WHAT'S IN THE BOTTLE? Mashbuild Signature Batch, Oloroso Sherry Barrel
Oloroso sherry has long been the primary finish to some of the finest single malt whiskies. We thought it was important to try the same with the U.S single malt.
All Mashbuild bourbon is solera-aged, meaning that barrels of similar ages are grouped together in a common “layer” of the solera.
Specifically, this batch was finished in a used barrel from Jerez Xeres, Spain.
In the solera aging process, as whiskey is used, barrels are backfilled with stock from the next layer up and new stock is added to the top layer. In this fashion, younger spirits take on more mature flavors and the average age of stock in the solera always increases over time.
