Bell's Brewing out of Michigan has issued a special release beer for each 1000 batches, (i.e. Batch 1000, Batch 2000, etc). Well they recently released the final beer in this series, Batch 10,000 and their inspiration for this brew was "cleaning out the Brewers Closet". It has over 190 ingredients.

From the Bell's Website:

While we are excited to free up some brewing space for other creative projects, the end of the Batch series marks a major milestone for us, and is a little bittersweet being the end of an era. Batch 10,000 reflects our homebrewing roots and was inspired by the the last homebrew of the season. Our owner Larry Bell remembers going through his brewing supplies and making the last homebrew out of whatever malts and hops were left from his brewing months. With this being the motivation behind our last commemorative batch series beer, we combed through the catalogs of many malt and hop suppliers to source 100 different malts, grains, and other fermentables. This is balanced by the addition of 60 different hop varietals between the kettle and dry hopping. The resulting beer presents a deep, chocolate brown hue and offers roasted and caramel notes from the malts mixed with an assertive hop character. Feel free to drink it fresh, or vintage age it as you please.
