Do i need acid blend?

M doing my first batch of mead. I have everything but the acid blend. Is it neccassary?

Usually it isn't. Honey is very acidic, and generally mead does not require additional acid. I've never used it, personally.

I mix my own, using the suggestion from Ashton & Duncans book "Making Mead" (long out of print, but used copies can be found). It's 2 parts malic to 1 part tartaric.

I only used it after the ferment has finished etc, then its added incrementally, too taste.

I've made mead and never used it you should be fine

Is it necessary? No.
Can it improve a mead? Absolutely.

I don't add it to all my meads, but I do add it to quite a few. Too little acid can leave a mead, cider, or wine dull and lifeless. A little acid can brighten the flavors. I look at it like adding salt to a dish or lemon to a piece of fish. The food was okay without it, but the salt and lemon can improve it. Like Fatbloke, I usually add it to taste post-fermentation in my meads. I add a measured amount to a small sample. When I like the blend, I scale it up for the full batch.

Thanks all!
