| JY029 - Belgian Wit I || Hoegaarden || 70-77 || Low || 63-76 || Spicy and phenolic, with a nice estery finish. Great for witbier, Grand Cru-style wit and specialty beers. Belgian Styles, mainly Belgian Wit and Grand-Cru, but does well in Blonde, Belgian Tripel and Specialty

| JY031 - Nova Ale Yeast || Ashburn, Virginia || 71-80 || Very low || 68-85 || A true local strain! Isolated in Ashburn, Virginia in 2008. The first native Virginia yeast used in commercial beer since prohibition (Farmwell Wheat and Native Son, both Lost Rhino Brewing Company). Higher fermentation temperatures are preferred with this strain. Producer of high levels of fruitiness above 26 ºC (80 ºF), earthy notes are present at lower fermentation temperatures (20 ºC, 68 ºF). Since it is a wild Saccharomyces cerevisiae strain one can expect drift when repitched for many generations.

| JY056 - Poperinge Saison || Famous Brasserie in Southern Belgian/Northern France region. || 79-85 || Very low || 65-77 || Aggressive, attenuative and outspokenly estery and peppery. Great for Saison and Farmhouse style beers at higher temperatures, in the lower range good for more traditional Belgian styles. Good to finish off a beer that has problems fermenting with another yeast.
| JY104 - Benedict Abbey || Small brewery in Flemish Brabant, Belgium. || 75-80 || Low || 68-77 || JY104 was handed to Jasper Akerboom when he toured some small microbreweries in the Netherlands and Belgium by a friendly microbrewer. This strain originally belonged to a small brewery in Flemish Brabant in Belgium. The brewery was acquired by a large macrobrewery, and management decided to do away with this precious yeast. Fortunately passionate homebrewers and beer enthusiasts were able to keep some of the yeast going and you can use it now as well! This strain ferments fast, and aggressive. It can be under pitched easily, and attenuates deep. Great esters and phenols, can be slightly peppery. Flocculates slow, but can withstand spunding without a problem. This yeast is great for lighter colored Belgians, but is great for darker Belgians as well. This strain has not been fully characterized, so we do not know what gravity this yeast will ferment. We do know that it attenuates very well, and the initial tests have indicated that can ferment easily to 10% ABV.

| JY31 JY110 - Nova Ale Yeast || Ashburn, Virginia || 71-80 || Very low || 68-85 || A true local strain! Isolated in Ashburn, Virginia in 2008. The first native Virginia yeast used in commercial beer since prohibition (Farmwell Wheat and Native Son, both Lost Rhino Brewing Company). Higher fermentation temperatures are preferred with this strain. Producer of high levels of fruitiness above 26 ºC (80 ºF), earthy notes are present at lower fermentation temperatures (20 ºC, 68 ºF). Since it is a wild Saccharomyces cerevisiae strain one can expect drift when repitched for many generations. |-| JY31 - Nova NOVA Ale Yeast 2 || Northern Virginia || 75-80 || Low || 75+ -100 || A new NOVA Ale yeast! This yeast differs from JY031 Nova Ale Yeast 1 by being slight more toned down in the aromatics and flavor department. Isolated in Northern Virginia, this strain is truly local. Power to VA! Since this is a new variety of Saccharomyces cerevisiae, this strain has not been fully characterized yet. Feel free to share your information with us if you use this strain! This strain will be perceived slightly Belgianesque, but at lower fermentation temperatures will be lower in aromatics. Can slow down when temperature is low. Likes it warm.

| JY146 - Protocetid Ale || Calvert Marine Museum in Solomons, MD. || >80 || Very low || max 90 || This yeast is the famous strain isolated from the Calvert Marine Museum in Solomons, MD. This strain was isolated from Protocetid bone, discovered by Jason Osborne, the president and co-founder of Paleo Quest, a non-profit citizen-science organization for the advancement of the sciences of paleontology and geology through material contributions to museum collections, field exploration, scientific publication and education. This yeast is used for the famous Lost Rhino Brewing Company Bonedusters Ale. This yeast is hard to work with, it has the tendency to stop fermenting for a week after 30% attenuation, after which it picks back up and finishes out. Not for the faint of heart! Expect a Belgian character, with some tartness. Keep the desired ABV low during your recipe development, this strain is not suited for high-gravity worts. Finishes crisp and fruity, with a pleasant fizz.
