History
From Local Production to Visitor Site
Green Frog Distillery has built a profile as a local, visitor-friendly distillery in Keokuk. Guest testimonials highlight tours, tastings, and close contact between staff and visitors, and the company offers direct sales from its premises. The range spans from a clear 100-proof straight corn whiskey to flavored bottles and small, barrel-aged batches, showing a development from a basic product to multiple parallel product lines.
Raw Materials and Production
The production uses corn and rye.
Storage occurs under the following conditions: Charred oak barrels in several sizes (10, 15 and 53 gallons) are used for aging.
Special production features include: Producing a clear 100-proof straight corn whiskey as the base product, Blending corn with rye to Corn & Rye Blend, Flavoring the base into variants such as coffee, pear, caramel, and cranberry, Barrel aging in charred oak barrels in several sizes with hand-numbered batches, Locally produced corn whiskey, Small batches and hand-written batch numbers on barrel-aged bottles, and Direct-to-consumer sales from the distillery's shop.
Aging and Barrel Types
Aging takes place in charred oak barrels of various sizes: 10-, 15-, and 53-gallon casks are used. Documented batches show aging times from around 2 years and 8 months up to 4 years, and some batches are described with finish labels such as "rich & smooth finish" or "dark charred oak finish." Different barrel sizes and ages are used deliberately to create variation among the hand-numbered, small batches.
Whiskies
The range includes a clear Straight Corn Whiskey (100 proof) as the foundation, a Corn & Rye Blend (90 proof), a Barrel Aged Corn Whiskey (96 proof) released in hand-numbered small batches, and several flavored variants: Coffee (66 proof), Pear (70 proof), Caramel (60 proof) and a seasonal Cranberry (60 proof). The products range from mixer-friendly bases to flavored bottles and experimental barrel aging, providing both everyday use and the opportunity to try small, aged expressions.
