Usually metals are acid sensitive, so with that respect the zinc should be fine. However, zinc is a catalyst for certain organic reactions. Since your are performing an organic reactions (transesterfication) you may induce other reactions that you don't want. Also you may not be able to get the galvanization as clean as you want. For lab settings glass is used for its nonreactiveness. For an industrial scale stainless would probably be better or a dedicated plastic container designed for the purpose. The second problem with galanization is it is just a surface treatment. The zinc 'rusts' and in doing so sets up an electric current that prevents the underlying iron from corroding (cathodic protection). The iron is protected only until there is no zinc left. Heating and cooling could accelerate this process and destroy the barrel. Stainless steel uses cathodic protection as well but the chromium is fully interspersed, not just a surface plating.
Finally, you should be careful about where you get your information, may of the sites do not correctly describe the process (you never actually form methoxide by mixing lye and methonal) and the technique for titration are usually not very accurate. These might not seem like big deals but lye can be just as dangerous as battery acid and not fully understanding what you are doing could lead to a dangerous situation.

PS warming the oil won't dry it unless you get above the boiling point of water, and think of what happens when you bacon in a hot pan of grease........(a funnel separator would be better to get most of the water out)
