Back in 2001, 2002, and 2003, I brewed at least a couple batches of lambic each year. In 2004, I blended some one-year-old, two-year-old, and three-year old lambic to make a gueuze (a blended lambic). The beer turned out well. It won Best of Show at the 2004 Austin ZEALOTS Inquisition. And, I had 15 gallons (57 L) of it as each blender was 5 gallons (19 L) in volume. There are better gueuze blending strategies than this, but at the time I did not know them. Even so, this was one of the coolest things I ever did as a homebrewer, and I even wrote about it awhile ago.
With 15 gallons (57 L) of beer into to put into bottles, I had to scrounge around to find every available package I had. Along with a few cases of 22-ounce (650-mL) bottles, I ended up using several 1 L bombers to hold some of the beer. After bottling, I set the 1 L bombers aside . . . and forgot about them.
A couple weeks ago, while scrounging around my brewing equipment, I found them. So, suddenly I had six bombers of gueuze that was 10 years old. I immediately put one of the bottles in my fridge, let it cool overnight, and sampled it the next evening. I sampled a couple other bottles in the past few weeks, too. Here is what I found.
