Notes:

Drinkability and Notes: Goes down really easily. No off flavors, but leaves something to be desired. Changes for next time: shows promise as a golden base. Main problems to combat: it's slightly watery, lacks body and fermentation character, and shows a little too much cereal. Consider bumping the ABV up to 6, cutting the oats in half to knock down that cereal note, try Vermont Ale and London III and other yeasts that might add a little more playful fermentation character; unmalted/raw wheat or something else to lend a little more body and richness.

Notes:

Appearance: Golden with orange hues. Medium haze. Pours a fluffy head that dissipates quickly. Aroma: white grape, peach, yuzu, vanilla, caramel, fruit-loops, subtle honey-oat cherrio-like note. Taste: Much of what you'd expect from the nose, but the cereal note joins the fruit more loudly on the palette. Up front you get a lean citrus note that renders more like orange/pineapple-juice. A little creaminess follows in the middle. Oats and cereal notes bloom on the finish with a soft, lactic acidity. Mouthfeel: light, bright, high-toned and clean, but a bit watery. Lacks body. A touch of sliminess (from the bottle yeast).
