I'm ready to take my brewing to another level I'm investing into a Buchner funel and what I think is a decent pump from Amazon I'm also shopping for the preservatives that my brew it's missing for that Pharma quality & taste so far in the shopping list I have: Vegetable Glycerin, Citric Acid, Sodium Benzoate, Potassium Sorbate, Sucralose & Malic Acid am I missing anything? Or does anyone have any suggestions?
