Occasional feeding has been shown to keep ''Brettanomyces'' alive in beer for brewers who do not have a lab, however many variables may come into play as far as how effective this will be for individual strains and in different environments. Although no research has been done to indicate what the best practices are for feeding ''Brettanomyces'' to keep it alive in beer, we recommend trying this method: every 3-6 months swirl the vessel so as to suspend all of the yeast and then decant 70-90% of the beer and suspended yeast slurry, and replace it with a 1.040 starter wort with yeast nutrients. This method will discard a lot of the old yeast cells, while retaining enough living cells for replication <ref>[https://www.facebook.com/groups/MilkTheFunk/permalink/1345924532102424/?comment_id=1345979272096950&reply_comment_id=1346020438759500&comment_tracking=%7B%22tn%22%3A%22R3%22%7D Conversation with Mark Trent and Richard Preiss on MTF regarding occasional feeding of ''Brettanomyces'' to keep it alive. 07/07/2016.]</ref>. Some strains may survive extended periods of aging in beer, however their viability and vitality will be greatly reduced over time. Interestingly, ''Brettanomyces'' remains '''more''' viable over time if it was co-fermented with ''S. cerevisiae'' than if it was fermented without the presence of ''S. cerevisiae''; i.e. [[100%25_Brettanomyces_Fermentation|100% ''Brettanomyces'' beers]] or ''Brettanomyces'' and ''Lactobacillus <ref name="Hubbe"></ref>.
Another method for storing ''Brettanomyces'' has reportedly worked for MTF member Justin Amaral. This method involves storing the culture in isotonic sodium chloride. ''Brettanomyces'' cultures have been reported by Amaral to survive at least for 6-7 months. This includes other microbes as well (RVA Orchard Brett, ECY Dirty Dozen, Bright Yeast Labs Brett Chateaux, ''T. delbrueckii'', ''L. plantarum'' isolated from goodbelly, Omega Lacto blend, ''Pediococcus damnosus'', Bootleg Biology Sour Weapon, and Funk Weapon 2 and 3, and a ''Brettanomyces'' isolate from Yeast Bay).
