There's a pretty weird combination of liters and ounces in soft drinks. 2 L and 20 oz are very (most?) common for bottled soda. 1 gal is common for bottled water, but for individual bottles, 0.5 L (16.9 oz) is common. 1 L and 1.5 L bottles of various beverages are not unheard of. Cans of soda are generally 12 oz, though 16 oz and 24 oz are not uncommon among beers. Wine, as mentioned below, is often 750 mL, but liquor is often sold by the quart. So I wouldn't say the 2 L bottle is the sole anomaly, but metric is definitely not the prevalent system for beverages.
