Fores percentage with single malt


Recommended Posts

Curious your collective thoughts.  Single malt spirit run.  Collected 100% of low wines of a very clean fermentation to 12%.  What percentage of the spirit run will be fores?

Depends quite a bit on how long you are going to age it. If you want a quick turnaround I suggest taking a big fores cut, if your conditions allow and you can age for say 10 years then you can get away with a much smaller cut, the angels will assist with removing some of the fores. 

As long as you re-cycle the fores and don't throw out every time, a big cut is not a waste of your hard won spirit.

This!   the cut points will differ based on how long you age it.   I'd also note that they differ with different equipment.   You will have a bigger cut on a pot still for example than on a column still.

Are we all using the terms the same way though?   The way I use these terms, fores are the part that is not recycled.  (as opposed to the "heads" that didn't make the blending cut)

Rather than a fixed percentage, some will use the vapor temperature to help determine cuts, as you can infer some information about the contents of the vapors from the temps for fores.       Thinking volumetrically, you may lose some of the potentially recyclable ethanol that way, but it's also easy and can give nice margins at the cost of efficiency.   I believe the thinking on that was 1 tablespoon per gallon of original mash with a Pot Still.   Less for a column still as they are better at concentrating heads.

Most of the Australian and Scottish distillers I know end up with 3 products at the end of the spirit run. 

Most common terms I hear are Fores, heart, feints.  

It appears as if many US distillers end up with 4 products.

Is this the order  Fores - Heads - Hearts - Feints?   

Also often hear  ........ - Middle cut - Tails,

but in general is it Fores or Heads that come off first?

I use the terms similarly to Jon, first couple of ounces of Fores come off first, which I don't recycle into the next batch, just so I'm not building up methanol. Heads come next, they don't make it into the final blend, but do get recycled into the next batch. Hearts are everything that gets bottled. Tails come last, and feints are the mix of heads and tails that all go into the next distillation.
