There is no need to lug around heavy glass carboys any longer! The Vintage Shop's Plastic Carboys are made from 100% Virgin PET plastic, making them lighter than glass. They are impermeable to oxygen, which improves the quality & fermentation of your beer & wine! Able to withstand 15 psi of pressure, they are safer than glass & highly durable. The punt base allows for ease of carrying & pouring with minimal sediment movement, while the extra head space facilitates thermal expansion during fermentation. With no ribs on the sides to collect yeast, cleaning & sanitizing is much easier. Carboy sizes align with volumes of most wine kits, making these the ideal choice for secondary fermentation of your wine.
