Default Using two yeast packs

I'm looking at making a black ipa and they recommend using a yeast starter. My question is if I could just use two packs of yeast instead. Looking at using safale us-05 ale yeast

Thanks

If you are using US-05 one pack is good, no starter required. Oxygenate your wort and you will be fine. Yeast starters are usually only needed with liquid yeast.

What does the OG look like in your recipe? A starter is very easy to make and would only cost you about 4-5$ for a lb of dry malt extraxt which you could use for at least five times to make five starters for your next 5 batches. And it will definitely improve your fermentations as less lag tome and off flavors produce because the yeast will work alot less to get started eating those sugars.

That said if your gravity for this parricular batch is low enough the two oacks of safale ahould get it done nicely.

But you could save money just buyin the DME and making the starter instead of two yeast packs. A much wiser investment if you are looking to brew on a budget or enjoy stretchin your brewing dollars.

I didn't think a starter was necessary for dry yeast. The OG is 1.075

Assuming a properly-stored pack of yeast (90% viability), the Mr Malty calculator suggests 1.2 11.5 gram packs of US-05 for 5 gallons of 1.075 wort. One pack should be close enough.

If you were using very fresh liquid yeast (001/1056) you'd need a 2 liter starter with intermittent shaking, or else 2 vials and a 1 liter starter.

Just check his calculator before every batch.

Or...., pitch the yeast into half the wort, let it work overnight, then combine the unfermenting half with the fermenting half.

Quote:
On brew day sanitize two fermentors. Chill the wort and pour half into each one. Pitch the yeast into your primary fermentation vessel, and seal both containers. The following day, just like a starter, your yeast will have grown significantly. Pour the wort from the second container into the primary fermentation vessel. As a bonus, pour as vigorously as you like. Aeration is beneficial at this stage of fermentation.

This is interesting, I've not heard of this before but it makes sense

1 packet is fine for 1.075. Make sure you hydrate it rather than toss it onto the wort to ensure high cell viability.

Anything else is un-necessary extra work.
