Re: [DIYbio] Minimum ethanol % to precipitate strawberry DNA?

Poteen comes in different grades, like absynthe (could be 60,80,95 etc), but is illegal regardless so it's hard to come by.

yeah, that will definitely turn rum into gel.  Btw, the rums you are looking probably aren't 75 and 63 PERCENT, but proof.  75 percent would be bacardi 151, i doubt you'll find another rum at that concentration, and regular rum is generally 75 to 80 PROOF, which is 30-40 percent.  Looking around, I'm finding Poteen is a common irish whiskey you can get, its 90 percent (180 proof), that should be enough to do the trick.

No everclear in the UK, but thanks for the rum gel tip. It will be at -20.

From what I recall, temp is just as important, and at the lower temps of ethanol we usually used, rum is going to turn into gel.  I'd extract using Everclear or similar, and then mix.

We're going to make some DNA daiquiris for the London Hackspace spacewarming party this Sunday 12th May. The original recipe calls for a 75% rum, but not wanting to spend £80 on alcohol, we're looking at a cheaper 63% rum.

What's the minimum % you can use, and will yield be lower at lower ethanol concentrations?
