A new collaboration is brewing between Upland Brewing and New Belgium Brewing, driven by a series of blending experiments with sour ales from each side. Two unique blended wild ales were created using a variety of beers, resulting in Light Synth and Dark Synth.

So what’s in the blend? Ask, and you shall receive.

Light Synth:

• 50% New Belgium Felix
• 40% Upland Sour Reserve
• 10% Upland Cherry Lambic

Dark Synth:

• 50% New Belgium Oscar
• 40% Upland Dantalion
• 10% Upland Raspberry Lambic

New Belgium will be debuting a special version of Light Synth with 10% Boon Kriek as well as Dark Synth during the Festival of Barrel-Aged Beer (FOBAB) on Saturday, November 16. Upland will package both blends in 750mL bottles for release in early 2014.
