It seems I've been cursed by the brewing gods, my past 5 batches have all had some sort of problem.
Let's begin with I've been brewing for the past 3 years and have never faced this problem, all my brews had come up great except for this past month.
I have a friend that has a restaurant ( BTW I don't live in the US so I don't really want to get into regulations and permits discussions) and he tried my English pale ale (standard bitter) and he liked it he has tried it in several occasions and he really loves it. He proposed that I deliver 48 bottles every week to his restaurant and that he can help me, 1 - to sell them and 2 - get funding to set up a small brewery. Since then all my batches seem to hit a problem or another.
Batch 1 was ok out of primary (7 days) and on secondary ( 14 days) gravity was spot on as well as flavor (og 1.036 fg 1.008 ) fermented with u-04. Temp was around 19-20 C. Bottles went through standard sanitization process (detergent washing with hot water wait to dry, then starsan). Made a table sugar water solution to carb in bottle. 2 days after bottling on the neck bottle a small film appeared. Not too strong but still a small flim that clinged to the side of the bottle with movement and to the top of the beer. ( my first guess acetobacter) 2 weeks after fermenting the bottles are well carbonated and they have a slight acidic aftertaste can be felt in the back of the mouth. I'm hoping this is just that the beer is green.
Batch 2 was ok out of primary (7 days) and on secondary up to day 12 on day 13 it developed a white pelicule gravity was spot on as well as flavor when I moved to bottling (og 1.036 fg 1.008 ) fermented with u-04. Temp was between 20-21 C. Bottles went through standard sanitization process. Made a table sugar water solution to carb in bottle. 1 day after bottling on the neck bottle a small film appeared. Not too strong but still a small flim that clinged to the side of the bottle with movement and to the top of the beer. 2 weeks after fermenting the bottles are well carbonated and they have a slight but more pronounced acidic aftertaste can be felt in the back of the mouth. I'm guessing this is infected
Batch 3 tasted off after primary really acidic and developed a white pelicle after 1 day in secondary. That went straight to the trash.
Batch 4 was the same as batch 2 but it developed a pellicle after 7 days of secondary. Beer tastes like acid after bottling. The pellicle on the bottle was white. All got discarded. The fermenting temperature was about 22-23C the upper limit for u-04 but 3 C outside the recommended fermenting temp.
Batch 5 went exactly the same as batch 1
I always ferment on plastic buckets and do secondary on plastic carboys. However to keep the temp I had to place the buckets's inside water containers, the water level went to about half the height of the bucket. So this is also something new I've done and I don't know if the problem is in the cooling method or if I'm just in a really bad streak and somehow my beer oswaldo getting infected.
Like I said no problems in 3 years I want to do something to sell and all hell breaks loose.
Any tips or comments would be greatly appreciated.
Cheers
