Do you ship chocolate during warm weather or to warmer parts of the country?

Mast reserves the right to charge a $15 shipping fee when shipping to warmer parts of the country. We select the appropriate packing materials such as heat-tempered, insulated boxes and frozen gel packs to ensure that your order arrives in perfect condition.

What are other restricting temperature concerns?

Mast advises against chocolate deliveries to warmer countries during summer months (generally April through mid-September) or to destinations higher than 20 degrees centigrade. Chocolate confections are subject to temper or alter from their original form under unstable conditions. We cannot accept responsibility or offer any guarantees as we cannot control temperature conditions.

Product Information

What do the percentages mean on each bar of chocolate?

The percentage is an indicator of the intensity or mildness of the chocolate. It’s a matter of preference and taste, not percentages. Choose your own favored varieties!

How long will my chocolates stay fresh? How should I store chocolate? 

All Mast chocolates are labeled with a "Best By" date. Products kept beyond this recommended date may undergo texture, flavor or other changes. We recommend you store your bars in a cool, dry environment and avoid heat or moisture at all costs. As a general rule, we do not recommend storing your Mast Chocolate in the refrigerator, but in a cool, dark pantry. 

Maintain freshness after opening by storing at temperatures that do not exceed 65F (18C). Avoid heat, humidity, and direct sunlight. To store chocolate for a longer duration, wrap the package in plastic, close tightly, and refrigerate.

Do your chocolates contain soy? Are they gluten-free?

Our chocolates are made in facilities that handle soy and gluten and other allergens. We do not add preservatives or emulsifiers to our products, and we avoid cross contamination in all ways possible. 

The only bar that contains soy + gluten is the Miso & Sesame bar from the Los Angeles Collection. 

Do your chocolates contain dairy?

Our Milk Chocolate collection contains dairy. Our chocolate is produced in facilities that handle allergens like dairy.

Do your chocolates contain nuts?

Our Almond bar contains nuts. Our chocolate is produced in facilities that handle allergens like nuts.
