Notes

Jolly Pumpkin Bam Biere clone as published in 'Session Beers: Brewing for Flavor and Balance' by Jennifer Talley.

**Mixed cultures are either/or, not both. Free rise temperature to 80° F (27° C) and above, do not control temperature during fermentation. Step down to 50-55° F (10-13° C) once fermentation is complete.

Using the bottle dregs from a Bam Biére to inspire a secondary fermentation in a small oak barrel is probably the best way to recreate this beer at home. The other option is to purchase a mixed culture packet and some oak cubes or spirals and add to the secondary carboy after primary fermentation. **It may take up to 18 months for mixed culture to fully develop flavor and acidity.
