly in meadmaking. DAP is a pure nitrogen/phosphate salt. Organic nutrients are those like Fermaid-O from Lalvin; all the nitrogen comes from amino acids. There are hybrid nutrients like Fermaid-K that contains both organic nitrogen and DAP. For a more complete breakdown I'd recommend reading Ken Schramm's "The Compleat Meadmaker" or THIS (https://docs.google.com/document/d/11pW-dC91OupCYKX-zld73ckg9ximXwxbmpLFOqv6JEk/edit) more advanced writeup here. Nutrients are a hotly debated and constantly evolving, so I'm sure many other mazers will offer their opinions.

How much to use? That varies considerably between meadmakers. A very easy to use protocol using 100% Fermaid-O is the TOSNA protocol. (http://www.meadmaderight.com/tosna.html) Using all orgnaic nitrogen has certain benefits, but it does require ordering specialty nutrients online. If you can't get Fermaid-O, the same guy who made TOSNA made a similar nutrient protocol (http://www.meadmaderight.com/tiosna--inorganic-.html) using DAP and Fermaid-K. Notice that using these protocols effectively requires weighing the ingredients; get a scale. (https://www.amazon.com/American-Weigh-Scales-ACP-200-Digital/dp/B003STEIYY/ref=sr_1_1?ie=UTF8&qid=1472130476&sr=8-1&keywords=american+weigh+200g+0.01) They also absolutely require a hydrometer (https://www.amazon.com/Home-Brew-Ohio-Triple-Hydrometer/dp/B008S0KNZG/ref=sr_1_3?ie=UTF8&qid=1472130549&sr=8-3&keywords=hydrometer), which you should be using in your meadmaking anyway.

Thanks heaps for the reply and the welcome.
Well it is my first batch of mead as I had a lot of honey so I thought I'd give it a go.
I was given vintners wine nutrient and it's pretty potent stuff not sure to keep adding it or just stop now it's been bubbling away for 48 hours now!

How do you know the potency when none is given?
