We distill in our Holstein pot stills using one pass distillation, but make a small "heads" cut and a fairly large "tails" cut and put about 4 liters of tails into the next still run. The proof at time of distillation is about 150 (75%). Then we reduce in proof and barrel-age the rough distillate in old sherry casks. All the Oregon Single Malt now spends some time in barrels made from air-dried Oregon Oak. The present bottling is only 3 years old but we think it is remarkably smooth for such a young whiskey. The result is a smooth, peat-y whiskey with a surprisingly clean finish. Production is very limited because what we put in the barrel doesn't come out for years.
