Grand Rapids Brewing Company is now offering our first-ever bottle conditioned beer, Sur La Lune golden ale -- French for “on the moon” -- was packaged using the unique process of bottle conditioning. This involves an extra blast of yeast and sugar and a second period of fermentation after the bottles are corked and caged. It allows carbonation to occur naturally and causes the beer to age in a manner similar to wine. The pressure of the cork on the additional yeast and sugar enhances flavors, carbonation, aromatics and alcohol content, providing an all-around better summer drinking experience.
“Bottle conditioned beers have more depth and character than their draft counterparts and a finer carbonation and mouth feel, plus corks and cages are just fun and fancy,” said Ernie Richards, GRBC’s Brewhouse Alchemist. (Sur La Lune also will be available in its tap form for samples and drafts.)
Its companion beer, Sur Les Nuages -- “on the clouds” -- first appeared in the 2017 Beer City Pro-Am Cup competition as a collaboration between GRBC and award-winning homebrewer Nick Rodammer. It comes from the same base recipe as Sur La Lune, but is force-carbonated, capped and fermented solely with a special Brettanomyces (a.k.a. "Bret") yeast isolate. The result is a floral, lightly tropical golden ale with grapefruit notes and no sourness.
The team at GRBC will continue expanding the bottle conditioned sour ale project through the summer, and we're tentatively planning to release Ciel De Nuit -- “night sky” -- sour stout and Petit Chouette -- “little owl” -- a dry-hopped oude saison, in the upcoming months.
